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