[PATCH] m32r: make userspace headers platform-independent

2006-12-17T00:20:48Z

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.

[PATCH] NETFILTER: Honour source routing for LVS-NAT

2006-12-02T00:12:35Z

For policy routing, packets originating from this machine itself may be routed differently to packets passing through. We want this packet to be routed as if it came from this machine itself. So re-compute the routing information using ip_route_me_harder(). This patch is derived from work by Ken Brownfield This patch (-stable version) also includes commit b4c4ed175ff0ee816df48571cfa9b73f521964b6 ([NETFILTER]: add type parameter to ip_route_me_harder), which is a precondition for the fix.

[PATCH] fix UFS superblock alignment issues

2006-11-19T03:28:00Z

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.

[PATCH] SPARC: Fix missed bump of NR_SYSCALLS.

2006-11-19T03:27:59Z

When I added the robust futex syscall entries I forgot to bump NR_SYSCALLS. This is an easy mistake to make because NR_SYSCALLS lived in entry.S which is nowhere near unistd.h or syscalls.S, so while we're here move it's definition into unistd.h so this is unlikely to ever happen again.

[PATCH] SPARC64: Fix futex_atomic_cmpxchg_inatomic implementation.

2006-11-19T03:27:58Z

I copied the logic from ll/sc arch implementations, but that was wrong and makes no sense at all. Just do a straight compare-exchange instruction, just like x86. Based upon bug reports from Dennis Gilmore and Fabio Massimo. Signed-off-by: David S. Miller Signed-off-by: Chris Wright

[PATCH] vmscan: Fix temp_priority race

2006-11-04T01:33:50Z

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 __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?

[PATCH] SERIAL: Fix oops when removing suspended serial port

2006-11-04T01:33:46Z

[SERIAL] Fix oops when removing suspended serial port A serial card might have been removed when the system is resumed. This results in a suspended port being shut down, which results in the ports shutdown method being called twice in a row. This causes BUGs. Avoid this by tracking the suspended state separately from the initialised state.
