Ian Campbell a84c4f75e5 [LINUX] Kexec: Ensure that pages allocated for kexec have MFNs which are within 
the required limits.

Previously we were lucky since most dom0 pages would be low enough but now Xen
is more aggressive in giving out higher MFNs when it can.

kfraser@localhost.localdomain e260cd0a07 The Xen console intercepts ^O and prevents it from propagating 
through to the guest.  However, ^O is a useful key in bash and in
Emacs.  This patch changes the console to pass a single ^O
through to the guest when it is pressed twice.

kfraser@localhost.localdomain ac4fb3c4ec pci back: Various fixes. 
- remove superfluous call to pciback_field_is_dup()
- fix a variable type mismatch in pciback_field_is_dup()
- make readability improvements by using the OFFSET macro
- revises quirk data output via the sysfs quirks node so that
- displayed offset information includes base_offset.

Thanks to Jambunathan K. for giving such specific bug diagnosis.

kfraser@localhost.localdomain 63d7a82fae linux: Prefer testing io_bitmap_ptr to the TIF_IO_BITMAP. 
Former is safer (in case TIF_IO_BITMAP is out-of-sync with actual
existence of an I/O bitmap for this process) and more readable, and
probably results in faster code too.
