Simplify syscallhdr.sh by letting grep sort out the ABIs that we want,
rather than relying on manual list matching.  This is safe since the
ABI strings already have to consist only of characters which are valid in C
macro names.

Generate system call tables and unistd_*.h automatically from the
tables in arch/x86/syscalls.  All other information, like NR_syscalls,
is auto-generated, some of which is in asm-offsets_*.c.

This allows us to keep all the system call information in one place,
and allows for kernel space and user space to see different
information; this is currently used for the ia32 system call numbers
when building the 64-bit kernel, but will be used by the x32 ABI in
the near future.

This also removes some gratuitious differences between i386, x86-64
and ia32; in particular, now all system call tables are generated with
the same mechanism.

Generated asm headers are supposed to live in
arch/*/include/generated/asm, but objhdr-y expect them to live in the
same directory they are generated in.  Instead of trying to cut that
particular Gordian knot, introduce genhdr-y that takes this into
account; the sole user of objhdr-y, linux/version.h, should be
migrated over at some later date.

Commit 8dc7a9c8 ("blackfin: Add export.h to files using

  virtio-pci: fix use after free

Commit 31a3ddda introduced
a use after free in virtio-pci. The main issue is
that the release method signals removal of the virtio device,
while remove signals removal of the pci device.

For example, on driver removal or hot-unplug,
virtio_pci_release_dev is called before virtio_pci_remove.
We then might get a crash as virtio_pci_remove tries to use the
device freed by virtio_pci_release_dev.

We allocate/free all resources together with the
pci device, so we can leave the release method empty.

  drm/radeon/kms/combios: fix dynamic allocation of PM clock modes

After commit e978aa7d ("cpuidle: Move dev->last_residency update to
driver enter routine; remove dev->last_state") setting acpi_idle_suspend
to 1 by acpi_processor_suspend() causes the ACPI cpuidle routines to
return error codes continuously, which in turn causes cpuidle to lock up
(hard).

However, acpi_idle_suspend doesn't appear to be useful for any
particular purpose (it's racy and doesn't really provide any real
protection), so it can be removed, which makes the problem go away.

Real world year equals the value in vrtc YEAR register plus an offset.
We used 1960 as the offset to make leap year consistent, but for a
device's first use, its YEAR register is 0 and the system year will
be parsed as 1960 which is not a valid UNIX time and will cause many
applications to fail mysteriously. So we use 1972 instead to fix this
issue.

Updated patch which adds a sanity check suggested by Mathias

This isn't a change in behaviour for systems, because 1972 is the one we
actually use. It's the old version in upstream which is out of sync with
