[GIT PULL] KVM/arm64 fixes for 6.16, take #4

[GIT PULL] KVM/arm64 fixes for 6.16, take #4

[Marc Zyngier]

Paolo,

Another week, another set of fixes. Nothing major this time: allow
pKVM to fail to initialise without taking the host down, make sure we
are not mapping too much in the host S2 (another pKVM special), and a
brown-paper-bag quality bug fix on the nested GICv3 emulation.

Please pull,

	M.

The following changes since commit 04c5355b2a94ff3191ce63ab035fb7f04d036869:

  KVM: arm64: VHE: Centralize ISBs when returning to host (2025-06-19 13:34:59 +0100)

Done now, thanks!  Note that in the meanwhile git:// is not working
anymore, so you probably want https:// in there.

Really? That's... odd. Was this announced one way or another? I can
definitely use git:// from where I seat:

What's occurring on your side?

And it works now for me too, so it must have been a fluke on
git.kernel.org's side.
