Currently, numa & prom are the users of drmem lmb walk code. Loading

In kexec case, the kernel to be loaded uses the same memory layout as

Some architectures may have special memory regions, within the given

Implement weak arch_kexec_locate_mem_hole() definition which arch code
may override, to take care of special regions, while trying to locate
a memory hole.

Since commit b3e96c0c7562 ("xen: use freeze/restore/thaw PM events for
suspend/resume/chkpt"), xenbus uses PMSG_FREEZE, PMSG_THAW and
PMSG_RESTORE events for Xen suspend. However, they're actually assigned
to xenbus_dev_suspend(), xenbus_dev_cancel() and xenbus_dev_resume()

The SNAPSHOT_SET_SWAP_AREA is supposed to be used to set the hibernation

However, it doesn't actually update the swsusp_resume_block variable. As

This series fixes PM hibernation for hvm guests running on xen hypervisor.
The running guest could now be hibernated and resumed successfully at a
later time. The fixes for PM hibernation are added to block and

Many legacy device drivers do not implement power management (PM)
functions which means that interrupts requested by these drivers stay
in active state when the kernel is hibernated.
This does not matter on bare metal and on most hypervisors because the

Guest hibernation is different from xen suspend/resume/live migration.
