2011-04-20drm/nouveau: fix notifier memory corruption bugMarcin Slusarz1-2/+2
nouveau_bo_wr32 expects offset to be in words, but we pass value in bytes, so after commit 73412c3854c877e5f37ad944ee8977addde4d35a ("drm/nouveau: allocate kernel's notifier object at end of block") we started to overwrite some memory after notifier buffer object (previously m2mf_ntfy was always 0, so it didn't matter it was a value in bytes).

2011-04-20PM: Add missing syscore_suspend() and syscore_resume() callsRafael J. Wysocki4-1/+22
Device suspend/resume infrastructure is used not only by the suspend and hibernate code in kernel/power, but also by APM, Xen and the kexec jump feature. However, commit 40dc166cb5dddbd36aa4ad11c03915ea (PM / Core: Introduce struct syscore_ops for core subsystems PM) failed to add syscore_suspend() and syscore_resume() calls to that code, which generally leads to breakage when the features in question are used. To fix this problem, add the missing syscore_suspend() and syscore_resume() calls to arch/x86/kernel/apm_32.c, kernel/kexec.c and drivers/xen/manage.c. Signed-off-by: Rafael J.

We are currently using this flag to check whether it's safe to call into ->request_fn(). If it is set, we punt to kblockd. But we get a lot of false positives and excessive punts to kblockd, which hurts performance. The only real abuser of this infrastructure is SCSI. So export the async queue run and convert SCSI over to use that.
