[PATCH 6/7] drm: use workqueue instead of slow-work
Workqueue can now handle high concurrency. Convert drm_crtc_helper to use system_nrt_wq instead of slow-work. The conversion is mostly straight forward. One difference is that drm_helper_hpd_irq_event() no longer blocks and can be called from any context. Signed-off-by: Tejun Heo <tj(a)> Cc: David Air... 20 Jul 2010 16:52
[PATCH] cfq: improve fsync performance for small files
Fsync performance for small files achieved by cfq on high-end disks is lower than what deadline can achieve, due to idling introduced between the sync write happening in process context and the journal commit. Moreover, when competing with a sequential reader, a process writing small files and fsync-ing them is s... 20 Jul 2010 16:52
[PATCH] x86/hugetlb: use set_pmd for huge pte operations
From: Dave McCracken <dave.mccracken(a)> On x86, a huge pte is logically a pte, but structurally a pmd. Among other issues, pmds and ptes overload some flags for multiple uses (PAT vs PSE), so it is necessary to know which structural level a pagetable entry is in order interpret it properly. When huge... 20 Jul 2010 16:52

[PATCH] vga16fb: refuse to load in face of other driver controlling primary card
We don't want vga16fb to mess with hardware initialized by other driver. Detect it and refuse to load. It fixes nouveau interrupt storm on some machines.

[PATCH 01/10] x86, xsave: do not include asm/i387.h in asm/xsave.h
There are no dependencies to asm/i387.h.

[PATCH 06/10] x86, xsave: do not initialize xsave in fpu_init()
As xsave also supports other than fpu features, it should be initialized independently of the fpu. This patch moves this out of fpu initialization.
