Instead of creating our own kthread (dlm_astd) to deliver
callbacks for all lockspaces, use a per-lockspace workqueue
to deliver the callbacks. This eliminates complications and
slowdowns from many lockspaces sharing the same thread.

By pre-allocating rsb structs before searching the hash
table, they can be inserted immediately. This avoids
always having to repeat the search when adding the struct
to hash list.
This also adds space to the rsb struct for a max resource
name, so an rsb allocation can be used by any request.
The constant size also allows us to finally use a slab
for the rsb structs.

In fs/dlm/lock.c in the dlm_scan_waiters() function there are 3 small
issues:
1) There's no need to test the return value of the allocation and do a
memset if is succeedes. Just use kzalloc() to obtain zeroed memory.
2) Since kfree() handles NULL pointers gracefully, the test of
'warned' against NULL before the kfree() after the loop is completely
pointless. Remove it.
3) The arguments to kmalloc() (now kzalloc()) were swapped. Thanks to
Dr. David Alan Gilbert for pointing this out.

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."

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.
