Applied the first three to arm64 (for-next/lpa2-prep):
[01/41] arm64: kernel: Disable latent_entropy GCC plugin in early C runtime
https://git.kernel.org/arm64/c/3dfdc2750c6c
[02/41] arm64: mm: Take potential load offset into account when KASLR is off
https://git.kernel.org/arm64/c/a22fc8e102dc
[03/41] arm64: mm: get rid of kimage_vaddr global variable
https://git.kernel.org/arm64/c/376f5a3bd7e2
Applied the idreg-override part to arm64 (for-next/early-idreg-overrides):
[14/41] arm64: idreg-override: Omit non-NULL checks for override pointer
https://git.kernel.org/arm64/c/cbc59c9a4e57
[15/41] arm64: idreg-override: Prepare for place relative reloc patching
https://git.kernel.org/arm64/c/01fd29092a35
[16/41] arm64: idreg-override: Avoid parameq() and parameqn()
https://git.kernel.org/arm64/c/dc3f5aae0638
[17/41] arm64: idreg-override: avoid strlen() to check for empty strings
https://git.kernel.org/arm64/c/bcf1eed3f8a0
[18/41] arm64: idreg-override: Avoid sprintf() for simple string concatenation
https://git.kernel.org/arm64/c/060260a6be47
[19/41] arm64: idreg-override: Avoid kstrtou64() to parse a single hex digit
https://git.kernel.org/arm64/c/ea48626f8f0e
[20/41] arm64/kernel: Move 'nokaslr' parsing out of early idreg code
https://git.kernel.org/arm64/c/50f176175e96
