y2038: convert more syscalls

Here is another set of system call changes to prepare the change over to
64-bit time_t. As before, the strategy is to change system calls that
take a 'struct timespec' argument over to 'struct __kernel_timespec',
which for now is defined to be the same but will get redefined to use a
64-bit time_t argument once we are ready to modify the system call tables.

The major change from previous patches is that the plan is no longer
to directly use the 'compat' system calls for providing compatibility
with the existing 32-bit time_t based entry points. Instead, we rename
the compat code to something that makes more sense on 32-bit architectures,
e.g. compat_timespec becomes old_timespec32.

With the renamed types in place, change over the 'stat' and 'utimes'
families of system calls, sched_rr_get_interval, recvmmsg and
rt_sigtimedwait. Another series for poll, select and io_pgetevents is
currently being tested.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:
"Since Martin is on vacation you get the s390 pull request from me:

- Host large page support for KVM guests. As the patches have large
impact on arch/s390/mm/ this series goes out via both the KVM and
the s390 tree.

- Add an option for no compression to the "Kernel compression mode"
menu, this will come in handy with the rework of the early boot
code.

- A large rework of the early boot code that will make life easier
for KASAN and KASLR. With the rework the bootable uncompressed
image is not generated anymore, only the bzImage is available. For
debuggung purposes the new "no compression" option is used.

- Re-enable the gcc plugins as the issue with the latent entropy
plugin is solved with the early boot code rework.

- More spectre relates changes:
+ Detect the etoken facility and remove expolines automatically.
+ Add expolines to a few more indirect branches.

- A rewrite of the common I/O layer trace points to make them
consumable by 'perf stat'.

- Add support for format-3 PCI function measurement blocks.

- Changes for the zcrypt driver:
+ Add attributes to indicate the load of cards and queues.
+ Restructure some code for the upcoming AP device support in KVM.

- Build flags improvements in various Makefiles.

- A few fixes for the kdump support.

- A couple of patches for gcc 8 compile warning cleanup.

- Cleanup s390 specific proc handlers.

- Add s390 support to the restartable sequence self tests.

- Some PTR_RET vs PTR_ERR_OR_ZERO cleanup.

- Lots of bug fixes"

s390/decompressor: reuse lib/mem.S for mem functions

Reusing arch/s390/lib/mem.S file solves a problem that sclp_early_core.c
and its dependencies have to be compiled with -march=z900 (no need to
compile compressed/misc.c with -march=z900). This also allows to avoid
mem functions duplicates, makes code a bit smaller and optimized mem
functions are utilized.
