Subject: [GIT PULL] arm64 updates (2nd set) for 4.6
Hi Linus,
Please pull the arm64 updates below, based on the arm64 for-next/core
branch I sent earlier during this merging window (on top of 4.5-rc4).
I'll be on holiday for two weeks but Will Deacon is going to take care
of the arm64 tree and any subsequent updates/fixes.
There is a minor conflict between the pr_notice() patch in this pull
request and commit dfd55ad85e4a ("arm64: vmemmap: use virtual projection
of linear region") in 4.5. The fix is already in -next but I include it
below FYI, basically s/vmmemap/VMEMMAP_START/ on top of these patches.
Thanks.
The following changes since commit 2776e0e8ef683a42fe3e9a5facf576b73579700e:

arm64: mm: allow preemption in copy_to_user_page (2016-03-24 16:32:54 +0000)
----------------------------------------------------------------
2nd set of arm64 updates for 4.6:
- KASLR bug fixes: use callee-saved register, boot-time I-cache
maintenance
- inv_entry asm macro fix (EL0 check typo)
- pr_notice("Virtual kernel memory layout...") splitting
- Clean-ups: use p?d_set_huge consistently, allow preemption around
copy_to_user_page, remove unused __local_flush_icache_all()
