Subject: How does kdump deal with trampoline allocation?
Date: Mon, 27 Dec 2010 12:31:20 -0800	[thread overview]
Message-ID: <4D18F798.4010708@zytor.com> (raw)

Hi guys,

I'm planning a major overhaul of the trampoline allocation in x86, and
I'm trying to understand how kdump deals with it.  The trampoline has to
be allocated in low memory (< 1 MiB) and obviously that doesn't include
the kdump area at all.
