ef3d7714f6 Fix PNP build failure, bugzilla #11276
This fill fix the following regression list entry:

Bug-Entry	: http://bugzilla.kernel.org/show_bug.cgi?id=11276
Subject		: build error: CONFIG_OPTIMIZE_INLINING=y causes gcc 4.2 to do stupid things
Submitter	: Randy Dunlap <randy.dunlap@oracle.com>
Date		: 2008-08-06 17:18 (38 days old)

Handled-By	: Bjorn Helgaas <bjorn.helgaas@hp.com>
Patch		: http://lkml.org/lkml/2008/7/22/364

with what I believe is a better fix than the one referenced
in the regression entry above.

These PNP header interfaces try to work in such a way that
you can reference some of them even if PNP is not enabled,
and the compiler was expected to optimize everything away.

Which is mostly fine, except that there was one interface
for which there was not provided an inline "NOP" implementation.

Once we add that, all of these compile failures cannot handle
any more.

pnp: Provide NOP inline implementation of pnp_get_resource() when !PNP

Fixes kernel bugzilla #11276.

ba95487df9 crypto: talitos - Avoid consecutive packets going out with same IV
The SEC's h/w IV out implementation DMAs the trailing encrypted payload
block of the last encryption to ctx->iv.  Since the last encryption may
still be pending completion, we can sufficiently prevent successive
packets from being transmitted with the same IV by xoring with sequence
number.

Also initialize alg_list earlier to prevent oopsing on a failed probe.

8e82f8c34b memstick: fix MSProHG 8-bit interface mode support
- 8-bit interface mode never worked properly.  The only adapter I have
  which supports the 8b mode (the Jmicron) had some problems with its
  clock wiring and they discovered it only now.  We also discovered that
  ProHG media is more sensitive to the ordering of initialization
  commands.

- Make the driver fall back to highest supported mode instead of always
  falling back to serial.  The driver will attempt the switch to 8b mode
  for any new MSPro card, but not all of them support it.  Previously,
  these new cards ended up in serial mode, which is not the best idea
  (they work fine with 4b, after all).

- Edit some macros for better conformance to Sony documentation

8d99f83b94 rescan_partitions(): make device capacity errors non-fatal
Herton Krzesinski reports that the error-checking changes in
04ebd4aee5 ("block/ioctl.c and
fs/partition/check.c: check value returned by add_partition") cause his
buggy USB camera to no longer mount.  "The camera is an Olympus X-840.
The original issue comes from the camera itself: its format program
creates a partition with an off by one error".

Buggy devices happen.  It is better for the kernel to warn and to proceed
with the mount.

3aa04f1b07 atmel_lcdfb: disable LCD and DMA engines when suspending
When suspending the system with atmel_lcdfb enabled, I sometimes see
this:

	atmel_lcdfb atmel_lcdfb.0: FIFO underflow 0x10

Which can be explained by the fact that we're not stopping the LCD
controller and its DMA engine when suspending, we're just gating the
clocks to them.

There's another potential issue which may be harder to trigger but
much more nasty: If we gate the clocks at _just_ the right moment,
e.g. when the DMA engine is doing a bus transaction, we may cause the
DMA engine to violate the system bus protocol and cause a lockup.

Avoid these issues by shutting down the LCD controller before entering
suspend (and restarting it when resuming). This prevents the underrun
from happening in the first place, and prevents whatever nastiness is
happening when the bus clock stops in the middle of a DMA transfer.

8275d102f8 ia64: fix panic during `modprobe -r xpc'
If you are on ia64 and you modprobe xpc then modprobe -r xpc, you
immediately get a panic.  xpc depends on xp which depends on gru for a
symbol.  That symbol is only used when we are running on UV hardware.

Currently, the GRU driver detects we are not on UV hardware and does no
initializing.  It does not do the same check when unloading.  As a result,
the gru driver attempts to tear down stuff that was not setup.

This is a simple two-line workaround to get us through this release.  Once
2.6.28 is opened, we need to rework the symbols that xp is depending on
from gru so the gru driver can properly fail to load when hardware is not
available.
