commit

replaced CHUNK_BLOCK_RATIO() by the same text that was

The result is that 'chunks' is often too small by 1,

So use the correct replacement, and get rid of CHUNK_BLOCK_RATIO

vfs: make word-at-a-time accesses handle a non-existing page
It turns out that there are more cases than CONFIG_DEBUG_PAGEALLOC that
can have holes in the kernel address space: it seems to happen easily
with Xen, and it looks like the AMD gart64 code will also punch holes
dynamically.
Actually hitting that case is still very unlikely, so just do the
access, and take an exception and fix it up for the very unlikely case
of it being a page-crosser with no next page.
And hey, this abstraction might even help other architectures that have
other issues with unaligned word accesses than the possible missing next
page. IOW, this could do the byte order magic too.
Peter Anvin fixed a thinko in the shifting for the exception case.

Merge tag 'for-usb-next-2012-05-03' of git://git./linux/kernel/git/sarah/xhci into usb-next
xhci: isoc, Intel xHCI, and suspend races.
Hi Greg,
Here's some xHCI fixes that should be queued for 3.5.
The first patch builds on Alan Stern's 3.4 patch to close the suspend and port
event race conditions. It's marked for 3.4 stable, since that's where Alan's
patch landed. The second patch fixes an incorrect error code that the xHCI
driver would return when an isochronous transfer error occurred.
The third and fourth patches fix issues seen on Intel xHCI host controllers.
The third patch fixes a dead port issue that was seen on the Panther Point
EHCI/xHCI host when CONFIG_USB_XHCI_HCD was turned off. The ports were being
switched over to xHCI, even though the xHCI driver was never even built. The
fourth patch adds support for the EHCI to xHCI port switchover for the upcoming
Intel Lynx Point chipset.
As I said, there's nothing here that's terribly urgent, and these patches can
wait a couple weeks for the 3.5 merge window.
Thanks,
Sarah Sharp

xhci: Add Lynx Point to list of Intel switchable hosts.
The upcoming Intel Lynx Point chipset includes an xHCI host controller
that can have ports switched from the EHCI host controller, just like
the Intel Panther Point xHCI host. This time, ports from both EHCI
hosts can be switched to the xHCI host controller. The PCI config
registers to do the port switching are in the exact same place in the
xHCI PCI configuration registers, with the same semantics.
Hooray for shipping patches for next-gen hardware before the current gen
hardware is even available for purchase!

If the user chooses to say "no" to CONFIG_USB_XHCI_HCD on a system

will never load. The ports will be powered off and seem "dead" to the

Fix this by only switching the ports over if CONFIG_USB_XHCI_HCD is

usb-xhci: Handle COMP_TX_ERR for isoc tds
While testing unplugging an UVC HD webcam with usb-redirection (so through
usbdevfs), my userspace usb-redir code was getting a value of -1 in
iso_frame_desc[n].status, which according to Documentation/usb/error-codes.txt
is not a valid value.
The source of this -1 is the default case in xhci-ring.c:process_isoc_td()
adding a kprintf there showed the value of trb_comp_code to be COMP_TX_ERR
in this case, so this patch adds handling for that completion code to
process_isoc_td().
This was observed and tested with the following xhci controller:
1033:0194 NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04)
Note: I also wonder if setting frame->status to -1 (-EPERM) is the best we can
do, but since I cannot come up with anything better I've left that as is.

cifs - check S_AUTOMOUNT in revalidate
When revalidating a dentry, if the inode wasn't known to be a dfs
entry when the dentry was instantiated, such as when created via
->readdir(), the DCACHE_NEED_AUTOMOUNT flag needs to be set on the
dentry in ->d_revalidate().
The false return from cifs_d_revalidate(), due to the inode now
being marked with the S_AUTOMOUNT flag, might not invalidate the
dentry if there is a concurrent unlazy path walk. This is because
the dentry reference count will be at least 2 in this case causing
d_invalidate() to return EBUSY. So the asumption that the dentry
will be discarded then correctly instantiated via ->lookup() might

libata: init ata_print_id to 0

+ata6: DUMMY
+ata7: SATA max UDMA/133 abar m2048@0xf9fff000 port 0xf9fff380 irq 47
The change of numbering comes from commit
85d6725b7c0d7e3f ("libata:
make ata_print_id atomic") that changed lines like
ap->print_id = ata_print_id++;
to
ap->print_id = atomic_inc_return(&ata_print_id);
As the latter behaves like ++ata_print_id, we must initialize
it to zero to start the numbering from one.

libata: skip old error history when counting probe trials
Commit d902747("[libata] Add ATA transport class") introduced
ATA_EFLAG_OLD_ER to mark entries in the error ring as cleared.
But ata_count_probe_trials_cb() didn't check this flag and it still
counts the old error history. So wrong probe trials count is returned
and it causes problem, for example, SATA link speed is slowed down from
3.0Gbps to 1.5Gbps.
Fix it by checking ATA_EFLAG_OLD_ER in ata_count_probe_trials_cb().

WakeOnLan was broken in this driver because gp->asleep_wol is a 1-bit

gp->asleep_wol remains 0 and the machine never wakes up. Fixed by casting
gp->wake_on_lan to bool. Tested on an iBook G4.

tcp: change tcp_adv_win_scale and tcp_rmem[2]
tcp_adv_win_scale default value is 2, meaning we expect a good citizen
skb to have skb->len / skb->truesize ratio of 75% (3/4)
In 2.6 kernels we (mis)accounted for typical MSS=1460 frame :
1536 + 64 + 256 = 1856 'estimated truesize', and 1856 * 3/4 = 1392.
So these skbs were considered as not bloated.
With recent truesize fixes, a typical MSS=1460 frame truesize is now the
more precise :
2048 + 256 = 2304. But 2304 * 3/4 = 1728.
So these skb are not good citizen anymore, because 1460 < 1728
(GRO can escape this problem because it build skbs with a too low
truesize.)
This also means tcp advertises a too optimistic window for a given
allocated rcvspace : When receiving frames, sk_rmem_alloc can hit
sk_rcvbuf limit and we call tcp_prune_queue()/tcp_collapse() too often,
especially when application is slow to drain its receive queue or in
case of losses (netperf is fast, scp is slow). This is a major latency
source.
We should adjust the len/truesize ratio to 50% instead of 75%
This patch :
1) changes tcp_adv_win_scale default to 1 instead of 2
2) increase tcp_rmem[2] limit from 4MB to 6MB to take into account
better truesize tracking and to allow autotuning tcp receive window to
reach same value than before. Note that same amount of kernel memory is
consumed compared to 2.6 kernels.

drop_monitor: prevent init path from scheduling on the wrong cpu
I just noticed after some recent updates, that the init path for the drop
monitor protocol has a minor error. drop monitor maintains a per cpu structure,
that gets initalized from a single cpu. Normally this is fine, as the protocol
isn't in use yet, but I recently made a change that causes a failed skb
allocation to reschedule itself . Given the current code, the implication is
that this workqueue reschedule will take place on the wrong cpu. If drop
monitor is used early during the boot process, its possible that two cpus will
access a single per-cpu structure in parallel, possibly leading to data
corruption.
This patch fixes the situation, by storing the cpu number that a given instance
of this per-cpu data should be accessed from. In the case of a need for a
reschedule, the cpu stored in the struct is assigned the rescheule, rather than
the currently executing cpu
Tested successfully by myself.
