Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
"These are mostly arm64 fixes with an additional arm(64) platform fix
for the initialisation of vexpress clocks (the latter only affecting
arm64; the arch/arm64 code is SoC agnostic and does not rely on early
SoC-specific calls)
- vexpress platform clocks initialisation moved earlier following the
arm64 move of of_clk_init() call in a previous commit
- Default DMA ops changed to non-coherent to preserve compatibility
with 32-bit ARM DT files. The "dma-coherent" property can be used
to explicitly mark a device coherent. The Applied Micro DT file
has been updated to avoid DMA cache maintenance for the X-Gene SATA
controller (the only arm64 related driver with such assumption in
-rc mainline)
- Fixmap correction for earlyprintk
- kern_addr_valid() fix for huge pages"
