      xen/setup: Don't relocate p2m over existing one · 993c8687
      Ross Lagerwall authored 
      BugLink: http://bugs.launchpad.net/bugs/1681862

commit 7ecec850 upstream.

When relocating the p2m, take special care not to relocate it so
that is overlaps with the current location of the p2m/initrd. This is
needed since the full extent of the current location is not marked as a
reserved region in the e820.

This was seen to happen to a dom0 with a large initial p2m and a small
reserved region in the middle of the initial p2m.

This patch adds the vendor release version on the Exar USB serial
device. Features include:
1. Fix for RX fail after wake-up from sleep (S3/S4)
2. Removes unnecessary debug messages

Changelog:

Version 1B, 11/6/2015
Fixed Bug: The conditional logic to support kernel 3.9 was
incorrect(line 396 in xr_usb_serial_common.c).

Version 1A, 1/9/2015
This driver will work with any USB UART function in these Exar devices:
	XR21V1410/1412/1414
	XR21B1411
	XR21B1420/1422/1424
