The PCC driver now handles mapping and unmapping of shared memory
areas as part of pcc_mbox_{request,free}_channel(). Without these before,
this xgene-slimpro I2C driver did handling of those mappings like several
other PCC mailbox client drivers.
There were redundant operations, leading to unnecessary code. Maintaining
the consistency across these driver was harder due to scattered handling
of shmem.
Just use the mapped shmem and remove all redundant operations from this
driver.

Pull drm fixes from Dave Airlie:
"Weekly drm fixes, I'll be honest and say I think this is larger than
I'd prefer at this point, the main blow out point is that xe has two
larger fixes.
One is a fix for active context utilisation reporting, it's for a
reported regression and will end up in stable anyways, so I don't see
any point in holding it up.
The second is a fix for mixed cpu/gpu atomics, which are currently
broken, but are also not something your average desktop/laptop user is
going to hit in normal operation, and having them fixed now is better
than threading them through stable later.
Other than those, it's mostly the usual, a bunch of amdgpu randoms and
a few other minor fixes.

pNFS/flexfiles: Record the RPC errors in the I/O tracepoints
NFSv4/pnfs: Layoutreturn on close must handle fatal networking errors
NFSv4: Handle fatal ENETDOWN and ENETUNREACH errors
The Linux client assumes that all filehandles are non-volatile for
renames within the same directory (otherwise sillyrename cannot work).
However, the existence of the Linux 'subtree_check' export option has
meant that nfs_rename() has always assumed it needs to flush writes
before attempting to rename.
Since NFSv4 does allow the client to query whether or not the server
exhibits this behaviour, and since knfsd does actually set the
appropriate flag when 'subtree_check' is enabled on an export, it
should be OK to optimise away the write flushing behaviour in the cases
where it is clearly not needed.
