0c44c2d0f4 x86: Use asm goto to implement better modify_and_test() functions
the various functions which do modify and test were unified and
optimized using "asm goto". However, this change missed the detail
that the bitops require an "Ir" constraint rather than an "er"
constraint ("I" = integer constant from 0-31, "e" = signed 32-bit
integer constant). This would cause code to miscompile if these
functions were used on constant bit positions 32-255 and the build to
fail if used on constant bit positions above 255.
Add the constraints as a parameter to the GEN_BINARY_RMWcc() macro to
avoid this problem.

shown below. Fix this warning by instead using sector_div() which is provided
by the kernel.h header file.

Andy Adamson reports:
The state manager is recovering expired state and recovery OPENs are being
processed. If kswapd is pruning inodes at the same time, a deadlock can occur
when kswapd calls evict_inode on an NFSv4.1 inode with a layout, and the
resultant layoutreturn gets an error that the state mangager is to handle,
causing the layoutreturn to wait on the (NFS client) cl_rpcwaitq.
At the same time an open is waiting for the inode deletion to complete in
__wait_on_freeing_inode.
If the open is either the open called by the state manager, or an open from
the same open owner that is holding the NFSv4 sequence id which causes the
OPEN from the state manager to wait for the sequence id on the Seqid_waitqueue,
then the state is deadlocked with kswapd.
The fix is simply to have layoutreturn ignore all errors except NFS4ERR_DELAY.
We already know that layouts are dropped on all server reboots, and that
it has to be coded to deal with the "forgetful client model" that doesn't
send layoutreturns.

Pull GPIO fixes from Linus Walleij:
"Here are a few more GPIO patches, we're a bit noisy for being the GPIO
subsystem, mostly due to the new descriptor API, but all is getting
into shape.
- Fix compile warnings
- Fix overly talkative diagnostic messages from usual use cases wrt
GPIO descriptors
- Add a documentation 00-INDEX
- Use platform GPIOs as fallback when ACPI or device tree is used as
the primary means to get GPIO lines
- A bug fix for the MPC8572/MPC8536 fixing erroneous input data"

Pull ARM SoC fixes from Olof Johansson:
"Another batch of fixes for ARM SoCs for 3.13. The diffstat is large,
mostly because of:
- Another set of fixes to fix regressions caused by moving OMAP from
board files to DT. Tony thinks this was the last major set of
fixes, with maybe just a few small patches to follow.
- More fixes for Marvell platforms, most dealing with misdescribed
PCIe hardware, i.e. incorrect number of busses on some SoCs, etc.
The line delta adds up due to various ranges moving around when
this is fixed.
But there's also:
- Some smaller tweaks to defconfigs to make more boards bootable in
my test setup for better coverage.
- There are also a few other smaller fixes, a short series for at91,
a couple of reverts for ux500, etc"

A smattering of fixes here, some core ones for the rate combination
issues for things other than simple bitmasks, for readback of byte
controls and for updating the power of value muxes plus a bunch of
driver fixes of varying severity.
The warning fix in the i.MX FIQ driver is fixing a warning introduced
by a previous fix.

If not, we could end up in the unfortunate situation where
we dereference a NULL pointer b/c we have cpuidle disabled.
This is the case when booting under Xen (which uses the
ACPI P/C states but disables the CPU idle driver) - and can
be easily reproduced when booting with cpuidle.off=1.
