Hi Linus,

Please pull the following arm64 fixes for -rc1. Usual summary in the
tag, but we've got a couple of build fixes when using LLD, a missing TLB
invalidation and a workaround for broken firmware on SoCs with CPUs that
implement MPAM.

Cheers,

Will

  arm64: Add override for MPAM (2025-06-02 13:49:09 +0100)

----------------------------------------------------------------
arm64 fixes for -rc1

- Disable problematic linker assertions for broken versions of LLD.

- Work around sporadic link failure with LLD and various randconfig
  builds.

- Fix missing invalidation in the TLB batching code when reclaim races
  with mprotect() and friends.

- Add a command-line override for MPAM to allow booting on systems with
  broken firmware.
