Available here are patches to Paul Mackerras's latest (as of Sunday
November 28, 1999, CST) development (unstable) PPC Linux kernel mirror.
Get the code with "rsync -arvuz samba.anu.edu.au::linux-pmac-devel <tgtdir>"
where <tgtdir> is where you want your source tree to end up.

Then apply these patches:

all.patch:
	All of the below in one hunk.

chipsfb.c.patch:

	[linux/drivers/video/chipsfb.c]

	Changed chipsfb driver to store some display_info data only
	when CONFIG_FB_COMPAT_XPMAC is defined (and not as it was previously
	enabled--when _either_ CONFIG_PMAC_PBOOK or ...COMPAT_XPMAC).

	*** THIS PATCH IS UNTESTED *** ... I made these changes so I could
	compile chipsfb.c with my configuration, which enables 
	CONFIG_PMAC_PBOOK, but does not need Xpmac compatability.

hfs.file.c.patch:

	[linux/fs/hfs/file.c]

	Synced hfs code with code from Linus's 2.3.28 tree, which simply
	removes the call to update_vm_cache().

	*** HFS SEEMS BROKEN *** ... HFS works for _simple_ operations	
	with the kernels built from this code.  Mounts (ro and rw) work,
	file cp works, things like mv do NOT.  Don't try it unless you 
	really like xmon.

	I don't know if HFS has just been neglected through kernel 2.3,
	or if it's been this way for a while.

keyboard.h.patch:

	[linux/include/asm-ppc/keyboard.h]

	My version of this file came in just about half-baked.
	Added missing kbd_init_hw() function, cleaned up some
	stray chunks of code elsewhere in the file.

CREDITS.patch:

	Just tacked myself in there for the changes to keyboard and
	HFS, both of which I'd like to devote some of my time to 
	make work reliably on my PowerBook.  :)
