2006-03-22[PATCH] hugepage: is_aligned_hugepage_range() cleanupDavid Gibson
Quite a long time back, prepare_hugepage_range() replaced is_aligned_hugepage_range() as the callback from mm/mmap.c to arch code to verify if an address range is suitable for a hugepage mapping. is_aligned_hugepage_range() stuck around, but only to implement prepare_hugepage_range() on archs which didn't implement their own. Most archs (everything except ia64 and powerpc) used the same implementation of is_aligned_hugepage_range(). On powerpc, which implements its own prepare_hugepage_range(), the custom version was never used. In addition, "is_aligned_hugepage_range()" was a bad name, because it suggests it returns true iff the given range is a good hugepage range, whereas in fact it returns 0-or-error (so the sense is reversed). This patch cleans up by abolishing is_aligned_hugepage_range(). Instead prepare_hugepage_range() is defined directly. Most archs use the default version, which simply checks the given region is aligned to the size of a hugepage. ia64 and powerpc define custom versions. The ia64 one simply checks that the range is in the correct address space region in addition to being suitably aligned. The powerpc version (just as previously) checks for suitable addresses, and if necessary performs low-level MMU frobbing to set up new areas for use by hugepages. No libhugetlbfs testsuite regressions on ppc64 (POWER5 LPAR). Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Zhang Yanmin <yanmin.zhang@intel.com> Cc: "David S.

2006-03-22[PATCH] Uninline sys_mmap common code (reduce binary size)Michael Buesch
Remove the inlining of the new vs old mmap system call common code. This reduces the size of the resulting vmlinux for defconfig as follows: mb@pc1:~/develop/git/linux-2.6$ size vmlinux.mmap* text data bss dec hex filename 3303749 521524 186564 4011837 3d373d vmlinux.mmapinline 3303557 521524 186564 4011645 3d367d vmlinux.mmapnoinline The new sys_mmap2() has also one function call overhead removed, now.

2006-03-22[PATCH] remove set_page_count() outside mm/Nick Piggin
set_page_count usage outside mm/ is limited to setting the refcount to 1. Remove set_page_count from outside mm/, and replace those users with init_page_count() and set_page_refcounted(). This allows more debug checking, and tighter control on how code is allowed to play around with page->_count.

2006-03-22[PATCH] on_each_cpu(): disable local interruptsAndrew Morton
When on_each_cpu() runs the callback on other CPUs, it runs with local interrupts disabled. So we should run the function with local interrupts disabled on this CPU, too. And do the same for UP, so the callback is run in the same environment on both UP and SMP. (strictly it should do preempt_disable() too, but I think local_irq_disable is sufficiently equivalent). Also uninlines on_each_cpu(). softirq.c was the most appropriate file I could find, but it doesn't seem to justify creating a new file. Oh, and fix up that comment over (under?) x86's smp_call_function(). It drives me nuts. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-03-21[CRYPTO] aes: Fixed array boundary violationDavid McCullough
The AES setkey routine writes 64 bytes to the E_KEY area even though there are only 60 bytes there. It is in fact safe since E_KEY is immediately follwed by D_KEY which is initialised afterwards. However, doing this may trigger undefined behaviour and makes Coverity unhappy. So by combining E_KEY and D_KEY into one array we sidestep this issue altogether.
