2010-08-28mm: fix hang on anon_vma->root->lockHugh Dickins1-3/+16
After several hours, kbuild tests hang with anon_vma_prepare() spinning on a newly allocated anon_vma's lock - on a box with CONFIG_TREE_PREEMPT_RCU=y (which makes this very much more likely, but it could happen without). The ever-subtle page_lock_anon_vma() now needs a further twist: since anon_vma_prepare() and anon_vma_fork() are liable to change the ->root of a reused anon_vma structure at any moment, page_lock_anon_vma() needs to check page_mapped() again before succeeding, otherwise page_unlock_anon_vma() might address a different root->lock.

2010-08-26nfsd4: fix downgrade/lock logicJ. Bruce Fields2-16/+21
If we already had a RW open for a file, and get a readonly open, we were piggybacking on the existing RW open. That's inconsistent with the downgrade logic which blows away the RW open assuming you'll still have a readonly open. Also, make sure there is a readonly or writeonly open available for locking, again to prevent bad behavior in downgrade cases when any RW open may be lost. Signed-off-by: J.

2010-08-26amd64_edac: Do not report error overflow as a separate errorBorislav Petkov2-13/+2
When the Overflow MCi_STATUS bit is set, EDAC reports the lost error with a "no information available" message which often puzzles users parsing the dmesg. This doesn't make much sense since this error has been lost anyway so no need for reporting it separately. Thus, report the overflow bit setting in the MCE dump instead. While at it, remove reporting of MiscV and ErrorEnable (en) which are superfluous. Now it looks like this: [ 1501.650024] MC4_STATUS: Corrected error, other errors lost: yes, CPU context corrupt: no, CECC Error [ 1501.666887] Northbridge Error, node 2 Signed-off-by: Borislav Petkov <[email protected]>

Fix DSM/TRIM commands in sata_mv (v2). These need to be issued using old-school "BM DMA", rather than via the EDMA host queue. Since the chips don't have proper BM DMA status, we need to be more careful with setting the ATA_DMA_INTR bit, since DSM/TRIM often has a long delay between "DMA complete" and "command complete". GEN_I chips don't have BM DMA, so no TRIM for them. Signed-off-by: Mark Lord <[email protected]> Signed-off-by: Jeff Garzik <[email protected]> Cc: [email protected]

Just scrubbing some warnings so I can see real problem ones in the build noise. For 32bit we need to coax gcc politely into believing we really honestly intend to the casts.

Commit 8bf0223ed515be24de0c671eedaff49e78bebc9c (hwmon, k8temp: Fix temperature reporting for ASB1 processor revisions) fixed temperature reporting for ASB1 CPUs. But those CPU models (model 0x6b, 0x6f, 0x7f) were packaged both as AM2 (desktop) and ASB1 (mobile). Thus the commit leads to wrong temperature reporting for AM2 CPU parts. The solution is to determine the package type for models 0x6b, 0x6f, 0x7f. This is done using BrandId from CPUID Fn8000_0001_EBX[15:0].

We used to use i_head_snapc to keep track of which snapc the current epoch of dirty data was dirtied under. It is used by queue_cap_snap to set up the cap_snap. However, since we queue cap snaps for any dirty caps, not just for dirty file data, we need to keep a valid i_head_snapc anytime we have dirty|flushing caps.
