Merge tag 'asm-generic' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic updates from Arnd Bergmann:
"This has three changes for asm-generic that did not really fit into
any other branch as normal asm-generic changes do. One is a fix for a
build warning, the other two are more interesting:
* A patch from Mark Brown to allow using the common clock
infrastructure on all architectures, so we can use the clock API in
architecture independent device drivers.
* The UAPI split patches from David Howells for the asm-generic
files. There are other architecture specific series that are going
through the arch maintainer tree and that depend on this one.
There may be a few small merge conflicts between Mark's patch and the
following arch header file split patches. In each case the solution
will be to keep the new "generic-y += clkdev.h" line, even if it ends
up being the only line in the Kbuild file."
* tag 'asm-generic' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:
UAPI: (Scripted) Disintegrate include/asm-generic
asm-generic: Add default clkdev.h
asm-generic: xor: mark static functions as __maybe_unused
