Lots of register access in these functions, some of which requires the
struct mutex.
These functions now hold the struct mutex across the calls to
i915_save_display and i915_restore_display, and so the internal mutex
calls in those functions have been removed. To ensure that no-one else
was calling them (and hence violating the new required locking
invarient), those functions have been made static.
gen6_enable_rps locks the struct mutex, and so i915_restore_state
unlocks the mutex around calls to that function.

It's not so much an error as a warning about normal Marvell crazines.
So don't use KERN_ERR that ends up spamming the console even in quiet
mode, it's not _that_ critical.
Explained by Jeff:
"Long explanation, it's a mess:
Marvell took standard AHCI, and bastardized it to include a weird mode
whereby PATA devices appear inside the AHCI DMA and interrupt
infrastructure you're familiar with.
So, PATA devices appear via pata_marvell driver, using basic legacy
IDE programming interface. But SATA devices, which might also be
attached to this chip, either work in under-performing mode or
simply don't work at all (e.g. newer 6 Gbps devices or port
multiplier attachments, NCQ, ...)
On the other hand, 'ahci' driver loads and works with the chip's
attached SATA devices quite beautifully, but is completely unable to
drive any attached PATA devices, due to the Marvell-specific
PATA-under-AHCI interface.
The "masking port_map 0x7 -> 0x3" message is the ahci driver "hiding"
the PATA port(s) from itself, making sure it will only drive the SATA
ports it knows how to drive."

This memcpy:
memcpy(cmd->sense_buffer, ei->SenseInfo,
ei->SenseLen > SCSI_SENSE_BUFFERSIZE ?
SCSI_SENSE_BUFFERSIZE :
ei->SenseLen);
The ei->SenseLen field is filled in by the Smart Array. For requests to
logical drives, it will not exceed 32 bytes, so should be ok, but for physical
requests it depends on the target device, not the Smart Array. It's conceivable
that this could exceed the 32 byte size of ei->SenseInfo. In that case, the memcpy
would read past the end of ei->SenseInfo, copying data from the next command,
as if it were sense data, or, if it happened to be the very last command in the
block of allocated commands, could fall off the end of the allocated area and
crash. I'm not aware of anyone ever encountering this behavior, but it could
conceivably happen. This bug was found by Coverity.

Avoid creating input routes with ip_route_me_harder.
It does not work for locally generated packets. Instead,
restrict sockets to provide valid saddr for output route (or
unicast saddr for transparent proxy). For other traffic
allow saddr to be unicast or local but if callers forget
to check saddr type use 0 for the output route.
The resulting handling should be:
- REJECT TCP:
- in INPUT we can provide addr_type = RTN_LOCAL but
better allow rejecting traffic delivered with
local route (no IP address => use RTN_UNSPEC to
allow also RTN_UNICAST).
- FORWARD: RTN_UNSPEC => allow RTN_LOCAL/RTN_UNICAST
saddr, add fix to ignore RTN_BROADCAST and RTN_MULTICAST
- OUTPUT: RTN_UNSPEC
- NAT, mangle, ip_queue, nf_ip_reroute: RTN_UNSPEC in LOCAL_OUT
- IPVS:
- use RTN_LOCAL in LOCAL_OUT and FORWARD after SNAT
to restrict saddr to be local

pca954x power-on default is channel 0 connected. If multiple pca954x
muxes are connected to the same physical I2C bus, the parent bus will
see channel 0 devices behind both muxes by default. This is bad.
Scenario:
-- pca954x @ 0x70 -- ch 0 (I2C-bus-101) -- EEPROM @ 0x50
|
I2C-bus-1 ---
|
-- pca954x @ 0x71 -- ch 0 (I2C-bus-111) -- EEPROM @ 0x50
1. Load I2C bus driver: creates I2C-bus-1
2. Load pca954x driver: creates virtual I2C-bus-101 and I2C-bus-111
3. Load eeprom driver
4. Try to read EEPROM @ 0x50 on I2C-bus-101. The transaction will also bleed
onto I2C-bus-111 because pca954x @ 0x71 channel 0 is connected by default.
Fix: Initialize pca954x to disconnected state in pca954x_probe()

The failure is as follows:
1. Userspace gets forcewake lock, lock count >=1
2. GPU hang/reset occurs (forcewake bit is reset)
3. count is now incorrect
The failure can only occur when using the forcewake userspace lock.
This has the unfortunate consequence of messing up the driver as well as
userspace, unless userspace closes the debugfs file, the kernel will
never end up waking the GT since the refcount will be > 1.
The solution is to try to recover the correct forcewake state based on
the refcount. There is a period of time where userspace reads/writes may
occur after the reset, before the GT has been forcewaked. The interface
was never designed to be a perfect solution for userspace reads/writes,
and the kernel portion is fixed by this patch.
