Paravirt ops pmd_update/pmd_update_defer/pmd_set_at. Not all might be necessary (vmware needs pmd_update, Xen needs set_pmd_at, nobody needs pmd_update_defer), but this is to keep full simmetry with pte paravirt ops, which looks cleaner and simpler from a common code POV.

2011-01-13mm: unify module_alloc code for vmallocDavid Rientjes1-13/+4
Four architectures (arm, mips, sparc, x86) use __vmalloc_area() for module_init(). Much of the code is duplicated and can be generalized in a globally accessible function, __vmalloc_node_range(). __vmalloc_node() now calls into __vmalloc_node_range() with a range of [VMALLOC_START, VMALLOC_END) for functionally equivalent behavior. Each architecture may then use __vmalloc_node_range() directly to remove the duplication of code.

2011-01-13x86: support XZ-compressed kernelLasse Collin5-7/+11
This integrates the XZ decompression code to the x86 pre-boot code. mkpiggy.c is updated to reserve about 32 KiB more buffer safety margin for kernel decompression. It is done unconditionally for all decompressors to keep the code simpler. The XZ decompressor needs around 30 KiB of heap, so the heap size is increased to 32 KiB on both x86-32 and x86-64. Documentation/x86/boot.txt is updated to list the XZ magic number. With the x86 BCJ filter in XZ, XZ-compressed x86 kernel tends to be a few percent smaller than the equivalent LZMA-compressed kernel. Signed-off-by: Lasse Collin <[email protected]> Cc: "H.

2011-01-12cpuidle/x86/perf: fix power:cpu_idle double end events and throw cpu_idle ↵Thomas Renninger3-12/+4
events from the cpuidle layer Currently intel_idle and acpi_idle driver show double cpu_idle "exit idle" events -> this patch fixes it and makes cpu_idle events throwing less complex. It also introduces cpu_idle events for all architectures which use the cpuidle subsystem, namely: - arch/arm/mach-at91/cpuidle.c - arch/arm/mach-davinci/cpuidle.c - arch/arm/mach-kirkwood/cpuidle.c - arch/arm/mach-omap2/cpuidle34xx.c - arch/drivers/acpi/processor_idle.c (for all cases, not only mwait) - arch/x86/kernel/process.c (did throw events before, but was a mess) - drivers/idle/intel_idle.c (did throw events before) Convention should be: Fire cpu_idle events inside the current pm_idle function (not somewhere down the the callee tree) to keep things easy. Current possible pm_idle functions in X86: c1e_idle, poll_idle, cpuidle_idle_call, mwait_idle, default_idle -> this is really easy is now. This affects userspace: The type field of the cpu_idle power event can now direclty get mapped to: /sys/devices/system/cpu/cpuX/cpuidle/stateX/{name,desc,usage,time,...} instead of throwing very CPU/mwait specific values. This change is not visible for the intel_idle driver. For the acpi_idle driver it should only be visible if the vendor misses out C-states in his BIOS. Another (perf timechart) patch reads out cpuidle info of cpu_idle events from: /sys/.../cpuidle/stateX/*, then the cpuidle events are mapped to the correct C-/cpuidle state again, even if e.g. vendors miss out C-states in their BIOS and for example only export C1 and C3. -> everything is fine.

2011-01-12ACPI, intel_idle: Cleanup idle= internal variablesThomas Renninger2-18/+11
Having four variables for the same thing: idle_halt, idle_nomwait, force_mwait and boot_option_idle_overrides is rather confusing and unnecessary complex. if idle= boot param is passed, only set up one variable: boot_option_idle_overrides Introduces following functional changes/fixes: - intel_idle driver does not register if any idle=xy boot param is passed. - processor_idle.c will also not register a cpuidle driver and get active if idle=halt is passed. Before a cpuidle driver with one (C1, halt) state got registered Now the default_idle function will be used which finally uses the same idle call to enter sleep state (safe_halt()), but without registering a whole cpuidle driver. That means idle= param will always avoid cpuidle drivers to register with one exception (same behavior as before): idle=nomwait may still register acpi_idle cpuidle driver, but C1 will not use mwait, but hlt. This can be a workaround for IO based deeper sleep states where C1 mwait causes problems.

2011-01-12KVM: MMU: Fix incorrect direct page write protection due to ro host pageAvi Kivity1-3/+3
If KVM sees a read-only host page, it will map it as read-only to prevent breaking a COW. However, if the page was part of a large guest page, KVM incorrectly extends the write protection to the entire large page frame instead of limiting it to the normal host page. This results in the instantiation of a new shadow page with read-only access. If this happens for a MOVS instruction that moves memory between two normal pages, within a single large page frame, and mapped within the guest as a large page, and if, in addition, the source operand is not writeable in the host (perhaps due to KSM), then KVM will instantiate a read-only direct shadow page, instantiate an spte for the source operand, then instantiate a new read/write direct shadow page and instantiate an spte for the destination operand. Since these two sptes are in different shadow pages, MOVS will never see them at the same time and the guest will not make progress. Fix by mapping the direct shadow page read/write, and only marking the host page read-only. Signed-off-by: Avi Kivity <[email protected]>

There are many approaches to achieve this but the most direct is to simply avoid trapping the HLT instruction which lets the guest directly execute the instruction putting the processor to sleep.
