sh: Move entry point code to .text.head.

2007-07-20T08:40:03+00:00

Follow Al Viro's m68k change from l-k:

	i.e. tell modpost that entry point code (that has to be outside
	of .init.text for external reasons) is OK to refer to .init.*

Shuts up some section mismatch warnings from modpost.

define new percpu interface for shared data

2007-07-19T17:04:44+00:00

per cpu data section contains two types of data.  One set which is
exclusively accessed by the local cpu and the other set which is per cpu,
but also shared by remote cpus.  In the current kernel, these two sets are
not clearely separated out.  This can potentially cause the same data
cacheline shared between the two sets of data, which will result in
unnecessary bouncing of the cacheline between cpus.

One way to fix the problem is to cacheline align the remotely accessed per
cpu data, both at the beginning and at the end.  Because of the padding at
both ends, this will likely cause some memory wastage and also the
interface to achieve this is not clean.

This patch:

Moves the remotely accessed per cpu data (which is currently marked
as ____cacheline_aligned_in_smp) into a different section, where all the data
elements are cacheline aligned. And as such, this differentiates the local
only data and remotely accessed data cleanly.

sh: Align .machvec.init section on a 4-byte boundary.

2007-06-08T02:43:41+00:00

.machvec.init can be misaligned with the recent machvec changes,
forcibly align it on the boundary that it expects, as before.

sh: Fixup machvec support.

2007-06-08T02:43:37+00:00

This fixes up much of the machvec handling, allowing for it to be
overloaded on boot. Making practical use of this still requires
some Kconfig munging, however.

all-archs: consolidate .data section definition in asm-generic

2007-05-19T07:11:57+00:00

With this consolidation we can now modify the .data
section definition in one spot for all archs.

sh: generic BUG() support.

2007-05-07T02:10:53+00:00

Wire up GENERIC_BUG for SH. This moves off of the special bug
frame and on to the generic struct bug_entry. Roughly the same
semantics are retained, and we can kill off some of the verbose
BUG() reporting code.

[PATCH] x86: Allow percpu variables to be page-aligned

2007-05-02T17:27:12+00:00

Let's allow page-alignment in general for per-cpu data (wanted by Xen, and
Ingo suggested KVM as well).

Because larger alignments can use more room, we increase the max per-cpu
memory to 64k rather than 32k: it's getting a little tight.

sh: Use L1_CACHE_BYTES for .data.cacheline_aligned.

2007-03-05T05:13:26+00:00

Previously this was using a hardcoded 32, use L1_CACHE_BYTES for
cacheline alignment instead.
