[POWERPC] Make alignment exception always check exception table

2006-11-01T04:16:04+00:00

The alignment exception used to only check the exception table for
-EFAULT, not for other errors. That opens an oops window if we can
coerce the kernel into getting an alignment exception for other reasons
in what would normally be a user-protected accessor, which can be done
via some of the futex ops. This fixes it by always checking the
exception tables.

[PATCH] pidspace: is_init()

2006-09-29T16:18:12+00:00

This is an updated version of Eric Biederman's is_init() patch.
(http://lkml.org/lkml/2006/2/6/280).  It applies cleanly to 2.6.18-rc3 and
replaces a few more instances of ->pid == 1 with is_init().

Further, is_init() checks pid and thus removes dependency on Eric's other
patches for now.

Eric's original description:

	There are a lot of places in the kernel where we test for init
	because we give it special properties.  Most  significantly init
	must not die.  This results in code all over the kernel test
	->pid == 1.

	Introduce is_init to capture this case.

	With multiple pid spaces for all of the cases affected we are
	looking for only the first process on the system, not some other
	process that has pid == 1.

[PATCH] powerpc: trivial: modify comments to refer to new location of files

2006-02-10T05:53:51+00:00

This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree.  I think this accomplises
everything wanted, though there might be a few references I missed.

[PATCH] ppc: Remove powermac support from ARCH=ppc

2006-01-15T06:30:44+00:00

This makes it possible to build kernels for PReP and/or CHRP
with ARCH=ppc by removing the (non-building) powermac support.
It's now also possible to select PReP and CHRP independently.
Powermac users should now build with ARCH=powerpc instead of
ARCH=ppc.  (This does mean that it is no longer possible to
build a 32-bit kernel for a G5.)

[PATCH] ppc: Fix ARCH=ppc build with xmon

2005-11-08T00:19:48+00:00

xmon() prototype is inconsistent between ARCH=ppc and ARCH=powerpc,
thus causing ARCH=ppc build breakage.

[PATCH] ppc32: handle access to non-present IO ports on 8xx

2005-11-07T01:37:12+00:00

This adds exception table entries for I/O instructions on and
changes MachineCheckException() slightly to cover 8xx specifics (on
8xx the MCE can be generated while executing the IO access instruction
itself, which is not the case on PowerMac's, as the comment on traps.c
details).

[PATCH] ppc: Fix build warnings in arch/ppc/kernel/traps.c

2005-11-03T05:54:10+00:00

The latest updates to bug.h generate build warnings in traps.c in
arch/ppc.  Fix print format specifiers to account for change of line type
to long from int.
