All kthreads being created from a single helper task, they all use memory from a single node for their kernel stack and task struct. This patch suite creates kthread_create_on_cpu(), adding a 'cpu' parameter to parameters already used by kthread_create(). This parameter serves in allocating memory for the new kthread on its memory node if available. Users of this new function are : ksoftirqd, kworker, migration, pktgend...

2011-01-25percpu: align percpu readmostly subsection to cachelineTejun Heo1-1/+1
Currently percpu readmostly subsection may share cachelines with other percpu subsections which may result in unnecessary cacheline bounce and performance degradation. This patch adds @cacheline parameter to PERCPU() and PERCPU_VADDR() linker macros, makes each arch linker scripts specify its cacheline size and use it to align percpu subsections.

Both commits 0a3d763f1a68 ("ptrace: cleanup arch_ptrace() on um") and 9b05a69e0534 ("ptrace: change signature of arch_ptrace()") broke the um build. This patch fixes the issues. 0a3d763f1a68 introduced the undeclared variable "datavp".

2010-10-26uml: define CONFIG_NO_DMAFUJITA Tomonori1-112/+0
I think that it's better to detect DMA misuse at build time rather than calling BUG_ON. Architectures that can't do DMA need to define CONFIG_NO_DMA. Thanks to Sam Ravnborg for explaining how CONFIG_NO_DMA and CONFIG_HAS_DMA work: http://marc.info/?l=linux-kernel&m=128359913825550&w=2 HAS_DMA is defined like this: config HAS_DMA boolean depends on !NO_DMA default y So to set HAS_DMA to true an arch should do: 1) Do not define NO_DMA 2) Define NO_DMA abd set it to 'n' Must archs - including um - used principle 1). In the um case we want to say that we do NOT have any DMA. This can be done in two ways. a) define NO_DMA and set it to 'y' b) redefine HAS_DMA and set it to 'n'. The patch you provided used principle b) where other archs use principle a). So I suggest you should use principle a) for um too.

2010-08-11dma-mapping: remove dma_is_consistent APIFUJITA Tomonori1-1/+0
Architectures implement dma_is_consistent() in different ways (some misinterpret the definition of API in DMA-API.txt). So it hasn't been so useful for drivers. We have only one user of the API in tree. Unlikely out-of-tree drivers use the API. Even if we fix dma_is_consistent() in some architectures, it doesn't look useful at all. It was invented long ago for some old systems that can't allocate coherent memory at all. It's better to export only APIs that are definitely necessary for drivers. Let's remove this API.

After tightening up the types passed to set_64bit(), the cast to (phys_t *) triggers a warning apparently because phys_t is defined as "unsigned long" when building on 64 bits; however, u64 is defined as "unsigned long long".

Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT, PTRACE_KILL and PTRACE_SINGLESTEP. This implies defining arch_has_single_step in <asm/ptrace.h> and implementing the user_enable_single_step and user_disable_single_step functions, which also causes the breakpoint information to be cleared on fork, which could be considered a bug fix. Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which it previously wasn't which is consistent with all architectures using the modern ptrace code. XXX: I'm not sure arch_has_single_step() is placed in the exactly correct location, please verify in which of the ptrace headers it should really be.

2010-02-20MM: Pass a PTE pointer to update_mmu_cache() rather than the PTE itselfRussell King1-1/+1
On VIVT ARM, when we have multiple shared mappings of the same file in the same MM, we need to ensure that we have coherency across all copies. We do this via make_coherent() by making the pages uncacheable. This used to work fine, until we allowed highmem with highpte - we now have a page table which is mapped as required, and is not available for modification via update_mmu_cache(). Ralf Beache suggested getting rid of the PTE value passed to update_mmu_cache(): On MIPS update_mmu_cache() calls __update_tlb() which walks pagetables to construct a pointer to the pte again. Passing a pte_t * is much more elegant. Maybe we might even replace the pte argument with the pte_t? Ben Herrenschmidt would also like the pte pointer for PowerPC: Passing the ptep in there is exactly what I want. I want that -instead- of the PTE value, because I have issue on some ppc cases, for I$/D$ coherency, where set_pte_at() may decide to mask out the _PAGE_EXEC. So, pass in the mapped page table pointer into update_mmu_cache(), and remove the PTE value, updating all implementations and call sites to suit.

2009-07-27mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()Benjamin Herrenschmidt2-5/+5
mm: Pass virtual address to [__]p{te,ud,md}_free_tlb() Upcoming paches to support the new 64-bit "BookE" powerpc architecture will need to have the virtual address corresponding to PTE page when freeing it, due to the way the HW table walker works. Basically, the TLB can be loaded with "large" pages that cover the whole virtual space (well, sort-of, half of it actually) represented by a PTE page, and which contain an "indirect" bit indicating that this TLB entry RPN points to an array of PTEs from which the TLB can then create direct entries. Thus, in order to invalidate those when PTE pages are deleted, we need the virtual address to pass to tlbilx or tlbivax instructions. The old trick of sticking it somewhere in the PTE page struct page sucks too much, the address is almost readily available in all call sites and almost everybody implemets these as macros, so we may as well add the argument everywhere.

2009-07-09linker script: unify usage of discard definitionTejun Heo1-5/+0
Discarded sections in different archs share some commonality but have considerable differences. This led to linker script for each arch implementing its own /DISCARD/ definition, which makes maintaining tedious and adding new entries error-prone. This patch makes all linker scripts to move discard definitions to the end of the linker script and use the common DISCARDS macro. As ld uses the first matching section definition, archs can include default discarded sections by including them earlier in the linker script. ia64 is notable because it first throws away some ia64 specific subsections and then include the rest of the sections into the final image, so those sections must be discarded before the inclusion. defconfig compile tested for x86, x86-64, powerpc, powerpc64, ia64, alpha, sparc, sparc64 and s390.

2009-06-12module: merge module_alloc() finallyAmerigo Wang1-1/+6
As Christoph Hellwig suggested, module_alloc() actually can be unified for i386 and x86_64 (of course, also UML). Signed-off-by: WANG Cong <[email protected]> Cc: Christoph Hellwig <[email protected]> Cc: 'Ingo Molnar' <[email protected]> Signed-off-by: Rusty Russell <[email protected]>
2009-06-11asm-generic: rename page.h and uaccess.hArnd Bergmann1-1/+1
The current asm-generic/page.h only contains the get_order function, and asm-generic/uaccess.h only implements unaligned accesses. This renames the file to getorder.h and uaccess-unaligned.h to make room for new page.h and uaccess.h file that will be usable by all simple (e.g. nommu) architectures.

2009-03-02tracing: make CALLER_ADDRx overwriteableUwe Kleine-Koenig1-0/+1
The current definition of CALLER_ADDRx isn't suitable for all platforms. E.g. for ARM __builtin_return_address(N) doesn't work for N > 0 and AFAIK for powerpc there are no frame pointers needed to have a working __builtin_return_address. This patch allows defining the CALLER_ADDRx macros in <asm/ftrace.h> and let these take precedence. Because now <asm/ftrace.h> is included unconditionally in <linux/ftrace.h> all archs that don't already had this include get an empty one for free.
