bb15e7f286 ibmaem: don't query the entire sensor repository when reading energy meter
Currently, all sensors are read when the energy meter is queried via
sysfs.  This introduces a considerable amount of delay and variation in
the sysfs reading, which is not desirable when trying to profile energy
use.  Therefore, read only the energy meters when a sysfs query comes in
for them, and don't cache the results so that we always get the latest
reading.

9c5413eac5 ibmaem: prevent infinite probing loop on x3650 M2 systems
On older machines, probing for a nonexistent AEM interface returned an
IPMI error; when we saw this, we'd stop probing.  On the x3650 M2 and
(presumably) later, we are returned a value indicating success and a
buffer full of garbage or zeroes.  This causes the probe function to run
in an infinite loop.  To fix this, we add one last check--if the
interface number we're looking for is higher than the number of
interfaces that AEM claims to have, stop probing.

4ef664b5bc abituguru3: prefer DMI probing to manual probing
Previously the driver was only using DMI to prevent smbus probing on
non-Abit motherboards.  However, since the manual probing method is
brittle and prone to failure on some Abit motherboards (esp.  the Abit
IP35 Pro) it is better to use DMI to also read the board name and then
decide whether or not to probe the bus.

At the moment, we do not have a list of valid DMI name strings to use
for existing and supported motherboards.  This patch only implements DMI
probing for the IP35 Pro.  For motherboards that can not yet use DMI
probing, a warning will be printed to the kernel log asking those users
to email me their dmidecode output.

The existing manual probing mechanism will be used if CONFIG_DMI is not
enabled, if DMI probing fails (for DMI-unsupported motherboards), or if
DMI probing fails and the "force" option is set (for DMI-supported
motherboards).  Ideally in the longer term this manual probing method
would be removed.

This patch should be safe to apply as it does not change the probing
behaviour for most of the supported motherboards, just the IP35 Pro,
which already has regressions filed against it in 2.6.26.

627240aaa9 bootmem allocator: alloc_bootmem_core(): page-align the end offset
This is the minimal sequence that jams the allocator:

void *p, *q, *r;
p = alloc_bootmem(PAGE_SIZE);
q = alloc_bootmem(64);
free_bootmem(p, PAGE_SIZE);
p = alloc_bootmem(PAGE_SIZE);
r = alloc_bootmem(64);

after this sequence (assuming that the allocator was empty or page-aligned
before), pointer "q" will be equal to pointer "r".

What's hapenning inside the allocator:
p = alloc_bootmem(PAGE_SIZE);
in allocator: last_end_off == PAGE_SIZE, bitmap contains bits 10000...
q = alloc_bootmem(64);
in allocator: last_end_off == PAGE_SIZE + 64, bitmap contains 11000...
free_bootmem(p, PAGE_SIZE);
in allocator: last_end_off == PAGE_SIZE + 64, bitmap contains 01000...
p = alloc_bootmem(PAGE_SIZE);
in allocator: last_end_off == PAGE_SIZE, bitmap contains 11000...
r = alloc_bootmem(64);

and now:

it finds bit "2", as a place where to allocate (sidx)

it hits the condition

if (bdata->last_end_off && PFN_DOWN(bdata->last_end_off) + 1 == sidx))
start_off = ALIGN(bdata->last_end_off, align);

-you can see that the condition is true, so it assigns start_off =
ALIGN(bdata->last_end_off, align); (that is PAGE_SIZE) and allocates
over already allocated block.

With the patch it tries to continue at the end of previous allocation only
if the previous allocation ended in the middle of the page.

These drivers should not be relying on CONFIG_USB_DEBUG.  By doing this,
it prevents users of kernels that do not enable this option from
enabling debugging in these drivers, unlike all other usb-serial
drivers.

ab1666c136 USB: quirk PLL power down mode
On some AMD 700 series southbridges, ISO OUT transfers (such as audio
playback through speakers) on the USB OHCI controller may be corrupted
when an A-Link express power saving feature is active.

PLL power down mode in conjunction with link power management feature
L1 being enabled is the bad combination ... this patch prevents them
from being enabled when ISO transfers are pending.

e5fbab51b4 usb: cdc-acm: drain writes on close
Add a mechanism to let the write queue drain naturally before
closing the TTY, rather than always losing that data.  There
is a timeout, so it can't wait too long.

Provide missing locking inside acm_wb_is_avail(); it matters
more now.  Note, this presumes an earlier patch was applied,
removing a call to this routine where the lock was held.

Slightly improved diagnostics on write URB completion, so we
can tell when a write URB gets killed and, if so, how much
data it wrote first ... and so that I/O path is normally
silent (and can't much change timings).

934da4635c usb: cdc-acm: stop dropping tx buffers
The "increase cdc-acm write throughput" patch left in place two
now-obsolete mechanisms, either of which can make the cdc-acm
driver drop TX data (nasty!).  This patch removes them:

  - The write_ready flag ... if an URB and buffer were found,
    they can (and should!) always be used.

  - TX path acm_wb_is_used() ... used when the buffer was just
    allocated, so that check is pointless.

Also fix a won't-yet-matter leak of a write buffer on a disconnect path.

  (b) remove the recently-added self-deadlock.

(The "fix disconnect bug in cdc-acm" patch was incomplete and incorrect.)

Plus a small "sparse" fix:  rename a local variable so it doesn't

1f1ba11b64 usb gadget: issue notifications from ACM function
Update the CDC-ACM gadget code to support the peripheral-to-host
notifications when the tty is opened or closed, or issues a BREAK.
The serial framework code calls new generic hooks; right now only
CDC-ACM uses those hooks.  This resolves several REVISIT comments
in the code.  (Based on a patch from Felipe Balbi.)

Note that this doesn't expose USB_CDC_CAP_BRK to the host, since
this code still rejects USB_CDC_REQ_SEND_BREAK control requests
for host-to-peripheral BREAK signaling (received via /dev/ttyGS*).

3f02a957d5 usb: ISP1760: improve pre-fetch timing
ISP1760 requires a delay of 90ns between programming the address and
reading the data.  Current driver solves this by a mdelay(1) which is
very heavy weighted and slow.  This patch applies the workaround from
the ISP1760 FAQ by using two different banks for PTD and payload data
and using a common wait for them.  This wait is done by an additional
ISP1760 access (whose timing constraints guarantee the 90ns delay).
This improves speed when reading from an USB stick from:

  $ time dd if=/dev/sda of=/dev/zero bs=65536 count=1638
  real    1m 15.43s
  user    0m 0.44s
  sys     0m 39.46s

to

  $ time dd if=/dev/sda of=/dev/zero bs=65536 count=1638
  real    0m 18.53s
  user    0m 0.16s
