Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- SPsel register initialisation on reset as the architecture defines
its state as unknown
- Use READ_ONCE when dereferencing pmd_t pointers to avoid race
conditions in page_vma_mapped_walk() (or fast GUP) with concurrent
modifications of the page table
- Avoid invoking the mm fault handling code for kernel addresses (check
against TASK_SIZE) which would otherwise result in calling
might_sleep() in atomic context
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: fault: Route pte translation faults via do_translation_fault
arm64: mm: Use READ_ONCE when dereferencing pointer to pte table
arm64: Make sure SPsel is always set
