## Overview

In the Linux kernel, the following vulnerability has been resolved:

arm64: hibernate: pass HVC_SET_VECTORS args to the resume hvc

swsusp_arch_suspend_exit() reinstalls the restored kernel's hyp stub
vectors with an hvc, but never passes the arguments. x0 is not set to
HVC_SET_VECTORS and x1 is not set to the vector address, so the stub
dispatch falls through and returns without writing vbar_el2. EL2 is
left pointing at the trans_pgd copy of the vectors, a page that
swsusp_free() releases right after resume.

Set the arguments up the same way __hyp_set_vectors() does.

Without this fix, Vladimir was able to trigger a hang when resuming from
hibernation with CONFIG_PAGE_POISONING=y and page_poison=on.

## Remediation
