sparc,sparc64: unify kernel/

2008-12-04T17:17:21+00:00

o Move all files from sparc64/kernel/ to sparc/kernel
  - rename as appropriate
o Update sparc/Makefile to the changes
o Update sparc/kernel/Makefile to include the sparc64 files

NOTE: This commit changes link order on sparc64!

Link order had to change for either of sparc32 and sparc64.
And assuming sparc64 see more testing than sparc32 change link
order on sparc64 where issues will be caught faster.

sysdev: Pass the attribute to the low level sysdev show/store function

2008-07-22T04:55:02+00:00

This allow to dynamically generate attributes and share show/store
functions between attributes. Right now most attributes are generated
by special macros and lots of duplicated code. With the attribute
passed it's instead possible to attach some data to the attribute
and then use that in shared low level functions to do different things.

I need this for the dynamically generated bank attributes in the x86
machine check code, but it'll allow some further cleanups.

I converted all users in tree to the new show/store prototype. It's a single
huge patch to avoid unbisectable sections.

Runtime tested: x86-32, x86-64
Compiled only: ia64, powerpc
Not compile tested/only grep converted: sh, arm, avr32

[SPARC64]: Add NUMA support.

2008-04-24T06:32:17+00:00

Currently there is only code to parse NUMA attributes on
sun4v/niagara systems, but later on we will add such parsing
for older systems.

[SPARC64]: More sensible udelay implementation.

2007-07-16T11:05:02+00:00

Take a page from the powerpc folks and just calculate the
delay factor directly.

Since frequency scaling chips use a system-tick register,
the value is going to be the same system-wide.

[SPARC64]: Provide mmu statistics via sysfs.

2007-06-05T04:49:57+00:00

If the system supports hypervisor based statistics, allow them to
be fetched, enabled, and disabled via sysfs.

Enable and disable via the boolean:

/sys/devices/systems/cpu/cpuN/mmustat_enable

Statistic values are provided under:

/sys/devices/systems/cpu/cpuN/mmu_status/

[SPARC64]: Export basic cpu properties via sysfs.

Cache sizes, udelay_val, and clock_tick.

[SPARC64]: Move topology init code into new file, sysfs.c

2007-06-05T04:49:50+00:00

Also, use per-cpu data for struct cpu.  Calling kmalloc for
each cpu in topology_init() is just plain clumsy.
