Maciej W. Rozycki db87313148 MIPS: asm/bitops.h: Guard CLZ with `.set mips32'
This fixes:

{standard input}: Assembler messages:
{standard input}:145: Error: opcode not supported on this processor: vr5000 (mips4) `clz $2,$2'
{standard input}:920: Error: opcode not supported on this processor: vr5000 (mips4) `clz $7,$9'

{standard input}:4329: Error: opcode not supported on this processor: vr5000 (mips4) `clz $2,$2'
make[2]: *** [arch/mips/mm/tlbex.o] Error 1

which triggered due to a regression causing the file to be built with
`-march=r5000' rather than `-march=sb1', fixed separately.  Nevertheless
the error should not happen, the other uses of CLZ are appropriately
guarded.  This change copies the arrangement from one of those other
places.

Maciej W. Rozycki bf4aac07b5 MIPS: c-r4k: Avoid duplicate CPU_74K/CPU_1074K checks
Code in a switch statement in probe_pcache checks the CPU type twice
unnecessarily for processor implementations that have the alias removal
feature reported by the CP0 Config7.AR and Config7.IAR bits.  This change
rewrites the affected fragment avoiding the extraneous check and improving
readability.

Jonas Gorski 86ee4333ba MIPS: BCM63xx: Replace irq dispatch code with a generic version
The generic version uses a variable length of u32 registers instead of u32/u64.
This allows easier support for "wider" registers without having to rewrite
everything.

This "generic" version is as fast as the old version in the best case
(i == next set bit), and twice as fast in the worst case in 64 bits.

Using a macro was chosen over a (forced) inline version because gcc generated
more compact code with the macro.

The change from (signed) int to unsigned int for i and to_call was intentional
as the value can be only between 0 and (width - 1) anyway, and allowed gcc to
optimise the code a bit further.

Manuel Lauss 474402291a MIPS: Alchemy: clock framework integration of onchip clocks
This patch introduces common clock framework integration for all
configurable on-chip clocks on Alchemy chips:

- 2 or 3 PLLs which generate integer multiples of the root rate 12MHz,
- 6 dividers which take one of the 3 PLLs as input and divide their
  rate by either multiples of 2 or 1 (Au1300).
- another bank of up to 6 muxes which take either one of the 6
  above dividers or one of the PLLs directly and divide their rate
  further by 1, 2, 3 or 4.
- a few other sources which are used by onchip peripherals and are
  informational.

This implementation will take the clock tree as it was set up
by boot firmware: all in-kernel boards should continue to work
without having to set up the clock tree in board code.

CLK_IGNORE_DISABLED will be removed once all drivers have been
converted.

(introduced in 3.15) that can end up triggering a file system
 corruption error after a journal replay.  (It shouldn't lead to any
 actual data corruption, but it is scary and can force file systems to
 be remounted read-only, etc.)

 "Summary:
  - Fix for a boot regression introduced in v3.16-rc1,
  - Fix for a build issue in -next"

Christoph Hellwig questioned why mach_random_get_entropy should be
exported to modules, and Geert explains that random_get_entropy() is
called by at least the crypto layer and ends up using it on m68k.  On
most other architectures it just uses get_cycles() (which is typically
inlined and doesn't need exporting),

Pull parisc fixes from Helge Deller:
 "The major patch in here is one which fixes the fanotify_mark() syscall
  in the compat layer of the 64bit parisc kernel.  It went unnoticed so
  long, because the calling syntax when using a 64bit parameter in a
  32bit syscall is quite complex and even worse, it may be even
  different if you call syscall() or the glibc wrapper.  This patch
  makes the kernel accept the calling convention when called by the
  glibc wrapper.

  The other two patches are trivial and remove unused headers, #includes
  and adds the serial ports of the fastest C8000 workstation to the
  parisc-kernel internal hardware database"

Add it to the clk init function. Not pretty, but the mess there is

Helge Deller ab8a261ba5 parisc: fix fanotify_mark() syscall on 32bit compat kernel
On parisc we can not use the existing compat implementation for fanotify_mark()
because for the 64bit mask parameter the higher and lower 32bits are ordered
differently than what the compat function expects from big endian
architectures.

Specifically:
It finally turned out, that on hppa we end up with different assignments
of parameters to kernel arguments depending on if we call the glibc
wrapper function
 int fanotify_mark (int __fanotify_fd, unsigned int __flags,
                    uint64_t __mask, int __dfd, const char *__pathname);
or directly calling the syscall manually
 syscall(__NR_fanotify_mark, ...)

Reason is, that the syscall() function is implemented as C-function and
because we now have the sysno as first parameter in front of the other
parameters the compiler will unexpectedly add an empty paramenter in
front of the u64 value to ensure the correct calling alignment for 64bit
values.
This means, on hppa you can't simply use syscall() to call the kernel
fanotify_mark() function directly, but you have to use the glibc
function instead.

This patch fixes the kernel in the hppa-arch specifc coding to adjust
the parameters in a way as if userspace calls the glibc wrapper function
fanotify_mark().
