Since the commit 50bed2e286 (sg: disable
interrupts inside sg_copy_buffer), no need to disable interrupts
before calling scsi_sg_copy_from_buffer. So we can simplify
tw_transfer_internal, which disables interrupts just for
scsi_sg_copy_from_buffer.

The current handling of NO_SENSE check condition is the same as
RECOVERED_ERROR, and assumes that in both cases, the I/O was fully
transferred.
We have seen cases of arrays returning with NO_SENSE (no error), but
the I/O was not completely transferred, thus residual set. Thus,
rather than return good_bytes as the entire transfer, set good_bytes
to 0, so that the midlayer then applies the residual in calculating
the transfer, and for sd, will fail the I/O and fall into a retry
path.

This patch implements q->lld_busy_fn() for scsi mid layer to export
its busy state for request stacking drivers.
For efficiency, no lock is taken to check the busy state of
shost/starget/sdev, since the returned value is not guaranteed and
may be changed after request stacking drivers call the function,
regardless of taking lock or not.
When scsi can't dispatch I/Os anymore and needs to kill I/Os
(e.g. !sdev), scsi needs to return 'not busy'.
Otherwise, request stacking drivers may hold requests forever.

commit e2a6b85247
net: Enable TSO if supported by at least one device
didn't do what was intended because the netdev_compute_features
function was designed for conjunctions. So what happened was that
it would simply take the TSO status of the last constituent device.
This patch extends it to support both conjunctions and disjunctions
under the new name of netdev_increment_features.
It also adds a new function netdev_fix_features which does the
sanity checking that usually occurs upon registration. This ensures
that the computation doesn't result in an illegal combination
since this checking is absent when the change is initiated via
ethtool.
The two users of netdev_compute_features have been converted.

In the above commit the "acpi.power_nocheck" module parameter is defined
in drivers/acpi/power.c file. As several module parameters using the same ACPI
prefix are defined in the different files(for example: power_nocheck is
defined in drivers/acpi/power.c,debug_layer/debug_level are defined in
drivers/acpi/debug.c) and there exists another module between them, the
warning message will be printed when using the current generic param code.
(In the function of param_sysfs_init).
In fact when ACPI is selected, the drivers/acpi/power will also be compiled
as built-in kernel.So this issue can be fixed by the following approach.
workaround it by adjusting the module link order in drivers/acpi/Makefile.
In such case the module parameter using the same prefix(ACPI) are put together
in the param data section.
Of course the better solution is to fix it in generic param code related
with sysfs.

To synchronize clip lists with the X server, the DRM lock must be held while
looking at drawable clip lists. To synchronize with other ring access, the
ring mutex must be held while inserting commands into the ring. Failure to
do the first resulted in easy visual corruption when moving windows, and the
second could have corrupted the ring with DRI2.
Grabbing the DRM lock involves using the DRM tasklet mechanism, grabbing the
ring mutex means potentially sleeping. Deal with both of these by always
running the tasklet from a work handler.
Also, protect from clip list changes since the vblank request was queued by
making sure the window has at least one rectangle while looking inside,
preventing oopses .

Fixes warning from exconfig.c on 64-bit build.

Examines the return object from a call to acpi_evaluate_object.
Any Index or RefOf references are automatically dereferenced in
an attempt to return something useful (these reference types
cannot be converted into an external ACPI_OBJECT.)

Return status from acpi_ut_init_globals. This is used by both
the kernel subsystem and the utilities such as iASL compiler.
The function could possibly fail when the caches are initialized.

Without this change, a table cannot be loaded again once it has
been loaded/unloaded one time. The current mechanism does not
unregister a table upon an unload. During a load, if the same
table is found, this no longer returns an exception.

Previously, dynamically loaded tables were simply mapped, but on some machines
this memory is corrupted after suspend. Now copy the table to a local buffer.
For OpRegion case, added checksum verify. Use the table length from the table header,
not the region length. For Buffer case, use the table length also.

Reset methods don't have access to phys link status for slave links
and may incorrectly indicate device presence causing unnecessary probe
failures for unoccupied links. This patch clears device class to NONE
during post-reset processing if phys link is offline.
As on/offlineness semantics is strictly defined and used in multiple
places by the core layer, this won't change behavior for drivers which
don't use slave links.

Slave link action mask is transferred to master link and all the EH
actions are taken by the master link. ata_eh_about_to_do() and
ata_eh_done() are called with ATA_EH_ALL_ACTIONS to clear the slave
link actions during transfer. This always sets ATA_PFLAG_RECOVERED
flag causing spurious "EH complete" messages.
Don't set ATA_PFLAG_RECOVERED for slave link actions.
