You are right, I misread the git history. Can you fix it up when applying the
patch, or should I resend it?



I can fix it up, no worries.

Minor thing, but should the Fixes be c46f3405692d ("tpm: Reserve the TPM final

[PATCH] efi/tpm: fix section mismatch warning

2020-04-29 Thread Arnd Bergmann
Building with gcc-10 causes a harmless warning about a section mismatch:

WARNING: modpost: vmlinux.o(.text.unlikely+0x5e191): Section mismatch in 
reference from the function tpm2_calc_event_log_size() to the function 
.init.text:early_memunmap()
The function tpm2_calc_event_log_size() references
the function __init early_memunmap().
This is often because tpm2_calc_event_log_size lacks a __init
annotation or the annotation of early_memunmap is wrong.

Add the missing annotation.
