Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"Not too much here, but we've addressed a couple of nasty issues in the
dma-mapping code as well as adding the halfword and byte variants of
load_acquire/store_release following on from the CSD locking bug that
you fixed in the core.
- fix perf devicetree warnings at probe time
- fix memory leak in __dma_free()
- ensure DMA buffers are always zeroed
- show IRQ trigger in /proc/interrupts (for parity with ARM)
- implement byte and halfword access for smp_{load_acquire,store_release}"
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: perf: Fix the pmu node name in warning message
arm64: perf: don't warn about missing interrupt-affinity property for PPIs
arm64: add missing PAGE_ALIGN() to __dma_free()
arm64: dma-mapping: always clear allocated buffers
ARM64: Enable CONFIG_GENERIC_IRQ_SHOW_LEVEL
arm64: add missing data types in smp_load_acquire/smp_store_release
