Subject: [PATCH 0/4] arm64: kexec: translate relocate_kernel.S to C languange
Date: Thu, 28 Mar 2024 19:56:50 +0800 [thread overview]
Message-ID: <20240328115656.24090-1-piliu@redhat.com> (raw)
Translate relocate_kernel.S to C languange to make it more readable.
The relocate_kernel.c is PIE, but I am not sure whether it should locate in
kernel/pi, which runs check on the PIE code. (I can correct it in next
version)
