Subject: [GIT PULL] integrity additional change v5.8 (#2)

Hi Linus,

Prior to Linux 5.8 the SHA1 "boot_aggregate" value was padded with 0's
and extended into the other TPM 2.0 banks.  Included in the Linux 5.8
open window, TPM 2.0 PCR bank specific "boot_aggregate" values (PCRs 0
- 7) are calculated and extended into the TPM banks.

Distro releases are now shipping grub2 with TPM support, which extend
PCRs 8 & 9.  I'd like for PCRs 8 & 9 to be included in the new
"boot_aggregate" calculations.  For backwards compatibility, PCRs 8 &
9 are not included in the SHA1 TPM bank "boot_aggregate" calculation.

I'd appreciate your merging this additional change.

thanks,

Mimi
