Subject: -mm swsusp: fix highmem handling
Date: Thu, 29 Jul 2004 00:23:00 +0200 [thread overview]
Message-ID: <20040728222300.GA16671@elf.ucw.cz> (raw)
Hi!
Swsusp was not restoring highmem properly. I did not find a nice place
where to restore it, through, so it went to swsusp_free.
I'm not sure why you are saving state before
save_processor_state. swsusp_arch_resume will overwrite this,
anyway. Is it to make something balanced?
Pavel
