[Xen-devel] [PATCH] x86/pmtimer: Fix hvm_acpi_sleep_button behavior



Commit 19fb14622e941 "x86/pmtimer: move ACPI registers from PMTState to
hvm_domain" misconfigures pm1a_sts for hvm_acpi_sleep_button with
PWRBTN_STS instead of SLPBTN_STS, which leads to
XEN_DOMCTL_SENDTRIGGER_SLEEP causing guest powerdowns. Fix this.
