Subject: [PATCH 1/8] lguest: Kconfig and headers
Date: Mon, 12 Feb 2007 14:44:54 +1100	[thread overview]
Message-ID: <1171251894.10409.26.camel@localhost.localdomain> (raw)
In-Reply-To: <1171251770.10409.23.camel@localhost.localdomain>

Unfortunately, we don't have the build infrastructure for "private"
asm-offsets.h files, so there's a not-so-neat include in
arch/i386/kernel/asm-offsets.c.

The four headers are:
asm/lguest.h:
	Things the guest needs to know (hypercall numbers, etc).
asm/lguest_device.h:
	Things lguest devices need to know (lguest bus registration)
asm/lguest_user.h:
	Things that the lguest userspace utility needs (/dev/lguest
	and some devices)
arch/i386/lguest/lg.h:
	Internal header for the lg module (which consists of 8 files).
