Merge tag 'kcfi-v6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull kcfi updates from Kees Cook:
"This replaces the prior support for Clang's standard Control Flow
Integrity (CFI) instrumentation, which has required a lot of special
conditions (e.g. LTO) and work-arounds.

The new implementation ("Kernel CFI") is specific to C, directly
designed for the Linux kernel, and takes advantage of architectural
features like x86's IBT. This series retains arm64 support and adds
x86 support.

GCC support is expected in the future[1], and additional "generic"
architectural support is expected soon[2].

Summary:

- treewide: Remove old CFI support details

- arm64: Replace Clang CFI support with Clang KCFI support

- x86: Introduce Clang KCFI support"

arm64: Add CFI error handling

With -fsanitize=kcfi, CFI always traps. Add arm64 support for handling CFI
failures. The registers containing the target address and the expected type
are encoded in the first ten bits of the ESR as follows:

- 0-4: n, where the register Xn contains the target address
- 5-9: m, where the register Wm contains the type hash

This produces the following oops on CFI failure (generated using lkdtm):
