One of them is just a trivial documentation fix, whereas the other two address a warning in the kexec code and a crash in ftrace on systems implementing BTI. The latter patch has a couple of ugly ifdefs which Mark plans to clean up separately, but as-is the patch is straightforward for backporting to stable kernels. Cheers, Will --->8 The following changes since commit 94902d849e85093aafcdbea2be8e2beff47233e6: arm64: uaccess: avoid blocking within critical sections (2021-11-24 09:16:26 +0000) 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 35b6b28e69985eafb20b3b2c7bd6eca452b56b53: arm64: ftrace: add missing BTIs (2021-12-02 10:18:32 +0000) ---------------------------------------------------------------- arm64 fixes for -rc4 - Add missing BTI landing instructions to the ftrace*_caller trampolines - Fix kexec() WARN when DEBUG_VIRTUAL is enabled - Fix PAC documentation by removing stale references to compiler flags ---------------------------------------------------------------- Kuan-Ying Lee (1): arm64: update PAC description for kernel Mark Rutland (2): arm64: kexec: use __pa_symbol(empty_zero_page) arm64: ftrace: add missing BTIs Documentation/arm64/pointer-authentication.rst | 9 ++++----- arch/arm64/kernel/entry-ftrace.S | 6 ++++++ arch/arm64/kernel/machine_kexec.c | 2 +- 3 files changed, 11 insertions(+), 6 deletions(-)
