Just to clarify, we have the following 3 upstream (and soon to be upstream) versions:
v1: pre-d794734c9bbf kernels
v2: d794734c9bbf x86/mm/ident_map: Use gbpages only where full GB page should be mapped.
v3: c567f2948f57 Revert "x86/mm/ident_map: Use gbpages only where full GB page should be mapped."
Where v1 and v3 ought to be the same in behavior.
So how does the failure matrix look like on your systems? Is my
understanding accurate:
regular boot | regular kexec | nogbpages boot | nogbpages kexec boot
------------------------|---------------------------------------------------
v1: OK | OK | OK | FAIL
v2: OK | FAIL | FAIL | FAIL
Slight correction:
regular boot | regular kexec | nogbpages boot | nogbpages kexec boot
-----------------|---------------|----------------|------------------
v1: OK | OK | OK | FAIL
v2: OK | FAIL | OK | FAIL
