[PARISC] Make ioremap default to _nocache

2006-04-21T22:20:35+00:00

Since it is way more work to change most drivers to comply with parisc, take
the easy way out and make ioremap _NO_CACHE by default. This is in line with
what powerpc does.

[PARISC] Add new entries to the syscall table

2006-04-21T22:20:35+00:00

Most are easy, but sync_file_range needed special handling when entering
through the 32-bit syscall table.

[PARISC] Further work for multiple page sizes

2006-04-21T22:20:34+00:00

More work towards supporing multiple page sizes on 64-bit. Convert
some assumptions that 64bit uses 3 level page tables into testing
PT_NLEVELS. Also some BUG() to BUG_ON() conversions and some cleanups
to assembler.

[PATCH] Configurable NODES_SHIFT

2006-04-11T13:18:39+00:00

Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for
each arch.  Its definition is sometimes configurable.  Indeed, ia64 defines 5
NODES_SHIFT values in the current git tree.  But it looks a bit messy.

SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has
been changeable by config.  Suitable node's number may be changed in the
future even if it is other architecture.  So, I wrote configurable node's
number.

This patch set defines just default value for each arch which needs multi
nodes except ia64.  But, it is easy to change to configurable if necessary.

On ia64 the number of nodes can be already configured in generic ia64 and SN2
config.  But, NODES_SHIFT is defined for DIG64 and HP'S machine too.  So, I
changed it so that all platforms can be configured via CONFIG_NODES_SHIFT.  It
would be simpler.

[PARISC] Make local_t use atomic_long_t

2006-03-30T17:48:56+00:00

As done in asm-generic/local.h in mainline. Otherwise local_t was 32-bit
even on a 64-bit kernel.

[PARISC] Remove obsolete CONFIG_DEBUG_IOREMAP

2006-03-30T17:48:50+00:00

Remove CONFIG_DEBUG_IOREMAP, it's now obsolete and won't work anyway.
Remove it from lib/KConfig since it was only available on parisc.
