It's a lot smaller than last week, with the star of the show being a couple of fixes to head.S addressing a boot regression introduced by the recent overhaul of that code in non-default configurations (i.e. KASLR disabled). The first of those two resolves the issue reported (and bisected) by Mikulus in the wait_on_bit() thread. Cheers, Will --->8 The following changes since commit 714f3cbd70a4db9f9b7fe5b8a032896ed33fb824: arm64/sme: Don't flush SVE register state when handling SME traps (2022-08-23 11:29:12 +0100) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git tags/arm64-fixes for you to fetch changes up to 5fbc49cef91916140a305f22f7430e9a7ea0c6b4: arm64: mm: Reserve enough pages for the initial ID map (2022-09-01 12:02:39 +0100) ---------------------------------------------------------------- arm64 fixes for -rc4 - Fix two boot issues caused by the recent head.S rework when !KASLR - Fix calculation of crashkernel memory reservation - Fix bogus error check in PMU IRQ probing code ---------------------------------------------------------------- Ard Biesheuvel (2): arm64: head: Ignore bogus KASLR displacement on non-relocatable kernels arm64: mm: Reserve enough pages for the initial ID map Levi Yun (1): arm64/kexec: Fix missing extra range for crashkres_low.
