For whatever reason GCC isn't able to figure things out in
the control flow (in particular when min() and max() expressions
are involved) on sparc as well as it can on x86.
So lots of useless incorrect user copy warnings get spewed and the
full-on compile failure mode of the user copy checks were never usable
on sparc at all.
People can debug these kinds of problems on x86.

After b0f82b81fe ("perf: Drop the skip
argument from perf_arch_fetch_regs_caller") the build broke on sparc64
due to the lack of a module symbol export of __perf_arch_fetch_caller_regs.
But that assembler helper can actually be complete eliminated now that
the semantics of this interface have been greatly simplified.

Based on patches from Sonny Rao and Milton Miller...
Combined the patches to fix up clean_tx_irq and clean_rx_irq.
The PowerPC architecture does not require loads to independent bytes
to be ordered without adding an explicit barrier.
In ixgbe_clean_rx_irq we load the status bit then load the packet data.
With packet split disabled if these loads go out of order we get a
stale packet, but we will notice the bad sequence numbers and drop it.
The problem occurs with packet split enabled where the TCP/IP header
and data are in different descriptors. If the reads go out of order
we may have data that doesn't match the TCP/IP header. Since we use
hardware checksumming this bad data is never verified and it makes it
all the way to the application.
This bug was found during stress testing and adding this barrier has
been shown to fix it. The bug can manifest as a data integrity issue
(bad payload data) or as a BUG in skb_pull().
This was a nasty bug to hunt down, if people agree with the fix I think
it's a candidate for stable.
Previously Submitted to e1000-devel only for ixgbe
http://marc.info/?l=e1000-devel&m=126593062701537&w=3
We've now seen this problem hit with other device drivers (e1000e mostly)
So I'm resubmitting with fixes for other Intel Device Drivers with
similar issues.

Building ixgbe without DCB_CONFIG and FCOE_CONFIG will cause
a build error. This resolves the build error by wrapping
the fcoe.up in CONFIG_IXGBE_DCB ifdefs.
Also frames were being priority VLAN tagged even without DCB
enabled. This fixes this so that 8021Q priority tags are
only added with DCB actually enabled.

All callers expect a boolean result which is true if the region
overlaps a reserved region. However, the implementation actually
returns -1 if there is no overlap, and a region index (0 based)
if there is.
Make it behave as callers (and common sense) expect.

This patch uses an RCU-inspired approach to fix it. In the RX tasklet's
find_vcc() function we first refuse to use a VCC which already has the
ATM_VF_READY bit cleared. And in the VCC close function, we synchronise
with the tasklet to ensure that it can't still be using the VCC before
we continue and allow the VCC to be destroyed.

Although netif_rx() isn't expected to be called in process context with

rcu_read_lock() won't disable preemption, so preempt_disable() should be
called explictly.

Fixed up conflicts in fs/cifs/* as per Tejun. Other trivial conflicts in
include/linux/workqueue.h, kernel/trace/Kconfig and kernel/workqueue.c
Commit f9d7562fdb "nfsd4: share file
descriptors between stateid's" didn't correctly account for O_RDWR opens.
Symptoms include leaked files, resulting in failures to unmount and/or
warnings about orphaned inodes on reboot.

Call the gpio reset platform function instead of using the flawed
ac97 functionality of the MPC5200(b)
From MPC5200B User's Manual:
"Some AC97 devices goes to a test mode, if the Sync line is high
during the Res line is low (reset phase). To avoid this behavior the
Sync line must be also forced to zero during the reset phase. To do
that, the pin muxing should switch to GPIO mode and the GPIO control
register should be used to control the output lines."

Work around a silicon bug in the ac97 reset functionality of the
mpc5200(b). The implementation of the ac97 "cold" reset is flawed.
If the sync and output lines are high when reset is asserted the
attached ac97 device may go into test mode. Avoid this by
reconfiguring the psc to gpio mode and generating the reset manually.
