add uatomic_generic.h, use it for common definitions
uatomic_generic.h can be included by uatomic_arch_*.h to provide useful
default definitions. uatomic_arch_*.h can define whatever builtins
it wants to override, then uatomic_generic.h will provide what is not
already defined, as follows:
- uatomic_cmpxchg will use __sync_val_compare_and_swap builtins;
- uatomic_add_return will use __sync_fetch_and_add if uatomic_arch_*.h
did not provide a definition of uatomic_cmpxchg. If it did, we assume
__sync builtins are buggy or otherwise undesirable on this platform,
so uatomic_generic.h will implement uatomic_add_return in terms of
uatomic_cmpxchg too.
- uatomic_xchg is like uatomic_add_return. However, since GCC does
not provide an adequate builtin, it needs to use a compare-and-swap
loop using __sync_bool_compare_and_swap if uatomic_cmpxchg is not
provided.
- uatomic_sub_return/uatomic_add/uatomic_sub will be implemented
in terms of uatomic_add_return;
- uatomic_inc/uatomic_dec will be implemented in terms of uatomic_add.
After this patch, uatomic_generic.h is already used for the latter two
categories. The next patch will use uatomic_generic.h whenever there is
no assembly code involved, or otherwise it makes no difference to use
uatomic_generic.h. We keep custom per-arch macros to provide support for
compilers back to early GCC 3.x versions; however future ports may
not have this limitation.
The hunk in tests/test_uatomic.c is only needed for bisectability
and will be removed later.

From: David Miller <davem@davemloft.net>
Subject: Re: [ltt-dev] Sparc64 support added to Userspace RCU

Date: Thu, 22 Oct 2009 15:57:53 -0400
> Feedback is welcome,
__sparc_v8__ does not mean 64-bit longs or pointers as implied here:
"v8" was the last 32-bit standard of the cpu architecture.
Otherwise looks fine.
Although this port won't be very useful until it can be built in
32-bit mode. As most applications on sparc64 systems are still
32-bit. Like on powerpc, people only rarely build things 64-bit on
sparc64.
You need to build with "-Wa,-Av9a" on the GCC command line for that
case so that the assembler allows the v9 instructions emitted by your
macros, even when building for 32-bit.
Hope this helps.
