      [PATCH] Fix insta-reboot with "i386: Relocatable kernel support" · c6b33cc4
      Segher Boessenkool authored 
      Commit 968de4f0 ("i386: Relocatable
kernel support") caused problems for people with old binutils versions
that didn't mark ".text.*" sections automatically allocated.

So we should use .section command to specifically mark .text.head
section as AX (allocatable and executable) to solve the problem.

This should be unnecessary with binutils 2.15 and later, which is
already three years old, but it doesn't hurt supporting older toolchains
where possible.

      [PATCH] selinux: fix selinux_netlbl_inode_permission() locking · 9883a13c
      Parag Warudkar authored 
      do not call a sleeping lock API in an RCU read section.
lock_sock_nested can sleep, its BH counterpart doesn't.
selinux_netlbl_inode_permission() needs to use the BH counterpart
unconditionally.

Compile tested.

From: Ingo Molnar <mingo@elte.hu>

added BH disabling, because this function can be called from non-atomic
contexts too, so a naked bh_lock_sock() would be deadlock-prone.

Boot-tested the resulting kernel.

      [PATCH] cfq-iosched: merging problem · ec8acb69
      Jens Axboe authored 
      Two issues:

- The final return 1 should be a return 0, otherwise comparing cfqq is
  a noop.

- bio_sync() only checks the sync flag, while rq_is_sync() checks both
  for READ and sync. The latter is what we want. Expand the bio check
  to include reads, and relax the restriction to allow merging of async
  io into sync requests.

In the future we want to clean up the SYNC logic, right now it means
both sync request (such as READ and O_DIRECT WRITE) and unplug-on-issue.
Leave that for later.

      [PATCH] libata: fix combined mode · dc3c3377
      Alan authored 
      This is a slight variant on the patch I posted December 16th to fix
libata combined mode handling. The only real change is that we now
correctly also reserve BAR1,2,4. That is basically a neatness issue.

Jeff was unhappy about two things

1. That it didn't work in the case of one channel native one channel
legacy.

This is a silly complaint because the SFF layer in libata doesn't handle
this case yet anyway.

2. The case where combined mode is in use and IDE=n.

In this case the libata quirk code reserves the resources in question
correctly already.

Once the combined mode stuff is redone properly (2.6.21) then the entire
mess turns into a single pci_request_regions() for all cases and all the
ugly resource hackery goes away.

I'm sending this now rather than after running full test suites so that
it can get the maximal testing in a short time. I'll be running tests on
this after lunch.
