[PATCH 5.10 139/563] arm64: lib: Annotate {clear, copy}_page() as position-independent

[Greg Kroah-Hartman]

From: Will Deacon <will@xxxxxxxxxx>

[ Upstream commit 8d9902055c57548bb342dc3ca78caa21e9643024 ]

clear_page() and copy_page() are suitable for use outside of the kernel
address space, so annotate them as position-independent code.
