[PATCH 0/8] arm64: Expose compat Armv8 AArch32 features

[Amit Daniel Kachhap]

Hi All,

This series advertises the Armv8 AArch32 features in arm64 kernel in
compat mode. A similar series adding such features (fphp, asimdhp, dp,
fhm, bf16, i8mm, sb and ssbs) in arm kernel was posted earlier.

The entire series is divided feature wise as present in Armv8 manual.
The details of these features can be found in Armv8 architecture
reference manual available from
https://developer.arm.com/documentation/ddi0487/gb/?lang=en

All the changes have been tested on Arm FVP Base Revc model after adding
necessary model parameters. The different hwcaps added are visible in
/proc/cpuinfo in PER_LINUX32 personality mode.

The series is based on Linux 6.1-rc1.

Thanks,
Amit Daniel
