xtensa: introduce spill_registers_kernel macro

Most in-kernel users want registers spilled on the kernel stack and
don't require PS.EXCM to be set. That means that they don't need fixup
routine and could reuse regular window overflow mechanism for that,
which makes spill routine very simple.

xtensa: save current register frame in fast_syscall_spill_registers_fixup

We need it saved because it contains a3 where we track which register
windows we still need to spill, and fixup handler may call C exception
handlers. Also fix comments.

HID: usbhid: quirk for CY-TM75 75 inch Touch Overlay

There is timeout error during initialization:
kernel: [   11.733104] hid-multitouch 0003:1870:0110.0001: usb_submit_urb(ctrl) failed: -1
kernel: [   11.734093] hid-multitouch 0003:1870:0110.0001: timeout initializing reports

Adding quirk HID_QUIRK_NO_INIT_REPORTS can solve the problem.

HID: microsoft: Add ID's for Surface Type/Touch Cover 2

The Microsoft Surface Type/Touch cover 2 devices have the flag HID_DG_CONTACTID
in their reports.This causes the device to bind to the hid-multitouch driver,
which doesn't handle generic keyboard/mouse input events.  The patch adds
the hardware id's of the device to hid-microsoft and to the HID special
driver array, which makes the device get handled by hid-generic/hid-input
properly.

xtensa: fix fast_syscall_spill_registers

The original implementation could clobber registers under certain conditions.

The Xtensa processor architecture uses windowed registers and the original
implementation was using a4 as a temporary register, which under certain
conditions could be register a0 of the oldest window frame, and didn't always
restore the content correctly.

By moving the _spill_registers routine inside the fast system call, it frees
up one more register (the return address is not required anymore) for the
spill routine.

Without the patch the kernel generates the following error.

This patch helps to bypass this error and the device becomes

sata_sil: apply MOD15WRITE quirk to TOSHIBA MK2561GSYN

It's a bit odd to see a newer device showing mod15write; however, the
reported behavior is highly consistent and other factors which could
contribute seem to have been verified well enough.  Also, both
sata_sil itself and the drive are fairly outdated at this point making
the risk of this change fairly low.  It is possible, probably likely,
that other drive models in the same family have the same problem;
however, for now, let's just add the specific model which was tested.

arm, pm, vmpressure: add missing slab.h includes

arch/arm/mach-tegra/pm.c, kernel/power/console.c and mm/vmpressure.c
were somehow getting slab.h indirectly through cgroup.h which in turn
was getting it indirectly through xattr.h.  A scheduled cgroup change
drops xattr.h inclusion from cgroup.h and breaks compilation of these
three files.  Add explicit slab.h includes to the three files.

A pending cgroup patch depends on this change and it'd be great if
this can be routed through cgroup/for-3.14-fixes branch.

nfs: include xattr.h from fs/nfs/nfs3proc.c

fs/nfs/nfs3proc.c is making use of xattr but was getting linux/xattr.h
indirectly through linux/cgroup.h, which will soon drop the inclusion
of xattr.h.  Explicitly include linux/xattr.h from nfs3proc.c so that
compilation doesn't fail when linux/cgroup.h drops linux/xattr.h.

As the following cgroup changes will depend on these changes, it
probably would be easier to route this through cgroup branch.  Would
that be okay?
