Mikael Pettersson [Mon, 1 May 2006 19:16:18 +0000]
[PATCH] x86_64: make PC Speaker driver work

The PC Speaker driver's ->probe() routine doesn't even get called in the
64-bit kernels.  The reason for that is that the arch code apparently has
to explictly add a "pcspkr" platform device in order for the driver core to
call the ->probe() routine.  arch/i386/kernel/setup.c unconditionally adds
a "pcspkr" device, but the x86_64 kernel has no code at all related to the
PC Speaker.

The patch below copies the relevant code from i386 to x86_64, which makes
the PC Speaker work for me on x86_64.

Christoph Lameter [Mon, 1 May 2006 19:16:08 +0000]
[PATCH] page migration: Fix fallback behavior for dirty pages

Currently we check PageDirty() in order to make the decision to swap out
the page.  However, the dirty information may be only be contained in the
ptes pointing to the page.  We need to first unmap the ptes before checking
for PageDirty().  If unmap is successful then the page count of the page
will also be decreased so that pageout() works properly.

This is a fix necessary for 2.6.17.  Without this fix we may migrate dirty
pages for filesystems without migration functions.  Filesystems may keep
pointers to dirty pages.  Migration of dirty pages can result in the
filesystem keeping pointers to freed pages.

Unmapping is currently not be separated out from removing all the
references to a page and moving the mapping.  Therefore try_to_unmap will
be called again in migrate_page() if the writeout is successful.  However,
it wont do anything since the ptes are already removed.

The coming updates to the page migration code will restructure the code
so that this is no longer necessary.

Paolo 'Blaisorblade' Giarrusso [Mon, 1 May 2006 19:16:05 +0000]
[PATCH] uml: cleanup unprofile expression and build infrastructure

*) Rather than duplicate in various buggy ways the application of
   CFLAGS_NO_HARDENING and UNPROFILE (which apply to the same files),
   centralize it in Makefile.rules.  UNPROFILE_OBJS mustn't be listed in
   USER_OBJS but are compiled as such.

I've also verified that unprofile didn't work in the current form, because we
set _c_flags directly (using CFLAGS and not USER_CFLAGS, which is wrong),
which is normally used by c_flags, but we also override c_flags for all
USER_OBJS, and there we don't call unprofile.

Instead it only worked for unmap.o, the only one which wasn't a USER_OBJ.

We need to set c_flags (which is not a public Kbuild API) to clear a lot of
compilation flags like -nostdinc which Kbuild forces on everything.

*) Rather than $(CFLAGS_$(notdir $@)), which expands to CFLAGS_anObj.s when
   building "anObj.s", use $(CFLAGS_$(*F).o) which always accesses
   CFLAGS_anObj.o, like done by Kbuild.

*) Make c_flags apply to all targets having the same basename, rather than
   listing .s, .i, .lst and .o, with the use (which I tested) of

$(USER_OBJS:.o=.%): c_flags = ...

and of

 -      $(obj)/unmap.c: _c_flags = ...
 +      $(obj)/unmap.%: _c_flags = ...

NeilBrown [Mon, 1 May 2006 19:15:47 +0000]
[PATCH] md: Fix 'rdev->nr_pending' count when retrying barrier requests

When retrying a failed BIO_RW_BARRIER request, we need to keep the reference
in ->nr_pending over the whole retry.  Currently, we only hold the reference
if the failed request is the *last* one to finish - which is silly, because it
would normally be the first to finish.

So move the rdev_dec_pending call up into the didn't-fail branch.  As the rdev
isn't used in the later code, calling rdev_dec_pending earlier doesn't hurt.

Jens Axboe [Mon, 1 May 2006 17:59:03 +0000]
[PATCH] pipe: introduce ->pin() buffer operation

The ->map() function is really expensive on highmem machines right now,
since it has to use the slower kmap() instead of kmap_atomic(). Splice
rarely needs to access the virtual address of a page, so it's a waste
of time doing it.

Introduce ->pin() to take over the responsibility of making sure the
page data is valid. ->map() is then reduced to just kmap(). That way we
can also share a most of the pipe buffer ops between pipe.c and splice.c

- Only allow full pages to go to the page cache.
- Check page != buf->page instead of using PIPE_BUF_FLAG_STOLEN.
- Remember to clear 'stolen' if add_to_page_cache() fails.

And as a cleanup on that:

- Make the bottom fall-through logic a little less convoluted. Also make
  the steal path hold an extra reference to the page, so we don't have

Gary Zambrano [Sun, 30 Apr 2006 01:59:13 +0000]
[TG3]: Add reset_phy parameter to chip reset functions

Add a reset_phy parameter to tg3_reset_hw() and tg3_init_hw(). With
the full chip reset during MAC address change, the automatic PHY reset
during chip reset will cause a link down and bonding will not work
properly as a result. With this reset_phy parameter, we can do a chip
reset without link down when changing MAC address or MTU.

[TG3]: Reset chip when changing MAC address

Do the full chip reset when changing MAC address if ASF is enabled.

ASF sometimes uses a different MAC address than the driver. Without
the reset, the ASF MAC address may be overwritten when the driver's

that process I found this bug in the IP ID selection code in xfrm4_output.c.

At that point dst is still the xfrm_dst for the current SA which
represents an internal flow as far as the IPsec tunnel is concerned.
Since the IP ID is going to sit on the outside of the encapsulated
