nfsd4: support minorversion 1 by default

We now have minimal minorversion 1 support; turn it on by default.

This can still be turned off with "echo -4.1 >/proc/fs/nfsd/versions".

Rename functions in include/net/ll_poll.h to busy wait.
Clarify documentation about expected power use increase.
Rename POLL_LL to POLL_BUSY_LOOP.
Add need_resched() testing to poll/select busy loops.

Note, that in select and poll can_busy_poll is dynamic and is

[SCSI] mpt3sas: fix for kernel panic when driver loads with HBA conected to non LUN 0 configured expander

With some enclosures when LUN 0 is not created but LUN 1 or LUN X is created
then SCSI scan procedure calls target_alloc, slave_alloc call back functions
for LUN 0 and slave_destory() for same LUN 0.

In these kind of cases within slave_destroy, pointer to scsi_target in
_sas_device structure is set to NULL, following which when slave_alloc for LUN
1 is called then starget would not be set properly for this LUN.  So,
scsi_target pointer pointing to NULL value would lead to a crash later in the
discovery procedure.

To solve this issue set the sas_device's scsi_target pointer to scsi_device's
scsi_target if it is NULL earlier in slave_alloc callback function.

[SCSI] mpt3sas: Infinite loops can occur if MPI2_IOCSTATUS_CONFIG_INVALID_PAGE is not returned

Infinite loop can occur if IOCStatus is not equal to
MPI2_IOCSTATUS_CONFIG_INVALID_PAGE value in the while loops in functions
_scsih_search_responding_sas_devices,
_scsih_search_responding_raid_devices and
_scsih_search_responding_expanders

So, Instead of checking for MPI2_IOCSTATUS_CONFIG_INVALID_PAGE value,
in this patch code is modified to check for IOCStatus not equals to
MPI2_IOCSTATUS_SUCCESS to break the while loop.

   that the IOC detected a partial memory failure.
2. Added ElapsedSeconds field to RAID Volume Indicator Structure. Added
   Elapsed Seconds Valid flag to Flags field of this structure.
3. Added ElapsedSeconds field to Integrated RAID Operations Status Event Data.
4. Added two new AbortType values for TargetModeAbort Request, one to abort
   all I/Os from a single initiator, and the other to abort only Command IUs.
5. Added a new chapter covering DMA Flags and Multicast Modes.
6. In the IOCSettings field of BIOS Page 1, modified the Adapter Support bits
   description to specify X86 BIOS.
7. Marked bit 0 of the ControlFlags field of SAS IO Unit Page 1 as
   obsolete. This was the Clear SATA Affiliation flag.
8. Added additional requirements for certain IOCs that support more than eight

[SCSI] mpt3sas: when async scanning is enabled then while scanning, devices are removed but their transport layer entries are not removed

When Async scanning mode is enabled and device scanning is in progress,
devices should not be removed. But in actuality, devices are removed but
their transport layer entries are not removed. This causes error to add
the same device to the transport layer after host reset or diagnostic
reset.

So, in this patch, modified the code in such a way that device is not removed
when Async scanning mode is enabled and device scanning is in progress.
