[GIT PULL] KVM/riscv fixes for 6.16 take #2

[GIT PULL] KVM/riscv fixes for 6.16 take #2

[Anup Patel]

Hi Paolo,

We have two more fixes for the 6.16 kernel. The first one
fixes an issue reported by Canonical [1] which turned-out
to be an issue related to timer cleanup when exiting to
user-space. The second fix addresses a race-condition
in updating HGEIE CSR when IMSIC VS-files are in-use.

Please pull.

Regards,
Anup
