Lennert Buytenhek bd115ea007 [ARM] 3378/1: ixp2000: fix gpio interrupt handling
Patch from Lennert Buytenhek

ixp2000 used to initially mark GPIO interrupts as invalid, and not
mark them valid until set_irq_type() was called, but this doesn't
work if you want to use request_irq() with the SA_TRIGGER_* flags.

So, just mark the GPIO interrupts valid from the beginning.  We
configure GPIOs as inputs when set_irq_type() is called anyway, so
this shouldn't be a problem.

  [SPARC64]: Add a secondary TSB for hugepage mappings.
  [SPARC]: Respect vm_page_prot in io_remap_page_range().
2006-03-22 10:56:57 -08:00
David Gibson 42b88befd6 [PATCH] hugepage: is_aligned_hugepage_range() cleanup
Quite a long time back, prepare_hugepage_range() replaced
is_aligned_hugepage_range() as the callback from mm/mmap.c to arch code to
verify if an address range is suitable for a hugepage mapping.
is_aligned_hugepage_range() stuck around, but only to implement
prepare_hugepage_range() on archs which didn't implement their own.

Most archs (everything except ia64 and powerpc) used the same
implementation of is_aligned_hugepage_range().  On powerpc, which
implements its own prepare_hugepage_range(), the custom version was never
used.

In addition, "is_aligned_hugepage_range()" was a bad name, because it
suggests it returns true iff the given range is a good hugepage range,
whereas in fact it returns 0-or-error (so the sense is reversed).

This patch cleans up by abolishing is_aligned_hugepage_range().  Instead
prepare_hugepage_range() is defined directly.  Most archs use the default
version, which simply checks the given region is aligned to the size of a
hugepage.  ia64 and powerpc define custom versions.  The ia64 one simply
checks that the range is in the correct address space region in addition to
being suitably aligned.  The powerpc version (just as previously) checks
for suitable addresses, and if necessary performs low-level MMU frobbing to
set up new areas for use by hugepages.

No libhugetlbfs testsuite regressions on ppc64 (POWER5 LPAR).

Michael Buesch a7290ee08e [PATCH] Uninline sys_mmap common code (reduce binary size)
Remove the inlining of the new vs old mmap system call common code.  This
reduces the size of the resulting vmlinux for defconfig as follows:

mb@pc1:~/develop/git/linux-2.6$ size vmlinux.mmap*
   text    data     bss     dec     hex filename
3303749  521524  186564 4011837  3d373d vmlinux.mmapinline
3303557  521524  186564 4011645  3d367d vmlinux.mmapnoinline

The new sys_mmap2() has also one function call overhead removed, now.
(probably it was already optimized to a jmp before, but anyway...)

Andrew Morton 78eef01b0f [PATCH] on_each_cpu(): disable local interrupts
When on_each_cpu() runs the callback on other CPUs, it runs with local
interrupts disabled.  So we should run the function with local interrupts
disabled on this CPU, too.

And do the same for UP, so the callback is run in the same environment on both
UP and SMP.  (strictly it should do preempt_disable() too, but I think
local_irq_disable is sufficiently equivalent).

Also uninlines on_each_cpu().  softirq.c was the most appropriate file I could
find, but it doesn't seem to justify creating a new file.

Oh, and fix up that comment over (under?) x86's smp_call_function().  It
drives me nuts.

Michael Ellerman caf80e579b [PATCH] powerpc: Unconfuse htab_bolt_mapping() callers
htab_bolt_mapping() takes a vstart and pstart parameter, but all but one of
its callers actually pass it vstart and vstart. Luckily before it passes
paddr (calculated from paddr) to the hpte_insert routines it calls
virt_to_abs() (aka. __pa()) on the address, so there isn't actually a bug.

map_io_page() however does pass pstart properly, so currently it's broken
AFAICT because we're calling __pa(paddr) which will get us something very
large. Presumably no one's calling map_io_page() in the right context.

Anyway, change htab_bolt_mapping() callers to properly pass pstart, and then
use it properly in htab_bolt_mapping(), ie. don't call __pa() on it again.

Booted on p5 LPAR, iSeries and Power3.

The powerpc numa code unconditionally onlines all nodes from 0 to the
highest node id found, regardless of whether cpus or memory are
present in the nodes.  This wastes 8K per node and complicates some

doesn't map to one of the nodes discovered at boot.

Set nodes online as resources are scanned.  Fall back to node 0 only
when we're sure this isn't a NUMA machine.

Instead of defaulting to node 0 for cases of hot-adding a resource
which doesn't belong to any initialized node, assign it to the first
