ext2: report metadata errors during fsync
When an IO error happens while writing metadata buffers, we should better
report it and call ext2_error since the filesystem is probably no longer
consistent. Sometimes such IO errors happen while flushing thread does
background writeback, the buffer gets later evicted from memory, and thus
the only trace of the error remains as AS_EIO bit set in blockdevice's
mapping. So we check this bit in ext2_fsync and report the error although
we cannot be really sure which buffer we failed to write.

intelfb: fix setting of active pipe with LVDS displays
The intelfb driver sets color map depending on currently active pipe.
However, if an LVDS display is attached (like in laptop) the active pipe
variable is never set. The default value is PIPE_A and can be wrong. Set
up the pipe variable during driver initialization after hardware state was
read.
Also, the detection of the active display (and hence the pipe) is wrong.
The pipes are assigned to so called planes. Both pipes are always enabled
on my laptop but only one plane is enabled (the plane A for the CRT or the
plane B for the LVDS). Change active pipe detection code to take into
account a status of the plane assigned to each pipe.
The problem is visible in the 8 bpp mode if colors above 15 are used. The
first 16 color entries are displayed correctly.

autofs4: eliminate d_unhashed in path walk checks
We unhash the dentry (in a subsequent patch) in ->d_revalidate() in order
to send mount requests to ->lookup(). But then we can not rely on
d_unhased() to give reliable results because it may be called at any time
by any code path. The d_unhashed() function is used by __simple_empty()
in the path walking callbacks but autofs mount point dentrys should have
no directories at all so a list_empty() on d_subdirs should be (and is)
sufficient.

Fix node-oriented allocation handling in oom-kill.c I myself think of this
as a bugfix not as an ehnancement.
In these days, things are changed as
- alloc_pages() eats nodemask as its arguments, __alloc_pages_nodemask().
- mempolicy don't maintain its own private zonelists.
(And cpuset doesn't use nodemask for __alloc_pages_nodemask())
So, current oom-killer's check function is wrong.
This patch does
- check nodemask, if nodemask && nodemask doesn't cover all
node_states[N_HIGH_MEMORY], this is CONSTRAINT_MEMORY_POLICY.
- Scan all zonelist under nodemask, if it hits cpuset's wall
this faiulre is from cpuset.
And
- modifies the caller of out_of_memory not to call oom if __GFP_THISNODE.
This doesn't change "current" behavior. If callers use __GFP_THISNODE
it should handle "page allocation failure" by itself.
- handle __GFP_NOFAIL+__GFP_THISNODE path.
This is something like a FIXME but this gfpmask is not used now.
