2015-06-25checkpatch: add --strict warning for c99 fixed size typedefs : int<size>_tJoe Perches1-6/+25
Using declarations like u_int16_t in kernel code is not preferred. Suggest the kernel sized types instead of the c99 types when not in the uapi directory. Add a $typeC99Typedefs variable for the types to check and neaten the other typedef variables.

2015-06-25checkpatch: check for uncommented waitqueue_active()Joe Perches1-0/+7
Linus sayeth: : Pretty much every single time people use this "if : (waitqueue_active())" model, it tends to be a bug, because it means : that there is zero serialization with people who are just about to go : to sleep. It's fundamentally racy against all the "wait_event()" loops : that carefully do memory barriers between testing conditions and going : to sleep, because the memory barriers now don't exist on the waking : side. : : So I'm making a new rule: if you use waitqueue_active(), I want an : explanation for why it's not racy with the waiter.

Section headers can be quite long and some are very long and duplicated for many initial characters. The current maximum length emitted for a section header is 20 bytes (or 17 bytes then ... when the section header length is > 20). Change that length to 50 so more of the section is shown.

2015-06-22Merge branch 'x86-core-for-linus' of ↵Linus Torvalds1-1/+1
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 core updates from Ingo Molnar: "There were so many changes in the x86/asm, x86/apic and x86/mm topics in this cycle that the topical separation of -tip broke down somewhat - so the result is a more traditional architecture pull request, collected into the 'x86/core' topic. The topics were still maintained separately as far as possible, so bisectability and conceptual separation should still be pretty good - but there were a handful of merge points to avoid excessive dependencies (and conflicts) that would have been poorly tested in the end. The next cycle will hopefully be much more quiet (or at least will have fewer dependencies). The main changes in this cycle were: * x86/apic changes, with related IRQ core changes: (Jiang Liu, Thomas Gleixner) - This is the second and most intrusive part of changes to the x86 interrupt handling - full conversion to hierarchical interrupt domains: [IOAPIC domain] ----- | [MSI domain] --------[Remapping domain] ----- [ Vector domain ] | (optional) | [HPET MSI domain] ----- | | [DMAR domain] ----------------------------- | [Legacy domain] ----------------------------- This now reflects the actual hardware and allowed us to distangle the domain specific code from the underlying parent domain, which can be optional in the case of interrupt remapping. It's a clear separation of functionality and removes quite some duct tape constructs which plugged the remap code between ioapic/msi/hpet and the vector management. - Intel IOMMU IRQ remapping enhancements, to allow direct interrupt injection into guests (Feng Wu) * x86/asm changes: - Tons of cleanups and small speedups, micro-optimizations. This is in preparation to move a good chunk of the low level entry code from assembly to C code (Denys Vlasenko, Andy Lutomirski, Brian Gerst) - Moved all system entry related code to a new home under arch/x86/entry/ (Ingo Molnar) - Removal of the fragile and ugly CFI dwarf debuginfo annotations. Conversion to C will reintroduce many of them - but meanwhile they are only getting in the way, and the upstream kernel does not rely on them (Ingo Molnar) - NOP handling refinements. (Borislav Petkov) * x86/mm changes: - Big PAT and MTRR rework: making the code more robust and preparing to phase out exposing direct MTRR interfaces to drivers - in favor of using PAT driven interfaces (Toshi Kani, Luis R Rodriguez, Borislav Petkov) - New ioremap_wt()/set_memory_wt() interfaces to support Write-Through cached memory mappings. This is especially important for good performance on NVDIMM hardware (Toshi Kani) * x86/ras changes: - Add support for deferred errors on AMD (Aravind Gopalakrishnan) This is an important RAS feature which adds hardware support for poisoned data. That means roughly that the hardware marks data which it has detected as corrupted but wasn't able to correct, as poisoned data and raises an APIC interrupt to signal that in the form of a deferred error. It is the OS's responsibility then to take proper recovery action and thus prolonge system lifetime as far as possible. - Add support for Intel "Local MCE"s: upcoming CPUs will support CPU-local MCE interrupts, as opposed to the traditional system- wide broadcasted MCE interrupts (Ashok Raj) - Misc cleanups (Borislav Petkov) * x86/platform changes: - Intel Atom SoC updates ... and lots of other cleanups, fixlets and other changes - see the shortlog and the Git log for details" * 'x86-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (222 commits) x86/hpet: Use proper hpet device number for MSI allocation x86/hpet: Check for irq==0 when allocating hpet MSI interrupts x86/mm/pat, drivers/infiniband/ipath: Use arch_phys_wc_add() and require PAT disabled x86/mm/pat, drivers/media/ivtv: Use arch_phys_wc_add() and require PAT disabled x86/platform/intel/baytrail: Add comments about why we disabled HPET on Baytrail genirq: Prevent crash in irq_move_irq() genirq: Enhance irq_data_to_desc() to support hierarchy irqdomain iommu, x86: Properly handle posted interrupts for IOMMU hotplug iommu, x86: Provide irq_remapping_cap() interface iommu, x86: Setup Posted-Interrupts capability for Intel iommu iommu, x86: Add cap_pi_support() to detect VT-d PI capability iommu, x86: Avoid migrating VT-d posted interrupts iommu, x86: Save the mode (posted or remapped) of an IRTE iommu, x86: Implement irq_set_vcpu_affinity for intel_ir_chip iommu: dmar: Provide helper to copy shared irte fields iommu: dmar: Extend struct irte for VT-d Posted-Interrupts iommu: Add new member capability to struct irq_remap_ops x86/asm/entry/64: Disentangle error_entry/exit gsbase/ebx/usermode code x86/asm/entry/32: Shorten __audit_syscall_entry() args preparation x86/asm/entry/32: Explain reloading of registers after __audit_syscall_entry() ...

2015-06-16kconfig: add xenconfig defconfig helperLuis R. Rodriguez1-0/+5
This lets you build a kernel which can support xen dom0 or xen guests on i386, x86-64 and arm64 by just using: make xenconfig You can start from an allnoconfig and then switch to xenconfig. This also splits out the options which are available currently to be built with x86 and 'make ARCH=arm64' under a shared config. Technically xen supports a dom0 kernel and also a guest kernel configuration but upon review with the xen team since we don't have many dom0 options its best to just combine these two into one. A few generic notes: we enable both of these: CONFIG_INET=y CONFIG_BINFMT_ELF=y although technically not required given you likely will end up with a pretty useless system otherwise. A few architectural differences worth noting: $ make allnoconfig; make xenconfig > /dev/null ; \ grep XEN .config > 64-bit-config $ make ARCH=i386 allnoconfig; make ARCH=i386 xenconfig > /dev/null; \ grep XEN .config > 32-bit-config $ make ARCH=arm64 allnoconfig; make ARCH=arm64 xenconfig > /dev/null; \ grep XEN .config > arm64-config Since the options are already split up with a generic config and architecture specific configs you anything on the x86 configs are known to only work right now on x86. For instance arm64 doesn't support MEMORY_HOTPLUG yet as such although we try to enabe it generically arm64 doesn't have it yet, so we leave the xen specific kconfig option XEN_BALLOON_MEMORY_HOTPLUG on x86's config file to set expecations correctly. Then on x86 we have differences between i386 and x86-64. The difference between 64-bit-config and 32-bit-config is you don't get XEN_MCE_LOG as this is only supported on 64-bit. You also do not get on i386 XEN_BALLOON_MEMORY_HOTPLUG, there does not seem to be any technical reasons to not allow this but I gave up after a few attempts.

2015-06-15scripts/package/Makefile: rpmbuild is needed for rpm targetsJim Davis1-6/+2
Before rpm release 4.1, in 2002, either the rpm command or the rpmbuild command could be used in the rpm-pkg or binrpm-pkg targets, and the Makefile chose the rpm command if the rpmbuild command wasn't found. After release 4.1, however, the rpm command could no longer be used in place of the rpmbuild command. As the rpmbuild command is not installed by default, this can lead to failures with the rpm-pkg and binrpm-pkg targets: rpm --define "_builddir ." --target \ x86_64 -bb ./binkernel.spec rpm --target: unknown option scripts/package/Makefile:60: recipe for target 'binrpm-pkg' failed Change the Makefile to use rpmbuild unconditionally to avoid this.

2015-06-15kconfig: allow use of relations other than (in)equalityJan Beulich5-11/+177
Over the years I found it desirable to be able to use all sorts of relations, not just (in)equality. And apparently I'm not the only one, as there's at least one example in the tree where the programmer assumed this would work (see DEBUG_UART_8250_WORD in arch/arm/Kconfig.debug). Another possible use would e.g. be to fold the two SMP/NR_CPUS prompts into one: SMP could be promptless, simply depending on NR_CPUS > 1. A (desirable) side effect of this change - resulting from numeric values now necessarily being compared as numbers rather than as strings - is that comparing hex values now works as expected: Other than int ones (which aren't allowed to have leading zeroes), zeroes following the 0x prefix made them compare unequal even if their values were equal.

2015-05-25Kconfig: Remove bad inference rules expr_eliminate_dups2()Martin Walch1-111/+0
expr_eliminate_dups2() in scripts/kconfig/expr.c applies two invalid inference rules: (FOO || BAR) && (!FOO && !BAR) -> n (FOO && BAR) || (!FOO || !BAR) -> y They would be correct in propositional logic, but this is a three-valued logic, and here it is wrong in that it changes semantics. It becomes immediately visible when assigning the value 1 to both, FOO and BAR: (FOO || BAR) && (!FOO && !BAR) -> min(max(1, 1), min(2-1, 2-1)) = min(1, 1) = 1 while n evaluates to 0 and (FOO && BAR) || (!FOO || !BAR) -> max(min(1, 1), max(2-1, 2-1)) = max(1, 1) = 1 with y evaluating to 2. Fix it by removing expr_eliminate_dups2() and the functions that have no use anywhere else: expr_extract_eq_and(), expr_extract_eq_or(), and expr_extract_eq() from scripts/kconfig/expr.c Currently the bug is not triggered in mainline, so this patch does not modify the configuration space there. To observe the bug consider this example: config MODULES def_bool y option modules config FOO def_tristate m config BAR def_tristate m config TEST1 def_tristate y depends on (FOO || BAR) && (!FOO && !BAR) if TEST1 = n comment "TEST1 broken" endif config TEST2 def_tristate y depends on (FOO && BAR) || (!FOO || !BAR) if TEST2 = y comment "TEST2 broken" endif config TEST3 def_tristate y depends on m && !m if TEST3 = n comment "TEST3 broken" endif TEST1, TEST2 and TEST3 should all evaluate to m, but without the patch, none of them does. It is probably not obvious that TEST3 is the same bug, but it becomes clear when considering what happens internally to the expression m && !m": First it expands to (m && MODULES) && !(m && MODULES), then it is transformed into (m && MODULES) && (!m || !MODULES), and finally due to the bug it is replaced with n. As a side effect, this patch reduces code size in expr.c by roughly 10% and slightly improves startup time for all configuration frontends.

UTMI+ Low Pin Interface (ULPI) is a commonly used PHY interface for USB 2.0. The ULPI specification describes a standard set of registers which the vendors can extend for their specific needs. ULPI PHYs provide often functions such as charger detection and ADP sensing and probing. There are two major issues that the bus type is meant to tackle: Firstly, ULPI registers are accessed from the controller. The bus provides convenient method for the controller drivers to share that access with the actual PHY drivers. Secondly, there are already platforms that assume ULPI PHYs are runtime detected, such as many Intel Baytrail based platforms. They do not provide any kind of hardware description for the ULPI PHYs like separate ACPI device object that could be used to enumerate a device from.

2015-05-06builddeb: fix stripped module signatures if CONFIG_DEBUG_INFO and ↵Andrey Skvortsov1-0/+6
CONFIG_MODULE_SIG_ALL are set If CONFIG_MODULE_SIG_ALL is set, then user expects that all modules are automatically signed in the result package, as it's for rpm-pkg, binrpm-pkg, tar, tar-*. For deb-pkg this is correct only if CONFIG_DEBUG_INFO is NOT set. In that case deb-package contains signed modules. But if CONFIG_DEBUG_INFO is set, builddeb creates separate package with debug information. To do that, debug information from all modules is copied into separate files by objcopy. And loadable kernel modules are stripped afterwards. Stripping removes previously (during modules_install) added signatures from loadable kernel modules. Therefore final deb-package contains unsigned modules despite of set option CONFIG_MODULE_SIG_ALL. This patch resigns all stripped modules if CONFIG_MODULE_SIG_ALL is set to solve this problem.

2015-04-29scripts/dtc: add missing libfdt and fixups to import scriptGaurav Minocha1-0/+9
The following script is used to import dtc upstream into kernel. It was missing import of dtc/libfdt, with this commit it will include the same. Also, currently in arch and driver code that needs early access to the flattened device tree it is necessary to add specific CFLAGS so that when scripts/dtc/libfdt/libfdt.h is included the C preprocessor is able to locate the libfdt versions of libfdt_env.h and fdt.h without generating an error. So, this script replaces angular brackets with quotation used to include header files fdt.h and libfdt_env.h Signed-off-by: Gaurav Minocha <[email protected]> [robh: reword commit headline and add 'git add'] Signed-off-by: Rob Herring <[email protected]>
2015-04-27deb-pkg: move setting debarch for a separate functionRiku Voipio1-7/+11
create_package() function tries to resolve used architecture for everry package. Split the setting the architecture to a new function, set_debarch(), called once on startup. This allows using debarch from other parts of script as needed. v2: Follow Michals suggestion on setting variables at top scope and also setting the fallback $debarch in the new function Signed-off-by: Riku Voipio <[email protected]> Signed-off-by: Michal Marek <[email protected]>

2015-04-22modpost: don't emit section mismatch warnings for compiler optimizationsPaul Gortmaker1-0/+21
Currently an allyesconfig build [gcc-4.9.1] can generate the following: WARNING: vmlinux.o(.text.unlikely+0x3864): Section mismatch in reference from the function cpumask_empty.constprop.3() to the variable .init.data:nmi_ipi_mask which comes from the cpumask_empty usage in arch/x86/kernel/nmi_selftest.c. Normally we would not see a symbol entry for cpumask_empty since it is: static inline bool cpumask_empty(const struct cpumask *srcp) however in this case, the variant of the symbol gets emitted when GCC does constant propagation optimization. Fix things up so that any locally optimized constprop variants don't warn when accessing variables that live in the __init sections.
