[Xen-devel] [PATCH v3 03/22] xl: parsing code movement

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Code movement in preparation for making the bootloader,
bootloader_args, nested_hvm and timer_mode fields shared between all
guests types. While moving the code, limit the line-length to 80
columns.

No functional change.
