Subject: [GIT PULL] s390 patches for the 4.4 merge window
Hi Linus,
please pull from the 'for-linus' branch of
git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git for-linus
to receive the following updates:
There is only one new feature in this pull for the 4.4 merge window,
most of it is small enhancements, cleanup and bug fixes.
* Add the s390 backend for the software dirty bit tracking. This adds two
new pgtable functions pte_clear_soft_dirty and pmd_clear_soft_dirty which
is why there is a hit to arch/x86/include/asm/pgtable.h in this pull
request.
* A series of cleanup patches for the AP bus, this includes the removal of
the support for two outdated crypto cards (PCICC and PCICA).
* The irq handling / signaling on buffer full in the runtime instrumentation
code is dropped.
* Some micro optimizations: remove unnecessary memory barriers for a couple
of functions: [smb_]rmb, [smb_]wmb, atomics, bitops, and for spin_unlock.
Use the builtin bswap if available and make test_and_set_bit_lock more
cache friendly.
* Statistics and a tracepoint for the diagnose calls to the hypervisor.
* The CPU measurement facility support to sample KVM guests is improved.
* The vector instructions are now always enabled for user space processes
if the hardware has the vector facility. This simplifies the FPU handling
code. The fpu-internal.h header is split into fpu internals, api and types
just like x86.
* Cleanup and improvements for the common I/O layer.
* Rework udelay to solve a problem with kprobe. udelay has busy loop
semantics but still uses an idle processor state for the wait.
