Fix issues with the NeoMagic framebuffer driver.
It nicely complements my previous fix already in linus' tree. The only
thing missing now is that the external CRT will not be activated at neofb
init when external-only is selected, either by register read or
module/kernel parameter.
Testing was done on a Dell Latitude CPi-A/NM2200 chip.
Previous behaviour:
- before booting linux, set the preferred display config X via FN+F8
- boot linux, neofb stores the register values in a private
variable
- change the display config to Y via keystroke
- leave the machine in peace until display is blanked
- touching any key will result in display config X being restored
- booting up, the BIOS will acknowledge config Y, though...
Current behaviour:
At the time of unblanking, config Y is honoured because we now read back
register contents instead of just overwriting them with outdated values.

The changes in the tty related code introduced wrong parenthesis in a if

When the _CRS for a single HPET contains multiple EXTENDED_IRQ resources,
we overwrote hdp->hd_nirqs every time we found one.
So the driver worked when all the IRQs were described in a single
EXTENDED_IRQ resource, but failed when multiple resources were used.
(Strictly speaking, I think the latter is actually more correct, but both
styles have been used.)
Someday we should remove all the ACPI stuff from hpet.c and use PNP driver
registration instead. But currently PNP_MAX_IRQ is 2, and HPETs often have
more IRQs. Hint, hint, Adam :-)

Fix hole where tty structure can be released when reference count is non
zero. Existing code can sleep without tty_sem protection between deciding
to release the tty structure (setting local variables tty_closing and
otty_closing) and setting TTY_CLOSING to prevent further opens. An open
can occur during this interval causing release_dev() to free the tty
structure while it is still referenced.
This should fix bugzilla.kernel.org [Bug 6041] New: Unable to handle kernel
paging request
In Bug 6041, tty_open() oopes on accessing the tty structure it has
successfully claimed. Bug was on SMP machine with the same tty being
opened and closed by multiple processes, and DEBUG_PAGEALLOC enabled.

There's a bug in releasing scsi_device where the release function
actually frees the block queue. However, the block queue release
calls flush_work(), which requires process context (the scsi_device
structure may release from irq context). Update the release function
to invoke via the execute_in_process_context() API.
Also clean up the scsi_target structure releasing via this API.

We have several points in the SCSI stack (primarily for our device
functions) where we need to guarantee process context, but (given the
place where the last reference was released) we cannot guarantee this.
This API gets around the issue by executing the function directly if
the caller has process context, but scheduling a workqueue to execute
in process context if the caller doesn't have it. Unfortunately, it
requires memory allocation in interrupt context, but it's better than
what we have previously. The true solution will require a bit of
re-engineering, so isn't appropriate for 2.6.16.

If a low level driver wants to control max_sectors, it had to adjust
ap->host->max_sectors and set ATA_DFLAG_LOCK_SECTORS to tell
ata_scsi_slave_config not to override the limit. This is not only
cumbersome but also incorrect for hosts which support more than one
devices per port.
This patch adds per-device ->max_sectors. If the field is unset
(zero), libata core layer will adjust ->max_sectors according to
default rules. If the field is set, libata honors the setting.
