e390f9a968 objtool, modules: Discard objtool annotation sections for modules
The '__unreachable' and '__func_stack_frame_non_standard' sections are
only used at compile time.  They're discarded for vmlinux but they
should also be discarded for modules.

Since this is a recurring pattern, prefix the section names with
".discard.".  It's a nice convention and vmlinux.lds.h already discards
such sections.

Also remove the 'a' (allocatable) flag from the __unreachable section
since it doesn't make sense for a discarded section.

522b837c67 checkpatch: warn when formats use %Z and suggest %z
vsnprintf extension %Z<foo> is non-standard C.  Suggest the use of %z
instead.

Miscellanea:

 - Correct the misuse of type string PRINTF_0xDECIMAL type strings are
   supposed to be uppercase only. Fix this and add tr/[a-z]/[A-Z] to the
   type check in case I forget this again sometime in the future.

 - Improve the mechanism to find these defects so all 3 current checks
   are done on the format string

d7f6724366 scripts/spelling.txt: add some typo-words
I wrote a simple script to find new typo not in spelling.txt.
(https://github.com/jinb-park/find-linux-kernel-typo)

and get following result:

	[ rank ]
	63 paramaters
	18 alignement
	9 strucuture
	....

The number means how many files include the typo.
This patch adds these common typo.

"userland" etc., so must draw a line somewhere.

Pull OpenRISC updates from Stafford Horne:
 "Highlights include:

   - optimized memset and memcpy routines, ~20% boot time saving

   - support for cpu idling

   - adding support for l.swa and l.lwa atomic operations (in spec from
     2014)

   - use atomics to implement: bitops, cmpxchg, futex

   - the atomics are in preparation for SMP support"

9533047363 checkpatch: remove false unbalanced braces warning
Lines containing "} else {" should not be detected as unbalanced braces.
But the second check can be reduced to ".+else\s*{" and it therefore
never checked if the beginning of a line contains any other character
(like the relevant "}").  This check would also return true for "} else
{" and create warnings like

    CHECK: Unbalanced braces around else statement
    #391: FILE: ./net/batman-adv/tvlv.c:391:
    +   } else {

The check can be changed to check the whole line for the missing "}" to
avoid this false positive.

38705613b7 powerpc updates for 4.11 part 1.
Highlights include:
 
  - Support for direct mapped LPC on POWER9, giving Linux direct access to
    devices that may be on there such as a UART.
 
  - Memory hotplug support for the Power9 Radix MMU.
 
  - Add new AUX vectors describing the processor's cache geometry, to be used by
    glibc.
 
  - The ability for a guest to ask the hypervisor to resize the guest's hash
    table, and in addition support for doing so automatically when memory is
    hotplugged into/out-of the guest. This allows the hash table to be sized
    based on the current memory usage of the guest, rather than the maximum
    possible memory usage.
 
  - Implementation of optprobes (kprobe optimisation) for powerpc.
 
 In addition there's the topic branch shared with the KVM tree, which includes
 support for guests to use the Radix MMU on Power9.

Merge tag 'powerpc-4.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc updates from Michael Ellerman:
 "Highlights include:

   - Support for direct mapped LPC on POWER9, giving Linux direct access
     to devices that may be on there such as a UART.

   - Memory hotplug support for the Power9 Radix MMU.

   - Add new AUX vectors describing the processor's cache geometry, to
     be used by glibc.

   - The ability for a guest to ask the hypervisor to resize the guest's
     hash table, and in addition support for doing so automatically when
     memory is hotplugged into/out-of the guest. This allows the hash
     table to be sized based on the current memory usage of the guest,
     rather than the maximum possible memory usage.

   - Implementation of optprobes (kprobe optimisation) for powerpc.

  In addition there's the topic branch shared with the KVM tree, which
  includes support for guests to use the Radix MMU on Power9.
