Subject: [GIT PULL] Please pull powerpc/linux.git powerpc-6.7-1 tag
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256
Hi Linus,
Please pull powerpc updates for 6.7.
There's one conflict, where we added Documentation/powerpc/kvm-nested.rst while
upstream moved Documentation/powerpc to Documentation/arch/powerpc. Resolution
is just to add it in the new location.
cheers
