Subject: [GIT PULL] s390 patches for the 3.16 merge window #1
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:
The biggest change in this patchset is conversion from the bootmem
bitmaps to the memblock code. This conversion requires two common
code patches to introduce the 'physmem' memblock list.
We experimented with ticket spinlocks but in the end decided against
them as they perform poorly on virtualized systems. But the spinlock
cleanup and some small improvements are included.
The uaccess code got another optimization, the get_user/put_user calls
are now inline again for kernel compiles targeted at z10 or newer
machines. This makes the text segment shorter and the code gets a
little bit faster.
And as always some bug fixes.
