arm64: add support for ioremap() block mappings

2016-02-18T18:16:16+00:00

This wires up the existing generic huge-vmap feature, which allows
ioremap() to use PMD or PUD sized block mappings. It also adds support
to the unmap path for dealing with block mappings, which will allow us
to unmap the __init region using unmap_kernel_range() in a subsequent
patch.

mm, thp: remove infrastructure for handling splitting PMDs

2016-01-16T01:56:32+00:00

With new refcounting we don't need to mark PMDs splitting.  Let's drop
code to handle this.

Merge tag 'metag-for-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/metag

2015-09-09T17:27:59+00:00

Pull metag updates from James Hogan:
 "Metag architecture changes for v4.3.

  Just a couple of changes for v4.3-rc1.  A preparatory IRQ patch to
  prepare for moving irq_data struct members, and a tweak to
  Documentation/features since Meta2 could support THP"

* tag 'metag-for-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/metag:
  Documentation/features/vm: Meta2 is capable of THP
  metag/irq: Use access helper irq_data_get_affinity_mask()

Documentation/features/vm: Meta2 is capable of THP

2015-09-07T07:57:53+00:00

Change metag Transparent Huge Pages (THP) support from .. to TODO. Meta2
has variable sized pages, between 4KB and 4MB, specified at the 1st
level page table level, and already supports hugetlbfs, so supporting
THP is theoretically possible too.
