[PATCH v2 0/8] Initial implementation of kdump for ARM

[ext-mika.1.westerberg@nokia.com (Mika Westerberg)]

Hello,

This is re-send of the series. I didn't receive any comments on this but we
found few minor things during in-house review which are incorporated.

Changes to v1:
	- corrected kernel-doc for crash_setup_regs()
	- check return value of ioremap() in copy_oldmem_page()

Changes to RFC version:
	- crash_setup_regs() uses Russell's suggestion for saving registers
	- copy_oldmem_page() code is changed to use ioremap()
	- there is no need for special 'mem=' parameters

I've tested this on N900 and beagleboard.

Thanks,
Mw
