Pull arm64 fixes from Will Deacon:
 "The main thing here is to get us booting under qemu again after it
  turned out that not all of the PMU registers are emulated there,
  causing us to die early in boot.

   - Ensure we don't access PMU registers of the PMU is not implemented
     (fixes booting under QEMU)

   - Fix BUG_ON triggered during module loading with DEBUG_SET_MODULE_RONX

   - Ensure the kasan zero page is read-only

   - Hide __efistub_ symbol aliases from kallsyms, since they otherwise
     confuse the backtrace code

   - Ensure !PTE_WRITE kernel ptes are marked as read-only

   - defconfig updates based on requests and patches on the list

   - Other minor fixes (typos, build system)"
