The generic_defconfig is used for platforms like SEAD3 which do not
usually have fixed storage available, therefore NFS is the preferred
location of the RFS.
When the upstream kernel defconfig is built & tested on platforms such
as SEAD3 this leads to essentially false failures when the RFS fails to
mount.

There is little harm in having this feature enabled by default, so
enable it in the defconfig. Kernel autoconfiguration & DHCP must also be
selected to allow RFS on NFS.

It is pure mystery to me why we need to be on a specific CPU while
looking up a value in an array.
My best shot at this is that before commit d4019f0a ("cpufreq: move
freq change notifications to cpufreq core") it was required to invoke
cpufreq_notify_transition() on a special CPU.

Since it looks like a waste, remove it.

is redundant & needless. Remove it to simplify the code.

Correct the treatment of branching conditions for BC1EQZ and BC1NEZ
instructions in function isBranchInstr().

Previously, corresponding conditions were swapped, which in turn meant
that, for these two instructions, function isBranchInstr() returned
wrong value in its output parameter contpc.

This change is actually an extension of the fix done by the commit
93583e17 ("MIPS: math-emu: Fix BC1{EQ,NE}Z emulation"). That commit
dealt with a similar problem in function cop1Emulate(), while this
commit deals with condition handling in function isBranchInstr().
The code styles of changes in these two commits are kept as
consistent as possible.

Fix the problem of inaccurate identification of instructions BLEZL and
BGTZL in R2 emulation code by making sure all necessary encoding
specifications are met.

Previously, certain R6 instructions could be identified as BLEZL or
BGTZL. R2 emulation routine didn't take into account that both BLEZL
and BGTZL instructions require their rt field (bits 20 to 16 of
instruction encoding) to be 0, and that, at same time, if the value in
that field is not 0, the encoding may represent a legitimate MIPS R6
instruction.

This means that a problem could occur after emulation optimization,
when emulation routine tried to pipeline emulation, picked up a next
candidate, and subsequently misrecognized an R6 instruction as BLEZL
or BGTZL.

It should be said that for single pass strategy, the problem does not
happen because CPU doesn't trap on branch-compacts which share opcode
space with BLEZL/BGTZL (but have rt field != 0, of course).

Some users must have 4K pages while needing a 48-bit VA space size.
The cleanest way do do this is to go to a 4-level page table for this
case.  Each page table level using order-0 pages adds 9 bits to the
VA size (at 4K pages, so for four levels we get 9 * 4 + 12 == 48-bits.

For the 4K page size case only we add support functions for the PUD
level of the page table tree, also the TLB exception handlers get an
extra level of tree walk.

  fix several hangs that have happened in testing.

  This is obviously larger than I would have preferred at this point in
  time, but I don't think we can shave much off this and still get the
  desired results.

  In detail, this pull request contains:

   - a set of five fixes for NVMe, mostly from Christoph and one from
     Roland.

   - a series from Bart, fixing issues with dm-mq and SCSI shared tags
     and scheduling. Note that one of those patches commit messages may
     read like an optimization, but it is in fact an important fix for
     queue restarts in particular.

   - a series from Omar, most importantly fixing a hang with multiple
     hardware queues when we fail to get a driver tag. Another important
     fix in there is for resizing hardware queues, which nbd does when
     handling multiple sockets for one connection.
