[PATCH 0/3] x86/ioremap: clean up the mess in xxx_is_setup_data

From: Baoquan He
Date: Thu Nov 14 2024 - 20:22:04 EST


Functions memremap_is_setup_data() and early_memremap_is_setup_data()
share completely the same process and handling, except of the
different memremap/unmap invocations. The code can be extracted and put
into a helper function __memremap_is_setup_data().

And parameter 'size' is unused in implementation of memremap_is_efi_data(),
memremap_is_setup_data and early_memremap_is_setup_data().

This patchset is made to clean them up. It sits on top of tip/x86/urgent
commit 8d9ffb2fe65a ("x86/mm: Fix a kdump kernel failure on SME system
when CONFIG_IMA_KEXEC=y")

Baoquan He (3):
x86/ioremap: introduce helper to check if physical address is in
setup_data
x86/ioremap: use helper to implement xxx_is_setup_data()
x86/mm: clean up unused parameters of functions
