[SPARC64]: Mark __ex_table section correctly.

2006-03-05T07:23:56+00:00

We must use the "a" (allocate) attribute every time we
emit an entry into the __ex_table section.

For consistency, use "a" instead of #alloc which is some
Solaris compat cruft GNU as provides on Sparc.

[SPARC64]: Make cpu_present_map available earlier.

2006-02-27T03:36:00+00:00

The change to kernel/sched.c's init code to use for_each_cpu()
requires that the cpu_possible_map be setup much earlier.

Set it up via setup_arch(), constrained to NR_CPUS, and later
constrain it to max_cpus in smp_prepare_cpus().

This fixes SMP booting on sparc64.

[PATCH] add asm-generic/mman.h

2006-02-15T23:32:22+00:00

Make new MADV_REMOVE, MADV_DONTFORK, MADV_DOFORK consistent across all
arches.  The idea is to make it possible to use them portably even before
distros include them in libc headers.

Move common flags to asm-generic/mman.h

[PATCH] madvise MADV_DONTFORK/MADV_DOFORK

2006-02-15T00:09:34+00:00

Currently, copy-on-write may change the physical address of a page even if the
user requested that the page is pinned in memory (either by mlock or by
get_user_pages).  This happens if the process forks meanwhile, and the parent
writes to that page.  As a result, the page is orphaned: in case of
get_user_pages, the application will never see any data hardware DMA's into
this page after the COW.  In case of mlock'd memory, the parent is not getting
the realtime/security benefits of mlock.

In particular, this affects the Infiniband modules which do DMA from and into
user pages all the time.

This patch adds madvise options to control whether memory range is inherited
across fork.  Useful e.g.  for when hardware is doing DMA from/into these
pages.  Could also be useful to an application wanting to speed up its forks
by cutting large areas out of consideration.

[SPARC]: Wire up sys_unshare().

2006-02-08T02:11:24+00:00

Also, the Solaris syscall table is sized differrently,
and does not go beyond entry 255, so trim off the excess
entries.

[SPARC64]: Implement __raw_read_trylock()

2006-01-24T05:03:56+00:00

generic__raw_read_trylock() just does a raw_read_lock() so that
isn't very useful.

[SPARC]: Add support for *at(), ppoll, and pselect syscalls.

2006-01-19T10:42:49+00:00

This also includes by necessity _TIF_RESTORE_SIGMASK support,
which actually resulted in a lot of cleanups.

The sparc signal handling code is quite a mess and I should
clean it up some day.

[SPARC64]: Serial Console for E250 Patch

2006-01-18T22:54:31+00:00

From: Eddie C. Dost 

I have the following patch for serial console over the RSC
(remote system controller) on my E250 machine. It basically adds
support for input-device=rsc and output-device=rsc from OBP, and
allows 115200,8,n,1,- serial mode setting.
