Merge tag 'powerpc-6.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc updates from Michael Ellerman:

 - Remove our now never-true definitions for pgd_huge() and p4d_leaf().

 - Add pte_needs_flush() and huge_pmd_needs_flush() for 64-bit.

 - Add support for syscall wrappers.

 - Add support for KFENCE on 64-bit.

 - Update 64-bit HV KVM to use the new guest state entry/exit accounting
   API.

 - Support execute-only memory when using the Radix MMU (P9 or later).

 - Implement CONFIG_PARAVIRT_TIME_ACCOUNTING for pseries guests.

 - Updates to our linker script to move more data into read-only
   sections.

 - Allow the VDSO to be randomised on 32-bit.

 - Many other small features and fixes.
