[PATCH] selinux: fix selinux_netlbl_inode_permission() locking

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.

added BH disabling, because this function can be called from non-atomic

[PATCH] cfq-iosched: merging problem

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.

[PATCH] libata: fix combined mode

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.

[PATCH] PIIX/SLC90E66: PIO mode fallback fix

The fallback to PIO mode in the hwif->dma_check() handler doesn't work in
the Intel PIIX and SMsC SLC90E66 IDE drivers because:

- config_drive_for_dma() calls the hwif->speedproc() handler with a wrong
  mode number (unbiased by XFER_PIO_0) in case of the PIO fallback;

- hwif->tuneproc() handler doesn't really set the drive's own speed (this
  is not fixed as yet).

David Brownell [Sat, 30 Dec 2006 00:48:39 +0000 (16:48 -0800)]
[PATCH] SPI: define null tx_buf to mean "shift out zeroes"

Some issues were recently turned up with the current specification of what
it means for spi_transfer.tx_buf to be null, as part of transfers which are
(from the SPI protocol driver perspective) pure reads.

Specifically, that it seems better to change the TX behaviour there from
"undefined" to "will shift zeroes".  This lets protocol drivers (like the
ads7846 driver) depend on that behavior.  It's what most controller drivers
in the tree are already doing (with one exception and one case of driver
wanting-to-oops), it's what Microwire hardware will necessarily be doing,
and it removes an issue whereby certain security audits would need to
define such a value anyway as part of removing covert channels.

This patch changes the specification to require shifting zeroes, and
updates all currently merged SPI controller drivers to do so.

[PATCH] sched: fix cond_resched_softirq() offset

Remove the __resched_legal() check: it is conceptually broken.  The biggest
problem it had is that it can mask buggy cond_resched() calls.  A
cond_resched() call is only legal if we are not in an atomic context, with
two narrow exceptions:

 - if the system is booting
 - a reacquire_kernel_lock() down() done while PREEMPT_ACTIVE is set

But __resched_legal() hid this and just silently returned whenever
these primitives were called from invalid contexts. (Same goes for
cond_resched_locked() and cond_resched_softirq()).

Furthermore, the __legal_resched(0) call was buggy in that it caused
unnecessarily long softirq latencies via cond_resched_softirq().  (which is
only called from softirq-off sections, hence the code did nothing.)

The fix is to resurrect the efficiency of the might_sleep checks and to
only allow the narrow exceptions.

[PATCH] change WARN_ON back to "BUG: at ..."

WARN_ON() ever triggering is a kernel bug.  Do not try to paper over this
fact by suggesting to the user that this is 'only' a warning, as the
following recent commit does:

    [PATCH] Fix generic WARN_ON message

    A warning is a warning, not a BUG.

( it might make sense to rename BUG() to CRASH() and BUG_ON() to
  CRASH_ON(), but that does not change the fact that WARN_ON()
  signals a kernel bug. )

i and others objected to this change during lkml review:

  http://marc.theaimsgroup.com/?l=linux-kernel&m=116115160710533&w=2

still the change slipped upstream - grumble :)

Also, use the standard "BUG: " format to make it easier to grep logs and
to make it easier to google for kernel bugs.
