reg_pages should always contain mr->npage since when the mr is finally
de-reg'd it is always subtracted out.
If there were any error exits then mlx5_ib_rereg_user_mr() would leave the
reg_pages adjusted and this will cause it to be double subtracted
eventually.
The manipulation of reg_pages is inherently connected to the umem, so lift
it out of set_mr_fields() and only adjust it around creating/destroying a
umem.
reg_pages is only used for diagnostics in sysfs.

be written to handle _all_ the possible variants of various sprintf family
uses in sysfs show functions.
While there, make the code more legible and update its style to be more

o Use intermediate pointers for dereferences
o Add and use string lookup functions
o return early when any intermediate call fails so normal return is
at the bottom of the function

number of possible connections that can be created. For those adapters,
it's preferred to reduce the max IO size to be able to create more

for enabling the option to control it for suitable adapters.

Pull timer fixes from Thomas Gleixner:
"A time namespace fix and a matching selftest. The futex absolute
timeouts which are based on CLOCK_MONOTONIC require time namespace
corrected. This was missed in the original time namesapce support"
* tag 'timers-urgent-2020-10-25' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
selftests/timens: Add a test for futex()
futex: Adjust absolute futex timeouts with per time namespace offset
- A trivial build fix for sched_feat() to compile correctly with
CONFIG_JUMP_LABEL=n
- Replace a zero lenght array with a flexible array.
