x86: add MAP_STACK mmap flag

as per this discussion:

   http://lkml.org/lkml/2008/8/12/423

Pardo reported that 64-bit threaded apps, if their stacks exceed the
combined size of ~4GB, slow down drastically in pthread_create() - because
glibc uses MAP_32BIT to allocate the stacks. The use of MAP_32BIT is
a legacy hack - to speed up context switching on certain early model
64-bit P4 CPUs.

So introduce a new flag to be used by glibc instead, to not constrain
64-bit apps like this.

glibc can switch to this new flag straight away - it will be ignored
by the kernel. If those old CPUs ever matter to anyone, support for
it can be implemented.

spi: bugfix spi_add_device() with duplicate chipselects

When reviewing a recent patch I noticed a potential trouble spot in the
registration of new SPI devices.  The SPI master driver is told to set
the device up before adding it to the driver model, so that it's always
properly set up when probe() is called.  (This is important, because in
the case of inverted chipselects, this device can make the bus misbehave
until it's properly deselected.  It's got to be set up even if no driver
binds to the device.)

The trouble spot is that it doesn't first verify that no other device
has been added using that chipselect.  If such a device has been added,
its configuration gets trashed.  (Fortunately this has not been a common
error!)

The fix here adds an explicit check, and a mutex to protect the relevant
critical region.

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.

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...

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.

Zhao Yakui [Mon, 11 Aug 2008 02:33:31 +0000 (10:33 +0800)]
ACPI: Avoid bogus EC timeout when EC is in Polling mode

When EC is in Polling mode, OS will check the EC status continually by using
the following source code:
       clear_bit(EC_FLAGS_WAIT_GPE, &ec->flags);
       while (time_before(jiffies, delay)) {
               if (acpi_ec_check_status(ec, event))
                    return 0;
               msleep(1);
       }
But msleep is realized by the function of schedule_timeout. At the same time
although one process is already waken up by some events, it won't be scheduled
immediately. So maybe there exists the following phenomena:
     a. The current jiffies is already after the predefined jiffies.
But before timeout happens, OS has no chance to check the EC
status again.
     b. If preemptible schedule is enabled, maybe preempt schedule will happen
before checking loop. When the process is resumed again, maybe
timeout already happens, which means that OS has no chance to check
the EC status.

In such case maybe EC status is already what OS expects when timeout happens.
But OS has no chance to check the EC status and regards it as AE_TIME.

So it will be more appropriate that OS will try to check the EC status again
when timeout happens. If the EC status is what we expect, it won't be regarded
as timeout. Only when the EC status is not what we expect, it will be regarded
as timeout, which means that EC controller can't give a response in time.

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

ISP1760 access (whose timing constraints guarantee the 90ns delay).

USB: serial gadget: rx path data loss fixes

Update RX path handling in new serial gadget code to cope better with
RX blockage:  queue every RX packet until its contents can safely be
passed up to the ldisc.  Most of the RX path work is now done in the
RX tasklet, instead of just the final "push to ldisc" step.  This
addresses some cases of data loss:

  - A longstanding serial gadget bug: when tty_insert_flip_string()
    didn't copy the entire buffer, the rest of the characters were
    dropped!  Now that packet stays queued until the rest of its data
    is pushed to the ldisc.

  - Another longstanding issue:  in the unlikely case that an RX
    transfer returns data and also reports a fault, that data is
    no longer discarded.

  - In the recently added RX throttling logic:  it needs to stop
    pushing data into the TTY layer, instead of just not submitting
    new USB read requests.  When the TTY is throttled long enough,
    backpressure will eventually make the OUT endpoint NAK.

Also: an #ifdef is removed (no longer necessary); and start switching
to a better convention for debug messages (prefix them with tty name).

or (b) a user-space application (e.g. udev) can switch it to modem mode.

This patch does allow for manual override by adding a usb-storage module
parameter 'swi_tru_install' which can force the modem into either mode
