Commit Message

Oleksii Kurochko Dec. 1, 2023, 8:48 p.m. UTC 
The header is shared between several archs so it is
moved to asm-generic.

Switch partly Arm and PPC to asm-generic/monitor.h and only
arch_monitor_get_capabilities() left in arch-specific/monitor.h.

Changes in V5:
  - Switched partly Arm and PPC to asm-generic monitor.h only
    arch_monitor_get_capabilities() left in arch-specific/monitor.h.
  - Updated the commit message.
---
Changes in V4:
 - Removed the double blank line.
 - Added Acked-by: Jan Beulich <jbeulich@suse.com>.
 - Update the commit message
---
Changes in V3:
 - Use forward-declaration of struct domain instead of " #include <xen/sched.h> ".
 - Add ' include <xen/errno.h> '
 - Drop PPC's monitor.h.
---
Changes in V2:
	- remove inclusion of "+#include <public/domctl.h>"
	- add "struct xen_domctl_monitor_op;"
	- remove one of SPDX tags.
