[GIT PULL] arm64 fixes for -rc1

[Will Deacon]

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.

[GIT PULL] arm64 fixes for -rc1

[Will Deacon]

Hi Linus,

Please pull these arm64 fixes for -rc1 that address issues either found
or introduced during this merge window. The only one that isn't strictly
a fix is the kpti cleanup, as I ended up queuing it late due to some
inter-branch dependencies and wanted to give it some more time in -next.

Summary in the tag.

Cheers,

Will

[GIT PULL] arm64 fixes for -rc1

[Will Deacon]

Hi Linus,

Please can you pull these two arm64 fixes for -rc1?

One fixes a warning that started showing up with GCC 16 and the other
fixes a lockup in udelay() when running with a vCPU loaded on a CPU with
the new-fangled WFIT instruction.

Cheers,

Will
