Subject: [PATCH 0/3] sparc32 SRMMU fixes for SMP

Hi folks,

Enabling SMP for sparc32 uncovered some issues in the SRMMU page-table
allocation code. One of these was introduced by me, but the other two
seem to have been there a while and are probably just exposed more
easily by my recent changes.

Tested on QEMU. I'm assuming these will go via David's tree.

Cheers,

Will

  sparc32: mm: Don't try to free page-table pages if ctor() fails
  sparc32: mm: Disable SPLIT_PTLOCK_CPUS
  sparc32: mm: Only call ctor()/dtor() functions for first and last user
