      powernv: Use _GLOBAL_TOC for opal wrappers · 19d36c21
      由 Jeremy Kerr 提交于 
      Currently, we can't call opal wrappers from modules when using the LE
ABIv2, which requires a TOC init. If we do we'll try and load the opal
entry point using the wrong toc and probably explode or worse jump to
the wrong address.

Nothing in upstream is making opal calls from a module, but we do export
one of the wrappers so we should fix this anyway.

This change uses the _GLOBAL_TOC() macro (rather than _GLOBAL) for the
opal wrappers, so that we can do non-local calls to them.

      powerpc/mm: Remove redundant #if case · ca5f1d16
      由 Aneesh Kumar K.V 提交于 
      Remove the check of CONFIG_PPC_SUBPAGE_PROT when deciding if
is_hugepage_only_range() is extern or inline. The extern version is in
slice.c and is built if CONFIG_PPC_MM_SLICES=y.

There was no build break possible because CONFIG_PPC_SUBPAGE_PROT is
only selectable under conditions which also mean CONFIG_PPC_MM_SLICES
will be selected.

      powerpc/mm: Fix build error with hugetlfs disabled · 6643773c
      由 Aneesh Kumar K.V 提交于 
      arch/powerpc/mm/slice.c:704:5: error: expected identifier or ‘(’ before numeric constant

     ^
make[1]: *** [arch/powerpc/mm/slice.o] Error 1
make: *** [arch/powerpc/mm/slice.o] Error 2

This got introduced via 1217d34b
"powerpc: Ensure global functions include their prototype". We
started including linux/hugetlb.h with that patch and now we have

 #define is_hugepage_only_range(mm, addr, len)	0

with hugetlbfs disabled.

      由 Linus Torvalds 提交于 
      Pull SCSI target updates from Nicholas Bellinger:
 "Here are the target updates for v3.18-rc2 code.  These where
  originally destined for -rc1, but due to the combination of travel
  last week for KVM Forum and my mistake of taking the three week merge
  window literally, the pull request slipped..  Apologies for that.

  Things where reasonably quiet this round.  The highlights include:

   - New userspace backend driver (target_core_user.ko) by Shaohua Li
     and Andy Grover
   - A number of cleanups in target, iscsi-taret and qla_target code
     from Joern Engel
   - Fix an OOPs related to queue full handling with CHECK_CONDITION
     status from Quinn Tran
   - Fix to disable TX completion interrupt coalescing in iser-target,
     that was causing problems on some hardware
   - Fix for PR APTPL metadata handling with demo-mode ACLs

  I'm most excited about the new backend driver that uses UIO + shared
  memory ring to dispatch I/O and control commands into user-space.
  This was probably the most requested feature by users over the last
  couple of years, and opens up a new area of development + porting of
  existing user-space storage applications to LIO.  Thanks to Shaohua +
  Andy for making this happen.

  Also another honorable mention, a new Xen PV SCSI driver was merged
  via the xen/tip.git tree recently, which puts us now at 10 target
  drivers in upstream! Thanks to David Vrabel + Juergen Gross for their
  work to get this code merged"
