sparc64: Remove RWSEM export leftovers

2013-10-26T20:06:09Z

[ Upstream commit 61d9b9355b0d427bd1e732bd54628ff9103e496f ] The functions __down_read __down_read_trylock __down_write __down_write_trylock __up_read __up_write __downgrade_write are implemented inline, so remove corresponding EXPORT_SYMBOLs (They lead to compile errors on RT kernel).

sparc32: Add ucmpdi2.o to obj-y instead of lib-y.

2013-09-10T00:57:40Z

commit 74c7b28953d4eaa6a479c187aeafcfc0280da5e8 upstream. Otherwise if no references exist in the static kernel image, we won't export the symbol properly to modules. Signed-off-by: David S. Miller Cc: Guenter Roeck Signed-off-by: Greg Kroah-Hartman Signed-off-by: Ben Hutchings

sparc32: add ucmpdi2

2013-09-10T00:57:39Z

commit de36e66d5fa52bc6e2dacd95c701a1762b5308a7 upstream. Based on copy from microblaze add ucmpdi2 implementation. This fixes build of niu driver which failed with: drivers/built-in.o: In function `niu_get_nfc': niu.c:(.text+0x91494): undefined reference to `__ucmpdi2' This driver will never be used on a sparc32 system, but patch added to fix build breakage with all*config builds.

sparc: Minor tweaks to Niagara page copy/clear.

2011-08-03T04:28:32Z

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. Signed-off-by: David S. Miller
