ACPI: S4: Use "platform" rather than "shutdown" mode by default

It has been reported that on some systems the functionality after a resume
from disk is limited if the system is simply powered off during the suspend
instead of using the ACPI S4 suspend (aka platform mode).

Unfortunately the default is currently to power off the system during the
suspend so the users of these systems experience problems after the resume
if they don't switch to the platform mode explicitly.  This patch makes swsusp
use the platform mode by default to avoid such situations.

Revert "r8169: mac address change support"

This reverts commit a2b98a697fa4e7564f78905b83db122824916cf9.

As per Guennadi Liakhovetski, the mac address change support code breaks
some normal uses (_without_ any address changes), and until it's all
sorted out, we're better off without it.

Says Francois:

  "Go revert it.

   Despite what I claimed, I can not find a third-party confirmation by
   email that it works elsewhere.

   It would probably be enough to remove the call to
   __rtl8169_set_mac_addr() in rtl8169_hw_start() though."

GFP_LEVEL_MASK, whereas __vmalloc_area_node does the same with

# ChangeSet
#   2006/06/22 15:05:57-07:00 neilb@suse.de
#   [PATCH] Fix dcache race during umount

#   If prune_dcache finds a dentry that it cannot free, it leaves it where it
#   is (at the tail of the list) and exits, on the assumption that some other
#   thread will be removing that dentry soon.

However as far as I see this comment is not correct: when we cannot take
s_umount rw_semaphore (for example because it was taken in do_remount) this
dentry is already extracted from dentry_unused list and we do not add it
into the list again.  Therefore dentry will not be found by prune_dcache()
and shrink_dcache_sb() and will leave in memory very long time until the
partition will be unmounted.

The patch adds this dentry into tail of the dentry_unused list.

Add __GFP_NOWARN flag to calling of __alloc_pages() in

In ia64, section size is 1 GB, this means that order 8 pages are necessary
for each section's memmap.  It is often very hard requirement under heavy
memory pressure as you know.  So, __alloc_pages() gives up allocation and
shows many noisy stack traces which means no page for each sections.
(Current my environment shows 32 times of stack trace....)

But, __kmalloc_section_memmap() calls vmalloc() after failure of it, and it
can succeed allocation of memmap.  So, its stack trace warning becomes just
noisy.  I suppose it shouldn't be shown.

[PATCH] jbd2: journal_dirty_data re-check for unmapped buffers

When running several fsx's and other filesystem stress tests, we found
cases where an unmapped buffer was still being sent to submit_bh by the
ext3 dirty data journaling code.

I saw this happen in two ways, both related to another thread doing a
truncate which would unmap the buffer in question.

Either we would get into journal_dirty_data with a bh which was already
unmapped (although journal_dirty_data_fn had checked for this earlier, the
state was not locked at that point), or it would get unmapped in the middle
of journal_dirty_data when we dropped locks to call sync_dirty_buffer.

By re-checking for mapped state after we've acquired the bh state lock, we
should avoid these races.  If we find a buffer which is no longer mapped,
we essentially ignore it, because journal_unmap_buffer has already decided
that this buffer can go away.

I've also added tracepoints in these two cases, and made a couple other

state was not locked at that point), or it would get unmapped in the middle
of journal_dirty_data when we dropped locks to call sync_dirty_buffer.

By re-checking for mapped state after we've acquired the bh state lock, we
should avoid these races.  If we find a buffer which is no longer mapped,
we essentially ignore it, because journal_unmap_buffer has already decided
that this buffer can go away.

I've also added tracepoints in these two cases, and made a couple other
tracepoint changes that I found useful in debugging this.

18 years ago[PATCH] Use min of two prio settings in calculating distress for reclaim
Martin Bligh [Sat, 28 Oct 2006 17:38:25 +0000 (10:38 -0700)]
[PATCH] Use min of two prio settings in calculating distress for reclaim

If try_to_free_pages / balance_pgdat are called with a gfp_mask specifying
GFP_IO and/or GFP_FS, they will reclaim the requisite number of pages, and the
reset prev_priority to DEF_PRIORITY (or to some other high (ie: unurgent)
value).

However, another reclaimer without those gfp_mask flags set (say, GFP_NOIO)
may still be struggling to reclaim pages.  The concurrent overwrite of
zone->prev_priority will cause this GFP_NOIO thread to unexpectedly cease
deactivating mapped pages, thus causing reclaim difficulties.

Fix this is to key the distress calculation not off zone->prev_priority, but
also take into account the local caller's priority by using
min(zone->prev_priority, sc->priority)

18 years ago[PATCH] vmscan: Fix temp_priority race
Martin Bligh [Sat, 28 Oct 2006 17:38:24 +0000 (10:38 -0700)]
[PATCH] vmscan: Fix temp_priority race

The temp_priority field in zone is racy, as we can walk through a reclaim
path, and just before we copy it into prev_priority, it can be overwritten
(say with DEF_PRIORITY) by another reclaimer.

The same bug is contained in both try_to_free_pages and balance_pgdat, but
it is fixed slightly differently.  In balance_pgdat, we keep a separate
priority record per zone in a local array.  In try_to_free_pages there is
no need to do this, as the priority level is the same for all zones that we
reclaim from.

Impact of this bug is that temp_priority is copied into prev_priority, and
setting this artificially high causes reclaimers to set distress
artificially low.  They then fail to reclaim mapped pages, when they are,
in fact, under severe memory pressure (their priority may be as low as 0).
This causes the OOM killer to fire incorrectly.

From: Andrew Morton <akpm@osdl.org>

__zone_reclaim() isn't modifying zone->prev_priority.  But zone->prev_priority
is used in the decision whether or not to bring mapped pages onto the inactive
list.  Hence there's a risk here that __zone_reclaim() will fail because
zone->prev_priority ir large (ie: low urgency) and lots of mapped pages end up
stuck on the active list.

Fix that up by decreasing (ie making more urgent) zone->prev_priority as
__zone_reclaim() scans the zone's pages.

This bug perhaps explains why ZONE_RECLAIM_PRIORITY was created.  It should be
possible to remove that now, and to just start out at DEF_PRIORITY?

[TCP] cubic: scaling error

Doug Leith observed a discrepancy between the version of CUBIC described
in the papers and the version in 2.6.18. A math error related to scaling
causes Cubic to grow too slowly.

Patch is from "Sangtae Ha" <sha2@ncsu.edu>. I validated that
it does fix the problems.

See the following to show behavior over 500ms 100 Mbit link.

[SPARC64]: Fix central/FHC bus handling on Ex000 systems.

1) probe_other_fhcs() wants to see only non-central FHC
   busses, so skip FHCs that don't sit off the root

2) Like SBUS, FHC can lack the appropriate address and
   size cell count properties, so add an of_busses[]
   entry and handlers for that.

3) Central FHC irq translator probing was buggy.  We
   were trying to use dp->child in irq_trans_init but
   that linkage is not setup at this point.

   So instead, pass in the parent of "dp" and look for
   the child "fhc" with parent "central".

[PATCH] AVR32: Use __raw MMIO access for internal peripherals

The read[bwl] and write[bwl] functions are meant for accessing PCI
devices. How this is achieved on AVR32 is unknown, as there are no
systems with a PCI bridge available yet.

On-chip peripheral access, however, should not depend on how we end
up implementing PCI access, so using __raw_read[bwl]/__raw_write[bwl]
is the right thing to do for on-chip peripherals. This patch converts
the drivers for the static memory controller, interrupt controller,
PIO controller and system manager to use __raw MMIO access.

[PATCH] AVR32: add io{read,write}{8,16,32}{be,} support

a series of macros.

Access to the (memory mapped) io space through these macros is defined to
be little endian only as little endian devices (such as PCI) are the main
consumer of IO access.  If high speed access is required,
io{read,write}{16,32}be macros are supplied to perform native big endian
