Hello All,
OK, I've discovered a mechanism of the issue.
It is because of `d->max_pages = ~0U;` in a `construct_dom0()`.
When I do vcpu-pin, libxl updates memory nodes in xenstore for Dom0.
Then kernel watch sees those changes and trying to set new
paging_max_paddr_bits() has an invalid use of IS_ENABLED(): instead of
IS_ENABLED(CONFIG_BIGMEM) it is using IS_ENABLED(BIGMEM). Fix that.

Initialize the grant tab in a dedicated function. This will enable
using it for PVH guests, too.
Call the new function from grub_machine_init() as this will later
be common between Xen PV and Xen PVH mode.

Move the printing out of the switch statement in order to have the

In debug builds the hypervisor will deliberately clobber processed
elements of the multicall structure. In order to ease diagnostic data
printout in the affected guest only clobber elements which didn't

Instead of passing the RSDP address for Xen PVH guests from grub2 to
the kernel in setup_header move it into the non-legacy part of the
boot_params structure.
This patch series should be applied rather sooner than later in order
to avoid shipping linux 4.20 with a corky boot protocol.

Initialize the grant tab in a dedicated function. This will enable
using it for PVH guests, too.
Call the new function from grub_machine_init() as this will later
be common between Xen PV and Xen PVH mode.

V2: update commit message
Add all usable memory regions to grub memory management and add the
needed mmap iterate code, which will be used by grub core (e.g.
grub-core/lib/relocator.c or grub-core/mmap/mmap.c).
As we are running in 32-bit mode don't add memory above 4GB.
