Subject: [GIT PULL] Hyper-V commits for 6.4
Hi Linus,
The following changes since commit 6a8f57ae2eb07ab39a6f0ccad60c760743051026:
Linux 6.3-rc7 (2023-04-16 15:23:53 -0700)
are available in the Git repository at:
ssh://git@...olite.kernel.org/pub/scm/linux/kernel/git/hyperv/linux.git tags/hyperv-next-signed-20230424

PCI: hv: Replace retarget_msi_interrupt_params with hyperv_pcpu_input_arg (2023-04-21 21:25:23 +0000)
Note that I needed to do a merge with tip/x86/sev because some of
Michael's patches were merged into that branch first. I've written down
the rationale in the merge commit.
This PR can conflict with sysctl-next, because both branches modified
VMBus code. A correct resolution can be found here:
https://lore.kernel.org/linux-next/20230424154742.131094-1-broonie@kernel.org/
Although the resolution is empty, it is correct, because Long rebased
his patch multiple times on both linux-next and linux-hyperv, the patch
ended up containing the same changes as Luis' patch.
