MIPS: Loongson 2: Sort out clock managment.

2012-08-01T16:10:06+00:00

For unexplainable reasons the Loongson 2 clock API was implemented in a
module so fixing this involved shifting large amounts of code around.

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

Pull MIPS updates from Ralf Baechle:
 "More hardware support across the field including a bunch of device
  drivers.  The highlight however really are further steps towards
  device tree.

  This has been sitting in -next for ages.  All MIPS _defconfigs have
  been tested to boot or where I don't have hardware available, to at
  least build fine."

posix_types.h: Cleanup stale __NFDBITS and related definitions

2012-07-26T20:36:43+00:00

Recently, glibc made a change to suppress sign-conversion warnings in
FD_SET (glibc commit ceb9e56b3d1).  This uncovered an issue with the
kernel's definition of __NFDBITS if applications #include
 after including .  A build failure would
be seen when passing the -Werror=sign-compare and -D_FORTIFY_SOURCE=2
flags to gcc.

It was suggested that the kernel should either match the glibc
definition of __NFDBITS or remove that entirely.  The current in-kernel
uses of __NFDBITS can be replaced with BITS_PER_LONG, and there are no
uses of the related __FDELT and __FDMASK defines.  Given that, we'll
continue the cleanup that was started with commit 8b3d1cda4f5f
("posix_types: Remove fd_set macros") and drop the remaining unused
macros.

Additionally, linux/time.h has similar macros defined that expand to
nothing so we'll remove those at the same time.

MIPS: Add CPU support for Loongson1B

2012-07-23T12:57:04+00:00

Loongson 1B is a 32-bit SoC designed by Institute of Computing Technology
(ICT) and the Chinese Academy of Sciences (CAS), which implements the
MIPS32 release 2 instruction set.

[ralf@linux-mips.org: But which is not strictly a MIPS32 compliant device
which also is why it identifies itself with the Legacy Vendor ID in the
PrID register.  When applying the patch I shoveled some code around to
keep things in alphabetical order and avoid forward declarations.]

MIPS: Prune some target specific code out of prom.c

2012-07-23T12:54:52+00:00

This code is not common enough to be in a shared file.  It is also not
used by any existing boards, so just remove it.

[ralf@linux-mips.org: Dropped removal of irq_create_of_mapping which was
already removed by abd2363f6a5f1030b935e0bdc15cf917313b3b10
[irq_domain/mips: Allow irq_domain on MIPS].  Moved device_tree_init() and

MIPS: call set_cpu_online() on cpu being brought up with irq disabled

2012-07-19T09:23:44+00:00

To prevent a problem as commit 5fbd036b [sched: Cleanup cpu_active madness]
and commit 2baab4e9 [sched: Fix select_fallback_rq() vs cpu_active/cpu_online]
try to resolve, move set_cpu_online() to the brought up CPU and with irq
disabled.
