[Xen-devel] [PATCH] libxl: correct bug in domain builder regarding page tables for pvh

[Juergen Gross <jgross@xxxxxxxx>]

Commit 81a76e4b12961a9f54f5021809074196dfe6dbba ("libxc: rework of
domain builder's page table handler") dropped a special case for pvh
resulting in page tables being mapped read-only. This led to a panic
of the domain in early boot.

Correct this error.
