We used single shared fbops struct and patched it at fb init time with
pointers to the right variant. On mixed multicard, this meant that
it was either sending NV50-style commands to all cards, or NV04-style
commands to all cards.

nouveau_gem_ioctl_cpu_prep calls ttm_bo_wait without the bo lock held.
ttm_bo_wait unlocks that lock, and so must be called with it held.
Currently this bug causes libdrm nouveau_bo_busy() to hang the machine.

Apparently, they generate a PFIFO interrupt each time one of the
semaphore methods is executed if its ctxdma wasn't manually marked as
valid. This patch makes it flip the valid bit in response to the
DMA_SEMAPHORE method (which triggers the IRQ even for a valid ctxdma).

Due to a thinko, these were previously forced to VRAM even if we allocated
them in GART.
This commit fixes that bug, but keeps the previous behaviour of using VRAM
by default until it's been tested properly across more chipsets.

Discovery relates changes:
- Separated VPI_REGISTERED state of physical port into VFI_REGISTERED and
VPI_REGISTERED state so that driver can unregister physical port VPI
independent of VFI.
- Add code to unregister, re-init and re-register physical port VPI
when physical port NportID change.
- Add code to unregister and re-register VPI of a vport when its Nport
ID change.
- Add code in FDISC completion path to re-start FLOGI discovery when
a FDISC complete with LOGIN_REQUIRED reason code.
- Fix a memory leak in lpfc_init_vpi_cmpl
- Add code to start a timer for vport to retry FDISC when CVL is received
by a vport or physical port. If all Nports receive CVLs, then all timers
are cancelled and a logical link level discovery will be started after
one second.
- Flush ELS commands after killing all delayed ELS commands.

Added new callbacks phy_enable and set_phy_speed in the
mpt2sas_transport_functions template. This will allow end user to
enable/disable phys and change links rates using the SysFS interface.
Current implementation only supports direct attached phys, but we
could in the future add support for expander based phys.
A new subroutine mpt2sas_config_set_sas_iounit_pg1 was added;
this wrapper function used to send request to controller firmware to modify
the phys and link rates. A new subroutine _transport_find_local_phy was added;
a function for easly obtaining the local phy object for direct attached.
Example to disable a phy
echo 0 > /sys/class/phy3:0/enable
Example to enable the same phy
echo 1 > /sys/class/phy3:0/enable
Example to change the link rate to 1.5
#echo "1.5 Gbit" > /sys/class/phy3:0/maximum_linkrate
#cat /sys/class/phy3:0/negotiated_linkrate
1.5 Gbit
Example to change the link rate to 3.0
#echo "3.0 Gbit" > /sys/class/phy3:0/maximum_linkrate
#cat /sys/class/phy3:0/negotiated_linkrate
3.0 Gbit
Example to change the link rate to 6.0
#echo "6.0 Gbit" > /sys/class/phy3:0/maximum_linkrate
#cat /sys/class/phy3:0/negotiated_linkrate

On ppc64, an 32bit application was failing due to data buffers not being
copied properly from user to kernel memory. The problem due to improper
conversion of 32 to 64 bit pointers. The fix is to use compat_ptr to
setup the pointer compatibility in the routine _ctl_compat_mpt_command.

Use resource_size_t to define the type resource for the system interface
register set.
The existing implementation was using "unsigned long" which would be 32 bit
in 32 bit OS. If 32 bit OS is using 64 bit physical
address space for the system interface register set, we need to shift to
using resource_size_t which takes care of physical address space.

The driver hangs when doing `rmmod mpt2sas` if there are any
IR volumes present.The hang is due the scsi midlayer trying to access the
IR volumes after the driver releases controller resources. Perhaps when
scsi_remove_host is called,the scsi mid layer is sending some request.
This doesn't occur for bare drives becuase the driver is already reporting
those drives deleted prior to calling mpt2sas_base_detach.
To solve this issue, we need to delete the volumes as well.
