Currently, distros like Fedora/RHEL have enabled CONFIG_IMA_KEXEC by
default. This makes kexec/kdump kernel always fail to boot up on SME
platform because of a code bug. By debugging, the root cause is found
out and bug is fixed with this patchset.
Changelog:
v2->v3:
=======
- Add how the miscaculation is caused into patch 2 log according to
Tom's suggestion.
- Add Tom's tag.
v1->v2:
=======
- Add patch 1 to clean up the confusing local varibale naming because
people may mix up the local variable 'size' with the passed in parameter
in function early_memremap_is_setup_data(). Suggested by Dave and Tom
during v1 patch reviewing.
Baoquan He (2):
x86/mm: rename the confusing local variable in
early_memremap_is_setup_data()
x86/mm/sme: fix the kdump kernel breakage on SME system when
CONFIG_IMA_KEXEC=y
