Announce:
 --------------
 Dear RT folks!

 I'm pleased to announce the v3.10.14-rt9 patch set.

 Changes since v3.10.14-rt8

 - the threshold module option of hwlat is no longer ignored. Path sent
   by Mike Galbraith
 - two patches from Kirill Tkhai to get basic RT compiled on Sparc.
 - the ppc patch for the 5200 has been altered slightly. Patch sent by
   Wolfram Sang
 - A patch for SLAB to get it working on !RT (Thanks Corey Minyard).
 - a fix for "sleeping from invalid context" in clock_was_set_delayed().
   Patch by Yang Shi.
 - another fix for "sleeping from invalid context" in drain_all_stock.
   Patch also by Yang Shi.

 Known issues:

       - SLAB support not working

       - The cpsw network driver shows some issues.

       - bcache is disabled.

       - an ancient race (since we got sleeping spinlocks) where the
         TASK_TRACED state is temporary replaced while waiting on a rw
         lock and the task can't be traced.

 The delta patch against v3.10.10-rt6 is appended below and can be found
 here:
    https://www.kernel.org/pub/linux/kernel/projects/rt/3.10/incr/patch-3.10.14-rt8-rt9.patch.xz

 The RT patch against 3.10.14 can be found here:

    https://www.kernel.org/pub/linux/kernel/projects/rt/3.10/patch-3.10.14-rt9.patch.xz

 The split quilt queue is available at:

+Subject: [PATCH] Kind of revert "powerpc: 52xx: provide a default in
+ mpc52xx_irqhost_map()"
+
+This more or less reverts commit 6391f697d4892a6f233501beea553e13f7745a23.
+Instead of adding an unneeded 'default', mark the variable to prevent
+the false positive 'uninitialized var'. The other change (fixing the
+printout) needs revert, too. We want to know WHICH critical irq failed,
+not which level it had.

+
+The clock_was_set_delayed is called in hard IRQ handler (timer interrupt), which
+calls schedule_work.
+
+Under PREEMPT_RT_FULL, schedule_work calls spinlocks which could sleep, so it's
+not safe to call schedule_work in interrupt context.
+
+Reference upstream commit b68d61c705ef02384c0538b8d9374545097899ca
+(rt,ntp: Move call to schedule_delayed_work() to helper thread)
+from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git, which
+makes a similar change.
+
+add a helper thread which does the call to schedule_work and wake up that
+thread instead of calling schedule_work directly.

+Subject: [PATCH] net: iwlwifi: request only a threaded handler for
+ interrupts
+
+On RT the trans_pcie->irq_lock lock is converted into a sleeping lock
+and can't be used in primary irq handler. The lock is used in mutliple
+places which means turning it into a raw lock could increase the
+latency of the system.
+For now both handlers are moved into the thread.

+Subject: [PATCH] sparc: provide EARLY_PRINTK for SPARC
+
+sparc does not have CONFIG_EARLY_PRINTK option.
+
+So early-printk-consolidate.patch breaks compilation:
+
+arch/sparc/built-in.o: In function `setup_arch':
+(.init.text+0x15e4): undefined reference to `early_console'
+arch/sparc/built-in.o: In function `setup_arch':
+(.init.text+0x15ec): undefined reference to `early_console'
+
+The below addition fixes that.

+Subject: [PATCH] sparc64: Remove RWSEM export leftovers
+
+The functions
+
+			__down_read
+			__down_read_trylock
+			__down_write
+			__down_write_trylock
+			__up_read
+			__up_write
+			__downgrade_write
+
+are implemented inline, so remove corresponding EXPORT_SYMBOLs
+(They lead to compile errors on RT kernel).
