There is a race between ext4 buffer write and direct_IO read with

PageWriteback flag during end_io time but will do

Note that this is just a bandaid fix. The fundamental issue is that we
clear PageWriteback flag before we really complete an IO, which is

13 years agodrm/i915: set GFX_MODE to pre-Ivybridge default value even on Ivybridge
Jesse Barnes [Fri, 12 Aug 2011 22:28:32 +0000 (15:28 -0700)]
drm/i915: set GFX_MODE to pre-Ivybridge default value even on Ivybridge

Prior to Ivybridge, the GFX_MODE would default to 0x800, meaning that
MI_FLUSH would flush the TLBs in addition to the rest of the caches
indicated in the MI_FLUSH command.  However starting with Ivybridge, the
register defaults to 0x2800 out of reset, meaning that to invalidate the
TLB we need to use PIPE_CONTROL.  Since we're not doing that yet, go
back to the old default so things work.

handlers to adopt the differing macros for system call and interrupt

13 years agom68k: reorganize Kconfig options to improve mmu/non-mmu selections
Greg Ungerer [Mon, 20 Jun 2011 05:49:09 +0000 (15:49 +1000)]
m68k: reorganize Kconfig options to improve mmu/non-mmu selections

The current mmu and non-mmu Kconfig files can be merged to form
a more general selection of options. The current break up of options
is due to the simple brute force merge from the m68k and m68knommu
arch directories.

Many of the options are not at all specific to having the MMU enabled
or not. They are actually associated with a particular CPU type or
platform type.

Ultimately as we support all processors with the MMU disabled we need
many of these options to be selectable without the MMU option enabled.
And likewise some of the ColdFire processors, which currently are only
supported with the MMU disabled, do have MMU hardware, and will need
to have options selected on CPU type, not MMU disabled.

This patch removes the old mmu and non-mmu Kconfigs and instead breaks
up the configuration into four areas: cpu, machine, bus, devices.

The Kconfig.cpu lists all the options associated with selecting a CPU,
and includes options specific to each CPU type as well.

Kconfig.machine lists all options associated with selecting a machine
type. Almost always the machines selectable is restricted by the chosen
CPU.

Kconfig.bus contains options associated with selecting bus types on the
various machine types. That includes PCI bus, PCMCIA bus, etc.

Kconfig.devices contains options for drivers and driver associated
options.
