arm64: defconfig updates
v2 cover arm64: defconfig updates
This patch series was based on 4.6-rc4.
Shawn/Sascha, in the discussion here:
http://permalink.gmane.org/gmane.linux.ports.arm.kernel/494010
...Arnd and Will suggest having this series go in through the SoC maintainers if possible.
As far as I know, when doing a 'make defconfig' immediately followed by 'make savedefconfig', the resulting defconfig should exactly match the original defconfig. This was not the case for arm64 and patch 1 cleans that up.
Patch 2 enables 48-bit VA to allow certain armv8 SoCs to cover all of their physical memory regions. (see email thread:
http://www.spinics.net/lists/arm-kernel/msg497210.html)
Patch 3 enables some additional device for Freescale/NXP SoCs.

Applied these two.

arm64: defconfig: enable freescale/nxp config options
But this one doesn't apply to v4.6-rc1.

Yes. There is a patch from Will that went into rc2 that was a major defconfig update:
431597b arm64: defconfig: updates for 4.6
...so basing my patch on rc1 would have caused it not to apply to later kernels.
The only sane thing I could think of to do was base my patches against the latest rc, which was 4.6-rc4, which I mentioned in the cover letter.
I can rebase that patch if needed, but it will most likely produce a merge conflict later. The defconfig file really should not be hand edited, because that will quite likely cause it to get out of sync with what 'make savedefconfig' produces...so I'm trying to avoid someone having to manually fix a merge conflict.
Thanks,
Stuart

Okay, I rebased my defconfig64 branch onto v4.6-rc2 and applied all 3 patches.
