sparc: Use popc if possible for hweight routines.

Just like powerpc, we code patch at boot time.

sparc: Minor tweaks to Niagara page copy/clear.

2011-08-03T04:28:32+00:00

Don't use floating point on Niagara2, use the traditional
plain Niagara code instead.

Unroll Niagara loops to 128 bytes for copy, and 256 bytes
for clear.

sparc64: Make rwsems 64-bit.

2010-08-18T05:49:26+00:00

Basically tip-off the powerpc code, use a 64-bit type and atomic64_t
interfaces for the implementation.

This gets us off of the by-hand asm code I wrote, which frankly I
think probably ruins I-cache hit rates.

The idea was the keep the call chains less deep, but anything taking
the rw-semaphores probably is also calling other stuff and therefore
already has allocated a stack-frame.  So no real stack frame savings
ever.

Ben H. has posted patches to make powerpc use 64-bit too and with some
abstractions we can probably use a shared header file somewhere.

With suggestions from Sam Ravnborg.

sparc: Use __builtin_object_size() to validate the buffer size for copy_from_user()

sparc64: fix modpost failure

2009-01-18T07:12:27+00:00

Previously PeeCeeI.o was a library but it
was always pulled in due to insw and friends being exported
(at least for a modular kernel).

But this resulted in modpost failures if there where no in-kernel
users because then insw & friends were not linked in.

Fix this by including PeeCeeI.o in the kernel unconditionally.

The only drawback for this solution is that a nonmodular kernel
will always include insw & friends no matter if they are in use or not.

sparc: Create a new file lib/ksyms.c and add export of all symbols defined in assembler in lib/ to this file.

2009-01-09T00:57:35+00:00

Remove the duplicate entries from kernel/sparc_ksyms_*.c

The rationale behind this is that the EXPORT_SYMBOL() should be close to
their definition and we cannot add designate a symbol to be exported in
assembler so at least put it in a file in the same directory.

sparc: Unify strlen assembler.

2008-12-09T09:07:09+00:00

Use the new asm/asm.h header to help commonize the
strlen assembler between 32-bit and 64-bit

While we're here, use proper linux/linkage.h macros
instead of by-hand stuff.
