+Subject: alarmtimer: return EINVAL instead of ENOTSUPP if rtcdev doesn't exist
+
+From: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com>
+
+commit 98d6f4dd84a134d942827584a3c5f67ffd8ec35f upstream.
+
+Fedora Ruby maintainer reported latest Ruby doesn't work on Fedora Rawhide
+on ARM. (http://bugs.ruby-lang.org/issues/9008)
+
+Because of, commit 1c6b39ad3f (alarmtimers: Return -ENOTSUPP if no
+RTC device is present) intruduced to return ENOTSUPP when
+clock_get{time,res} can't find a RTC device. However this is incorrect.
+
+First, ENOTSUPP isn't exported to userland (ENOTSUP or EOPNOTSUP are the
+closest userland equivlents).
+
+Second, Posix and Linux man pages agree that clock_gettime and
+clock_getres should return EINVAL if clk_id argument is invalid.
+While the arugment that the clockid is valid, but just not supported
+on this hardware could be made, this is just a technicality that
+doesn't help userspace applicaitons, and only complicates error
+handling.
+
+Thus, this patch changes the code to use EINVAL.

+Subject: devpts: plug the memory leak in kill_sb
+
+From: Ilija Hadzic <ihadzic@research.bell-labs.com>
+
+commit 66da0e1f9034140ae2f571ef96e254a25083906c upstream.
+
+When devpts is unmounted, there may be a no-longer-used IDR tree hanging
+off the superblock we are about to kill. This needs to be cleaned up
+before destroying the SB.
+
+The leak is usually not a big deal because unmounting devpts is typically
+done when shutting down the whole machine. However, shutting down an LXC
+container instead of a physical machine exposes the problem (the garbage
+is detectable with kmemleak).

+Subject: genirq: Set the irq thread policy without checking CAP_SYS_NICE
+
+From: Thomas Pfaff <tpfaff@pcs.com>
+
+commit bbfe65c219c638e19f1da5adab1005b2d68ca810 upstream.
+
+In commit ee23871389 ("genirq: Set irq thread to RT priority on
+creation") we moved the assigment of the thread's priority from the
+thread's function into __setup_irq(). That function may run in user
+context for instance if the user opens an UART node and then driver
+calls requests in the ->open() callback. That user may not have
+CAP_SYS_NICE and so the irq thread won't run with the SCHED_OTHER
+policy.
+
+This patch uses sched_setscheduler_nocheck() so we omit the CAP_SYS_NICE
+check which is otherwise required for the SCHED_OTHER policy.

+Subject: perf tools: Remove cast of non-variadic function to variadic
+
+From: Michael Hudson-Doyle <michael.hudson@linaro.org>
+
+commit 53805eca3d89b095062c11a6798689bb0af09216 upstream.
+
+The 4fb71074a570 (perf ui/hist: Consolidate hpp helpers) cset introduced
+a cast of percent_color_snprintf to a function pointer type with
+varargs. Change percent_color_snprintf to be variadic and remove the
+cast.
+
+The symptom of this was all percentages being reported as 0.00% in perf
+report --stdio output on the armhf arch.

+Subject: perf tools: Synthesize anon MMAP records again
+
+From: Don Zickus <dzickus@redhat.com>
+
+commit 9d4ecc8893832337daf241236841db966fa53489 upstream.
+
+When introducing the PERF_RECORD_MMAP2 in:
+
+5c5e854bc760 perf tools: Add attr->mmap2 support
+
+A check for the number of entries parsed by sscanf was introduced that
+assumed all of the 8 fields needed to be correctly parsed so that
+particular /proc/pid/maps line would be considered synthesizable.
+
+That broke anon records synthesizing, as it doesn't have the 'execname'
+field.
+
+Fix it by keeping the sscanf return check, changing it to not require
+that the 'execname' variable be parsed, so that the preexisting logic
+can kick in and set it to '//anon'.
+
+This should get things like JIT profiling working again.

+Subject: rbtree: fix rbtree_postorder_for_each_entry_safe() iterator
+
+From: Jan Kara <jack@suse.cz>
+
+commit 1310a5a99d900ee30b9f171146406bde0c6c2bd4 upstream.
+
+The iterator rbtree_postorder_for_each_entry_safe() relies on pointer
+underflow behavior when testing for loop termination. In particular it
+expects that
+
+ &rb_entry(NULL, type, field)->field
+
+is NULL. But the result of this expression is not defined by a C standard
+and some gcc versions (e.g. 4.3.4) assume the above expression can never
+be equal to NULL. The net result is an oops because the iteration is not
+properly terminated.
+
+Fix the problem by modifying the iterator to avoid pointer underflows.
