2007-02-23make ppc64 current preempt-safeHugh Dickins
Repeated -j20 kernel builds on a G5 Quad running an SMP PREEMPT kernel would often collapse within a day, some exec failing with "Bad address". In each case examined, load_elf_binary was doing a kernel_read, but generic_file_aio_read's access_ok saw current->thread.fs.seg as USER_DS instead of KERNEL_DS. objdump of filemap.o shows gcc 4.1.0 emitting "mr r5,r13 ... ld r9,416(r5)" here for get_paca()->__current, instead of the expected and much more usual "ld r9,416(r13)"; I've seen other gcc4s do the same, but perhaps not gcc3s. So, if the task is preempted and rescheduled on a different cpu in between the mr and the ld, r5 will be looking at a different paca_struct from the one it's now on, pick up the wrong __current, and perhaps the wrong seg. Presumably much worse could happen elsewhere, though that split is rare. Other architectures appear to be safe (x86_64's read_pda is more limiting than get_paca), but ppc64 needs to force "current" into one instruction.

2006-12-16[PATCH] m32r: make userspace headers platform-independentHirokazu Takata
The m32r kernel 2.6.18-rc1 or after cause build errors of "unknown isa configuration" for userspace application programs, such as glibc, gdb, etc. This is because the recent kernel do not include linux/config.h not to expose kernel headers for userspace. To fix the above compile errors, this patch fixes two headers ptrace.h and sigcontext.h for m32r and makes them platform-independent.

2006-11-18[PATCH] fix UFS superblock alignment issuesEric Sandeen
ufs2 fails to mount on x86_64, claiming bad magic. This is because ufs_super_block_third's fs_un1 member is padded out by 4 bytes for 8-byte alignment, pushing down the rest of the struct. Forcing this to be packed solves it. I took a quick look over other on-disk structures and didn't immediately find other problems. I was able to mount & ls a populated ufs2 filesystem w/ this change.

When I added the robust futex syscall entries I forgot to bump NR_SYSCALLS.

2006-11-03[PATCH] vmscan: Fix temp_priority raceMartin Bligh
The temp_priority field in zone is racy, as we can walk through a reclaim path, and just before we copy it into prev_priority, it can be overwritten (say with DEF_PRIORITY) by another reclaimer. The same bug is contained in both try_to_free_pages and balance_pgdat, but it is fixed slightly differently. In balance_pgdat, we keep a separate priority record per zone in a local array. In try_to_free_pages there is no need to do this, as the priority level is the same for all zones that we reclaim from. Impact of this bug is that temp_priority is copied into prev_priority, and setting this artificially high causes reclaimers to set distress artificially low. They then fail to reclaim mapped pages, when they are, in fact, under severe memory pressure (their priority may be as low as 0). This causes the OOM killer to fire incorrectly. From: Andrew Morton <akpm@osdl.org> __zone_reclaim() isn't modifying zone->prev_priority. But zone->prev_priority is used in the decision whether or not to bring mapped pages onto the inactive list. Hence there's a risk here that __zone_reclaim() will fail because zone->prev_priority ir large (ie: low urgency) and lots of mapped pages end up stuck on the active list. Fix that up by decreasing (ie making more urgent) zone->prev_priority as __zone_reclaim() scans the zone's pages. This bug perhaps explains why ZONE_RECLAIM_PRIORITY was created. It should be possible to remove that now, and to just start out at DEF_PRIORITY?

2006-11-03[PATCH] __div64_32 for 31 bit.Martin Schwidefsky
The clocksource infrastructure introduced with commit ad596171ed635c51a9eef829187af100cbf8dcf7 broke 31 bit s390. The reason is that the do_div() primitive for 31 bit always had a restriction: it could only divide an unsigned 64 bit integer by an unsigned 31 bit integer. The clocksource code now uses do_div() with a base value that has the most significant bit set. The result is that clock->cycle_interval has a funny value which causes the linux time to jump around like mad. The solution is "obvious": implement a proper __div64_32 function for 31 bit s390.

2006-10-13zone_reclaim: dynamic slab reclaimChristoph Lameter
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=0ff38490c836dc379ff7ec45b10a15a662f4e5f6 Currently one can enable slab reclaim by setting an explicit option in /proc/sys/vm/zone_reclaim_mode. Slab reclaim is then used as a final option if the freeing of unmapped file backed pages is not enough to free enough pages to allow a local allocation. However, that means that the slab can grow excessively and that most memory of a node may be used by slabs. We have had a case where a machine with 46GB of memory was using 40-42GB for slab. Zone reclaim was effective in dealing with pagecache pages. However, slab reclaim was only done during global reclaim (which is a bit rare on NUMA systems). This patch implements slab reclaim during zone reclaim. Zone reclaim occurs if there is a danger of an off node allocation. At that point we 1. Shrink the per node page cache if the number of pagecache pages is more than min_unmapped_ratio percent of pages in a zone. 2. Shrink the slab cache if the number of the nodes reclaimable slab pages (patch depends on earlier one that implements that counter) are more than min_slab_ratio (a new /proc/sys/vm tunable). The shrinking of the slab cache is a bit problematic since it is not node specific. So we simply calculate what point in the slab we want to reach (current per node slab use minus the number of pages that neeed to be allocated) and then repeately run the global reclaim until that is unsuccessful or we have reached the limit. I hope we will have zone based slab reclaim at some point which will make that easier. The default for the min_slab_ratio is 5% Also remove the slab option from /proc/sys/vm/zone_reclaim_mode.

This brings i386 asm/unistd.h into consistency with other architectures by not exporting functionality which is not necessary. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-09-14[ARM] 3785/1: S3C2412: Fix idle code as default uses wrong clocksBen Dooks
Patch from Ben Dooks Fix the idle code on the s3c2412 as the default code is using bits in the CLKCON register that are no-longer there. Provide an override for the idle code, and ensure that the power configuration is set to allow idle instead of stop or sleep.

2006-09-13[PATCH] headers_check: fix userspace build of asm-mips/page.hDavid Woodhouse
MIPS asm/page.h unconditionally includes <asm-generic/memory_model.h>, which doesn't exist in userspace. Move an #endif /* __KERNEL__ */ down a few lines to prevent that. Also, remove the broken definition of PAGE_SIZE which is never going to be correct -- in the absence of PAGE_SIZE, non-broken userspace will fall back to using sysconf() or getpagesize() instead.

2006-09-13[PATCH] headers_check: don't expose PFN stuff to userspace in <asm-i386/setup.h>David Woodhouse
The header file <linux/pfn.h> doesn't exist in userspace and probably shouldn't -- but it's used unconditionally in <asm-i386/setup.h>. Protect it with #ifdef __KERNEL__ and move setup.h from $(header-y) to $(unifdef-y) in Kbuild accordingly.

2006-09-13[PATCH] headers_check: move kernel-only #includes within <asm-i386/elf.h>David Woodhouse
Some files which don't exist in userspace were being included unconditionally in asm-i386/elf.h. Move the offending #includes down a few lines so that they're protected by #ifdef __KERNEL__ In fact, we probably want to kill off all userspace use of asm/elf.h -- but we aren't there yet, so we should at least make it possible to include it for now.
