I'm announcing the release of the 6.12.43 kernel. All users of the 6.12 kernel series must upgrade. The updated 6.12.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.12.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Documentation/filesystems/fscrypt.rst | 37 +-- Documentation/firmware-guide/acpi/i2c-muxes.rst | 8 Makefile | 2 arch/arm/mach-rockchip/platsmp.c | 15 -

[PATCH] x86: XOP prefix instructions decoder support

by Masami Hiramatsu (Google)

From: Masami Hiramatsu (Google) <mhiramat(a)kernel.org> Support decoding AMD's XOP prefix encoded instructions. These instructions are introduced for Bulldozer micro architecture, and not supported on Intel's processors. But when compiling kernel with CONFIG_X86_NATIVE_CPU on some AMD processor (e.g. -march=bdver2), these instructions can be used. Reported-by: Alan J. Wylie <alan(a)wylie.me.uk> Closes: https://lore.kernel.org/all/871pq06728.fsf@wylie.me.uk/ Signed-off-by: Masami Hiramatsu (Google) <mhiramat(a)kernel.org> --- arch/x86/include/asm/inat.h | 15 +++
