If the kernel is compiled with function tracer support the -pg compile option
is passed to gcc to generate extra code into the prologue of each function.
This patch replaces the "open-coded" -pg compile flag with a CC_FLAGS_FTRACE
makefile variable which architectures can override if a different option
should be used for code generation.

Christian Borntraeger reported that the now missing diag 44 calls (voluntary
time slice end) does cause a performance regression for stop_machine() calls
if a machine has more virtual cpus than the host has physical cpus.
This patch mainly reverts 57f2ffe14fd125c2 ("s390: remove diag 44 calls from
cpu_relax()") with the exception that we still do not issue diag 44 calls if
running with smt enabled. Due to group scheduling algorithms when running in
LPAR this would lead to significant latencies.
However, when running in LPAR we do not have more virtual than physical cpus.

Upcoming versions of secure key management facilities (CCA and
EP11) require information about the maximum number of supported
ap domains in order to service TKE requests properly. With IBM
z13 the number of available domains (so far 16) has increased up
to 85. This number varies depending on machine types and models.
Therefore the new sysfs attribute 'ap_max_domain_id' provides
this limit of supported ap domains. Upcoming releases for CCA
and EP11 will use this new information. Without this problem fix
it is not possible to retrieve reliable information about the
maximum number of supported ap domains. Thus, customers are not
able to perform key management for CCA and EP11 coprocessor
adapters.

Add the compare-and-delay instruction to the spin-lock and rw-lock
retry loops. A CPU executing the compare-and-delay instruction stops
until the lock value has changed. This is done to make the locking
code for contended locks to behave better in regard to the multi-
hreading facility. A thread of a core executing a compare-and-delay
will allow the other threads of a core to get a larger share of the
core resources.

Introduce a wildcard character to filter a range of z/VM user IDs with a single

Commit 725908110a1f ("s390: add SMT support") added a check for
CONFIG_ZFCPDUMP. But the Kconfig symbol ZFCPDUMP was removed in v3.16
through commit bf28a5970de3 ("s390/dump: Remove CONFIG_ZFCPDUMP"). So
this check will always evaluate to false. No one noticed probably
because the code also checks for CONFIG_CRASH_DUMP which "also enables
s390 zfcpdump".
Dump the unneeded check.

The multi-threading facility is introduced with the z13 processor family.
This patch adds code to detect the multi-threading facility. With the
facility enabled each core will surface multiple hardware threads to the
system. Each hardware threads looks like a normal CPU to the operating
system with all its registers and properties.
The SCLP interface reports the SMT topology indirectly via the maximum
thread id. Each reported CPU in the result of a read-scp-information
is a core representing a number of hardware threads.
To reflect the reduced CPU capacity if two hardware threads run on a
single core the MT utilization counter set is used to normalize the
raw cputime obtained by the CPU timer deltas. This scaled cputime is
reported via the taskstats interface. The normal /proc/stat numbers
are based on the raw cputime and are not affected by the normalization.

For C language, it treats array parameter as a pointer, so sizeof for an
array parameter is equal to sizeof for a pointer, which causes compiler
warning (with allmodconfig by gcc 5):
./arch/s390/include/asm/timex.h: In function 'get_tod_clock_ext':
./arch/s390/include/asm/timex.h:76:32: warning: 'sizeof' on array function parameter 'clk' will return size of 'char *' [-Wsizeof-array-argument]
typedef struct { char _[sizeof(clk)]; } addrtype;
^
Can use macro CLOCK_STORE_SIZE instead of all related hard code numbers,
which also can avoid this warning. And also add a tab to CLOCK_TICK_RATE
definition to match coding styles.
[heiko.carstens@de.ibm.com]:
Chen's patch actually fixes a bug within the get_tod_clock_ext() inline assembly
where we incorrectly tell the compiler that only 8 bytes of memory get changed
instead of 16 bytes.
This would allow gcc to generate incorrect code. Right now this doesn't seem to
be the case.
Also slightly changed the patch a bit.
- renamed CLOCK_STORE_SIZE to STORE_CLOCK_EXT_SIZE
- changed get_tod_clock_ext() to receive a char pointer parameter

in the cpu time accounting function vtime_account_irq_enter

This is redundant as the function virt_timer_forward is always

Kernel oops caused by invalid parameter at TAPQ instruction:
On older systems where the QCI instruction is not available
all possible domains are probed via TAPQ instruction. The
range for the probe has been extended with the > 16 domain
support now leading to a possible specification exception
when this instruction is called for probing higher values
within the new range. This may happen during insmod and/or
ap bus reset only on machines without a QCI instruction (z10,
z196, z114), zEC12 and newer systems are not affected.
The fix modifies the domain checking function to limit the
allowed range if no QCI info is available.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace related fixes from Eric Biederman:
"As these are bug fixes almost all of thes changes are marked for
backporting to stable.
The first change (implicitly adding MNT_NODEV on remount) addresses a
regression that was created when security issues with unprivileged
remount were closed. I go on to update the remount test to make it
easy to detect if this issue reoccurs.
Then there are a handful of mount and umount related fixes.
Then half of the changes deal with the a recently discovered design
bug in the permission checks of gid_map. Unix since the beginning has
allowed setting group permissions on files to less than the user and
other permissions (aka ---rwx---rwx). As the unix permission checks
stop as soon as a group matches, and setgroups allows setting groups
that can not later be dropped, results in a situtation where it is
possible to legitimately use a group to assign fewer privileges to a
process. Which means dropping a group can increase a processes
privileges.
The fix I have adopted is that gid_map is now no longer writable
without privilege unless the new file /proc/self/setgroups has been
set to permanently disable setgroups.
The bulk of user namespace using applications even the applications
using applications using user namespaces without privilege remain
unaffected by this change. Unfortunately this ix breaks a couple user
space applications, that were relying on the problematic behavior (one
of which was tools/selftests/mount/unprivileged-remount-test.c).
To hopefully prevent needing a regression fix on top of my security
fix I rounded folks who work with the container implementations mostly
like to be affected and encouraged them to test the changes.

Dave Hansen reports that commit fb7332a9fedf ("mmu_gather: move minimal
range calculations into generic code") caused a performance problem:
"tlb_finish_mmu() goes up about 9x in the profiles (~0.4%->3.6%) and
tlb_flush_mmu_free() takes about 3.1% of CPU time with the patch
applied, but does not show up at all on the commit before"
and the reason is that Will moved the test for whether we need to flush
from tlb_flush_mmu() into tlb_flush_mmu_tlbonly(). But that meant that
tlb_flush_mmu_free() basically lost that check.
Move it back into tlb_flush_mmu() where it belongs, so that it covers
both tlb_flush_mmu_tlbonly() _and_ tlb_flush_mmu_free().

git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input subsystem updates from Dmitry Torokhov:
"Two new drivers for Elan hardware (for I2C touchpad and touchscreen
found in several Chromebooks and other devices), a driver for Goodix
touch panel, and small fixes to Cypress I2C trackpad and other input
drivers.
Also we switched to use __maybe_unused instead of gating suspend/
resume code with #ifdef guards to get better compile coverage"

git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse
Pull fuse update from Miklos Szeredi:
"The first part makes sure we don't hold up umount with pending async
requests. In addition to being a cleanup, this is a small behavioral
change (for the better) and unlikely to break anything.
The second part prepares for a cleanup of the fuse device I/O code by
adding a helper for simple request submission, with some savings in
line numbers already realized"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse:
fuse: use file_inode() in fuse_file_fallocate()
fuse: introduce fuse_simple_request() helper
fuse: reduce max out args
fuse: hold inode instead of path after release
fuse: flush requests on umount
fuse: don't wake up reserved req in fuse_conn_kill()

make sure 'value' is not null. otherwise __ceph_setxattr will remove
the extended attribute.
