Re: [Xen-devel] [PATCH for-4.12 4/8] xen/arm: domain_build: Don't switch to the guest P2M when copying data

Until recently, kernel/initrd/dtb were loaded using guest VA and
therefore requiring to restore temporarily the P2M. This reworked in a
series of commits (up to 9292086 "xen/arm: domain_build: Use
copy_to_guest_phys_flush_dcache in dtb_load") to use a guest PA.

This will also help a follow-up patch which will require
p2m_{save,restore}_state to work in pair to workaround an erratum.
