[PATCH] CPUSETS: add mems to basic usage documentation
It seems that there must be at least one node in mems and at least one CPU
in cpus in order to be able to assign tasks to a cpuset. This makes sense.
And I think it would also make sense to include a mems setting in the
basic usage section of the documentation.
I also wonder if something logged to dmsg, explaining why a write failed,
would be a good enhancement. I ended up having rummage arround in cpuset.c
in order to work out why my configuration was failing.

Currently we have a confused udelay implementation.
* __const_udelay does not accept usecs but xloops in i386 and x86_64
* our implementation requires usecs as arg
* it gets a xloops count when called by asm/arch/delay.h
Bugs related to this (extremely long shutdown times) where reported by some
x86_64 users, especially using Device Mapper.
To hit this bug, a compile-time constant time parameter must be passed -
that's why UML seems to work most times. Fix this with a simple udelay
implementation.

[ARM] 4298/1: fix memory barriers for DMA coherent and SMP platforms
This patch:
- Switches mb/rmb/wmb back to being full-blown DMBs on ARM SMP systems,
since mb/rmb/wmb are required to order Normal memory accesses as well.
- Enables the use of DMB and ISB on XSC3 (which is an ARMv5TE ISA core
but conforms to the ARMv6 memory ordering model and supports the
various ARMv6 barriers.)
- Makes DMA coherent platforms (only ixp23xx at the moment) map
mb/rmb/wmb to dmb(), as on DMA coherent platforms, DMA consistent
mappings are done as Normal mappings, which are weakly ordered.

[PATCH] holepunch: fix disconnected pages after second truncate
shmem_truncate_range has its own truncate_inode_pages_range, to free any pages
racily instantiated while it was in progress: a SHMEM_PAGEIN flag is set when
this might have happened. But holepunching gets no chance to clear that flag
at the start of vmtruncate_range, so it's always set (unless a truncate came
just before), so holepunch almost always does this second
truncate_inode_pages_range.
shmem holepunch has unlikely swap<->file races hereabouts whatever we do
(without a fuller rework than is fit for this release): I was going to skip
the second truncate in the punch_hole case, but Miklos points out that would
make holepunch correctness more vulnerable to swapoff. So keep the second
truncate, but follow it by an unmap_mapping_range to eliminate the
disconnected pages (freed from pagecache while still mapped in userspace) that
it might have left behind.
Miklos Szeredi observes that during truncation of shmem page directories,
info->lock is released to improve latency (after lowering i_size and
next_index to exclude races); but this is quite wrong for holepunching, which
receives no such protection from i_size or next_index, and is left vulnerable
to races with shmem_unuse, shmem_getpage and shmem_writepage.
Hold info->lock throughout when holepunching? No, any user could prevent
rescheduling for far too long. Instead take info->lock just when needed: in
shmem_free_swp when removing the swap entries, and whenever removing a
directory page from the level above. But so long as we remove before
scanning, we can safely skip taking the lock at the lower levels, except at
misaligned start and end of the hole.

[PATCH] holepunch: fix shmem_truncate_range punching too far
Miklos Szeredi observes BUG_ON(!entry) in shmem_writepage() triggered in rare
circumstances, because shmem_truncate_range() erroneously removes partially
truncated directory pages at the end of the range: later reclaim on pages
pointing to these removed directories triggers the BUG. Indeed, and it can
also cause data loss beyond the hole.
Fix this as in the patch proposed by Miklos, but distinguish between "limit"
(how far we need to search: ignore truncation's next_index optimization in the
holepunch case - if there are races it's more consistent to act on the whole
range specified) and "upper_limit" (how far we can free directory pages:
generally we must be careful to keep partially punched pages, but can relax at
end of file - i_size being held stable by i_mutex).

When device-mapper's DM_DEV_CREATE_CMD ioctl is called to create a new device,
dev_create()->dm_create()->alloc_dev()-> blk_queue_bounce_limit(md->queue,

blk_queue_bounce_limit(BLK_BOUNCE_ANY) calls init_emergency_isa_pool() if
blk_max_pfn < blk_max_low_pfn. This is the case on UML, but
init_emergency_isa_pool() hits BUG_ON(!isa_page_pool) because there doesn't
seem to be a dma zone on UML for mempool_create() to allocate from.
Most architectures seem to have max_low_pfn == max_pfn, but UML doesn't
because of the uml_reserved chunk it keeps for itself. From what I can see,
max_pfn and max_low_pfn don't get much use after the bootmem-allocator stops
being used anyway, except that they initialize the block layer's
blk_max_low_pfn/blk_max_pfn.

[PATCH] hrtimers: fix reprogramming SMP race
hrtimer_start() incorrectly set the 'reprogram' flag to enqueue_hrtimer(),
which should only be 1 if the hrtimer is queued to the current CPU.
Doing otherwise could result in a reprogramming of the current CPU's
clockevents device, with a timer that is not queued to it - resulting in a
bogus next expiry value.

We were only checking if there was enough space to put the int, but
left len as specified by the (malicious) user, sigh, fix it by setting
len to sizeof(val) and transfering just one int worth of data, the one
asked for.
Also check for negative len values.

mv643xx_eth: Fix use of uninitialized port_num field
In this driver, the default ethernet address is first set by by calling
eth_port_uc_addr_get() which reads the relevant registers of the
corresponding port as initially set by firmware. However that function
used the port_num field accessed through the private area of net_dev
before it was set.
The result was that one board I have ended up with the unicast address
set to 00:00:00:00:00:00 (only port 1 is connected on this board). The
problem appeared after commit 84dd619e4dc3b0b1c40dafd98c90fd950bce7bc5.
This patch fixes the bug by setting mp->port_num prior to calling
eth_port_uc_get_addr().

The tx timeout routine was waking the tx queue conditionally. However,
it must call it unconditionally since the dev_watchdog has halted the tx

atl1: remove unnecessary crc inversion
The original vendor driver contained a private ether_crc_le() function
that produced an inverted crc. When we changed to the kernel version of
ether_crc_le(), we neglected to undo the inversion. Let's do it now.

libata: IDENTIFY backwards for drive side cable detection
For drive side cable detection to work correctly, drives need to be
identified backwards such that the slave device releases PDIAG- before
the mater drive tries to detect cable type. ata_bus_probe() was fixed
by commit f31f0cc2f0b7527072d94d02da332d9bb8d7d94c but the new EH path
wasn't fixed. This patch makes new EH path do IDENTIFY backwards.
ata_dev_configure() for new devices are still performed master first.

ahci.c: walkaround for SB600 SATA internal error issue
There is a HW issue in ATI SB600 SATA that PxSERR.E should not be
set on some conditions, for example, when there is no media in SATA
CD/DVD drive or media is not ready, AHCI controller fails to execute
ATAPI commands and reports PORT_IRQ_TF_ERR, but ATI SB600 SATA
controller sets PxSERR.E at the
same time, which is not necessary.
This patch is just to ignore the INTERNAL ERROR in such case.
Without this patch, ahci error handler will report many errors as
below:
