Subject: [PATCH] net/mlx5: Adjust log_max_qp to be 18 at most
[ Upstream commit a6e9085d791f8306084fd5bc44dd3fdd4e1ac27b ]
The cited commit limited log_max_qp to be 17 due to FW capabilities.
Recently, it turned out that there are old FW versions that supported
more than 17, so the cited commit caused a degradation.
Thus, set the maximum log_max_qp back to 18 as it was before the
cited commit.
Fixes: 7f839965b2d7 ("net/mlx5: Update log_max_qp value to be 17 at most")

Subject: [PATCH] KVM: x86: revalidate steal time cache if MSR value changes
commit 901d3765fa804ce42812f1d5b1f3de2dfbb26723 upstream.
Commit 7e2175ebd695 ("KVM: x86: Fix recording of guest steal time
/ preempted status", 2021-11-11) open coded the previous call to
kvm_map_gfn, but in doing so it dropped the comparison between the cached
guest physical address and the one in the MSR. This cause an incorrect
cache hit if the guest modifies the steal time address while the memslots
remain the same. This can happen with kexec, in which case the steal
time data is written at the address used by the old kernel instead of
the old one.
While at it, rename the variable from gfn to gpa since it is a plain
physical address and not a right-shifted one.
