The serio ports on i8042 are not completely isolated; while we provide
enough locking to ensure proper serialization when accessing control
and data registers AUX and KBD ports can still have an effect on each
other on PS/2 protocol level. The most prominent effect is that
issuing a command for the device connected to one port may cause
abort of the command currently executing by the device connected to
another port.
Since i8042 nor serio subsystem are not aware of the details of the
PS/2 protocol (length of the commands and their replies and so on) the
locking should be done on libps2 level by adding special handling when
we see that we are dealing with serio port on i8042.

->read_proc, ->write_proc are going away, ->proc_fops should be used instead.
The only tricky place is IDENTIFY handling: if for some reason
taskfile_lib_get_identify() fails, buffer _is_ changed and at least
first byte is overwritten. Emulate old behaviour with returning
that first byte to userspace and reporting length=1 despite overall -E.

* Allow ide_dev_read_id() helper to be called from the IRQ context by

* Switch ide_driveid_update() to set irq_ctx flag.
This change is needed for the consecutive patch which fixes races in
handling of user-space SET XFER commands but for improved bisectability
and clarity it is better to do it in a separate patch.

ide-tape used to hit
[ 58.614854] ide-tape: ht0: BUG: Two DSC requests queued!
due to the fact that another rq was being issued while the driver was
waiting for DSC to get set for the device executing ATAPI commands which
set the DSC to 1 to indicate completion.
Here's a sample output of that case:
issue REZERO_UNIT
[ 143.088505] ide-tape: ide_tape_issue_pc: retry #0, cmd: 0x01
[ 143.095122] ide: Enter ide_pc_intr - interrupt handler

[ 143.112601] ide-tape: idetape_postpone_request: cmd: 0x1, dsc_poll_freq: 2000
we stall the ide-tape queue here waiting for DSC
[ 143.119936] ide-tape: ide_tape_read_position: enter
[ 145.119019] ide-tape: idetape_do_request: sector: 4294967295, nr_sectors: 0
and issue the new READ_POSITION rq and hit the check.
[ 145.126247] ide-tape: ht0: BUG: Two DSC requests queued!
[ 145.131748] ide-tape: ide_tape_read_position: BOP - No
[ 145.137059] ide-tape: ide_tape_read_position: EOP - No
Also, ->postponed_rq used to point to that postponed request. To make
things worse, in certain circumstances the rq it was pointing to got
replaced unterneath it by swiftly reusing the same rq from the mempool
of the block layer practically confusing stuff even more.
However, we don't need to keep a pointer to that rq but simply wait for
DSC to be set first before issuing the follow-up request in the drive's
queue. In order to do that, we make idetape_do_request() first check the
DSC and if not set, we stall the drive queue giving the other device on
that IDE channel a chance.

That code uses dma_mapping_error() with a NULL device, which is
a bad idea :-) The proper fix might be to start using some kind
of pseudo device for all these low level mappings with the
hypervisor but that will be for another day. Since it directly
calls into the low level iommu code, I see no problem in having
it directly test against DMA_ERROR_CODE instead of using the
accessors with a NULL argument for now.

Michael Ellerman reported stack-frame size warnings being produced
for power_check_constraints(), which uses an 8*8 array of u64 and
two 8*8 arrays of unsigned long, which are currently allocated on the
stack, along with some other smaller variables. These arrays come
to 1.5kB on 64-bit or 1kB on 32-bit, which is a bit too much for the
stack.
This fixes the problem by putting these arrays in the existing
per-cpu cpu_hw_counters struct. This is OK because two of the call
sites have interrupts disabled already; for the third call site we
use get_cpu_var, which disables preemption, so we know we won't
get a context switch while we're in power_check_constraints().
Note that power_check_constraints() can be called during context
switch but is not called from interrupts.

Currently there is a bug where if you use oprofile on a pSeries
machine, then use perf_counters, then use oprofile again, oprofile
will not work correctly; it will lose the PMU configuration the next
time the hypervisor does a partition context switch, and thereafter
won't count anything.
Maynard Johnson identified the sequence causing the problem:
- oprofile setup calls ppc_enable_pmcs(), which calls
pseries_lpar_enable_pmcs, which tells the hypervisor that we want
to use the PMU, and sets the "PMU in use" flag in the lppaca.
This flag tells the hypervisor whether it needs to save and restore
the PMU config.
- The perf_counter code sets and clears the "PMU in use" flag directly
as it context-switches the PMU between tasks, and leaves it clear
when it finishes.
- oprofile setup, called for a new oprofile run, calls ppc_enable_pmcs,
which does nothing because it has already been called. In particular
it doesn't set the "PMU in use" flag.
This fixes the problem by arranging for ppc_enable_pmcs to always set
the "PMU in use" flag. It makes the perf_counter code call
ppc_enable_pmcs also rather than calling the lower-level function
directly, and removes the setting of the "PMU in use" flag from
pseries_lpar_enable_pmcs, since that is now done in its caller.
This also removes the declaration of pasemi_enable_pmcs because it
isn't defined anywhere.

A misconfiguration by the firmware of the U4 PCIe bridge on PowerMac G5
with the U4 bridge (latest generations, may also affect the iMac G5
"iSight") is causing us to re-assign the PCI BARs of the video card,
which can get it out of sync with the firmware, thus breaking offb.
This works around it by fixing up the bridge configuration properly
at boot time. It also fixes a bug where the firmware provides us with
an incorrect set of accessible regions in the device-tree.

Switch to using the Power ISA defined PTE format when we have a 64-bit
PTE. This makes the code handling between fsl-booke and book3e-64
similiar for TLB faults.
Additionally this lets use take advantage of the page size encodings and
full permissions that the HW PTE defines.
Also defined _PMD_PRESENT, _PMD_PRESENT_MASK, and _PMD_BAD since the
32-bit ppc arch code expects them.

The SLB can change sizes across a live migration, which was not
being handled, resulting in possible machine crashes during
migration if migrating to a machine which has a smaller max SLB
size than the source machine. Fix this by first reducing the
SLB size to the minimum possible value, which is 32, prior to
migration. Then during the device tree update which occurs after
migration, we make the call to ensure the SLB gets updated. Also
add the slb_size to the lparcfg output so that the migration
tools can check to make sure the kernel has this capability
before allowing migration in scenarios where the SLB size will change.

On certain PowerMacs, a module (therm_windtunnel) controls various
thermal settings (it can report CPU/case temperature, change speed
of internal fans, etc.)
By default, the hardware thermal control has a temperature limit to
protect the computer from damages (the default limit seems to be 80°C)
but therm_windtunnel.c reduces it to an anormaly low value (65°C),
which means that he computer will shut down randomly when hit by direct
sun light or during summer (summer in France can be quite hot), actually
possibly losing data instead of protecting it.
The overheat limit in therm_windtunnel.c:253-254 should be set to 75°C
and 70°C instead of 65°C and 60°C respectively.

The two versions are doing almost exactly the same thing. No need to
maintain them as separate files. This patch also has the side effect
of making the PCI device tree scanning code available to 32 bit powerpc
machines, but no board ports actually make use of this feature at this
point.

For cuImage format it's necessary to provide clock fixups since u-boot will
not pass necessary clock frequency into the dtb included into cuImage so we
implement the clock fixups as defined in the technical documentation for the
board and update header file with the basic register definitions.

This patch adds support for the ESTeem 195E Hotfoot SBC.
There are several variants of the SBC deployed, single/dual
ethernet+serial, and also 4MB/8MB flash variations. In the interest of
having a single kernel image boot on all boards, the cuboot shim detects
the differences and mangles the DTS tree appropriately.
With the exception of the CF interface that was never populated on
production boards, this code/DTS supports all boardpop options.

This moves the code to start the decrementer on 40x and BookE into
a separate function which is now called from time_init() and
secondary_time_init(), before the respective clock sources are
registered. We also remove the 85xx specific code for doing it
from the platform code.
