7eeef2abe8 Merge branch 'core-debug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull wchan kernel address hiding from Ingo Molnar:
 "This fixes a wchan related information leak in /proc/PID/stat.

  There's a bit of an ABI twist to it: instead of setting the wchan
  field to 0 (which is our usual technique) we set it conditionally to a
  0/1 flag to keep ABI compatibility with older procps versions that
  only fetches /proc/PID/wchan (symbolic names) if the absolute wchan
  address is nonzero"

Pull irq updates from Thomas Gleixner:
 "The irq departement delivers:

   - Rework the irqdomain core infrastructure to accomodate ACPI based
     systems.  This is required to support ARM64 without creating
     artificial device tree nodes.

   - Sanitize the ACPI based ARM GIC initialization by making use of the
     new firmware independent irqdomain core

   - Further improvements to the generic MSI management

   - Generalize the irq migration on CPU hotplug

   - Improvements to the threaded interrupt infrastructure

   - Allow the migration of "chained" low level interrupt handlers

   - Allow optional force masking of interrupts in disable_irq[_nosysnc]

316dde2fe9 Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King:
 "In this ARM merge, we remove more lines than we add.  Changes include:

   - Enable imprecise aborts early, so that bus errors aren't masked
     until later in the boot.  This has the side effect that boot
     loaders which provoke these aborts can cause the kernel to crash
     early in boot, so we install a handler to report this event around
     the site where these are enabled.

   - Remove the buggy but impossible to enable cmpxchg syscall code.

   - Add unwinding annotations to some assembly code.

   - Add support for atomic half-word exchange for ARMv6k+.

   - Reduce ioremap() alignment for SMP/LPAE cases where we don't need
     the large alignment.

   - Addition of an "optimal" 3G configuration for systems with 1G of
     RAM.

   - Increase vmalloc space by 128M.

   - Constify some SMP operations structures, which have never been
     writable.

   - Improve ARMs dma_mmap() support for mapping DMA coherent mappings
     into userspace.

   - Fix to the NMI backtrace code in the IPI case on ARM where the
     failing CPU gets stuck for 10s waiting for its own IPI to be
     delivered.

   - Removal of legacy PM support from the AMBA bus driver.

   - Another fix for the previous fix of vdsomunge"

37b8e1ca0f irda: Delete an unnecessary check before the function call "irlmp_unregister_service"
The irlmp_unregister_service() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

b7ceb7d500 lightnvm: refactor phys addrs type to u64
For cases where CONFIG_LBDAF is not set. The struct ppa_addr exceeds its
type on 32 bit architectures. ppa_addr requires a 64bit integer to hold
the generic ppa format. We therefore refactor it to u64 and
replaces the sector_t usages with u64 for physical addresses.

353b39d1b1 ide: pdc202xx_new: Replace timeval with ktime_t
This driver uses 'struct timeval' which we are trying to remove since
32 bit time types will break in the year 2038 by replacing it with
ktime_t.

This patch changes do_gettimeofday() to ktime_get() because
ktime_get() returns a ktime_t while do_gettimeofday() returns struct
timeval.

This patch also uses ktime_us_delta() to get the elapsed time.

2404e607a9 blk-mq: avoid excessive boot delays with large lun counts
Hi,

Zhangqing Luo reported long boot times on a system with thousands of
LUNs when scsi-mq was enabled.  He narrowed the problem down to
blk_mq_add_queue_tag_set, where every queue is frozen in order to set
the BLK_MQ_F_TAG_SHARED flag.  Each added device will freeze all queues
added before it in sequence, which involves waiting for an RCU grace
period for each one.  We don't need to do this.  After the second queue
is added, only new queues need to be initialized with the shared tag.
We can do that by percolating the flag up to the blk_mq_tag_set, and
updating the newly added queue's hctxs if the flag is set.

This problem was introduced by commit 0d2602ca30 (blk-mq: improve
support for shared tags maps).

ccc0e7dc70 s390/dasd: fix disconnected device with valid path mask
Path verification is either done via dasd_eckd_read_conf() which is
triggered during online processing and resume or via
do_path_verification_work() which is triggered after path events.
The dasd_eckd_read_conf() version added paths unconditionally and did
not check if the path mask was empty. This led to devices having the
disconnected stop flag set but a valid path mask. So they where not
working although they had paths validated successfully. After a resume
this state could even not be solved with additional paths added.

Fix by checking for an empty path mask in dasd_eckd_read_conf() and
clearing the device stop bits for a newly added channel path.
