Pull MIPS updates from Paul Burton:
 "Main MIPS changes:

   - boot_mem_map is removed, providing a nice cleanup made possible by
     the recent removal of bootmem.

   - Some fixes to atomics, in general providing compiler barriers for
     smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs
     or MIPS32 systems using cmpxchg64().

   - Conversion to the new generic VDSO infrastructure courtesy of
     Vincenzo Frascino.

   - Removal of undefined behavior in set_io_port_base(), fixing the
     behavior of some MIPS kernel configurations when built with recent
     clang versions.

   - Initial MIPS32 huge page support, functional on at least Ingenic
     SoCs.

   - pte_special() is now supported for some configurations, allowing
     among other things generic fast GUP to be used.

   - Miscellaneous fixes & cleanups.

  And platform specific changes:

   - Major improvements to Ingenic SoC support from Paul Cercueil,
     mostly enabled by the inclusion of the new TCU (timer-counter unit)
     drivers he's spent a very patient year or so working on. Plus some
     fixes for X1000 SoCs from Zhou Yanjie.

   - Netgear R6200 v1 systems are now supported by the bcm47xx platform.

   - DT updates for BMIPS, Lantiq & Microsemi Ocelot systems"

kbuild: add $(BASH) to run scripts with bash-extension

2019-09-04T13:54:13+00:00

CONFIG_SHELL falls back to sh when bash is not installed on the system,
but nobody is testing such a case since bash is usually installed.
So, shell scripts invoked by CONFIG_SHELL are only tested with bash.

It makes it difficult to test whether the hashbang #!/bin/sh is real.
For example, #!/bin/sh in arch/powerpc/kernel/prom_init_check.sh is
false. (I fixed it up)

Besides, some shell scripts invoked by CONFIG_SHELL use bash-extension
and #!/bin/bash is specified as the hashbang, while CONFIG_SHELL may
not always be set to bash.

Probably, the right thing to do is to introduce BASH, which is bash by
default, and always set CONFIG_SHELL to sh. Replace $(CONFIG_SHELL)
with $(BASH) for bash scripts.

If somebody tries to add bash-extension to a #!/bin/sh script, it will
be caught in testing because /bin/sh is a symlink to dash on some major
distributions.

This patch adds a description of the PTP ready interrupt, which can be
triggered when a PTP timestamp is available on an hardware FIFO.
