* MN10300: Specify an ELF HWCAP flag for MN10300 Atomic Operations Unit supportMark Salter2010-10-271-0/+10
| | | | | | | | Use an ELF HWCAP flag to indicate to the process that the CPU provides LL/SC equivalent atomic operations unit support in addition to BSET/BCLR. Signed-off-by: Mark Salter <msalter@redhat.com> Signed-off-by: David Howells <dhowells@redhat.com>
* MN10300: Make the FPU operate in non-lazy mode under SMPAkira Takeuchi2010-10-271-2/+0
| | | | | | | | | | Make the FPU operate in non-lazy mode under SMP so that when the process that is currently using the FPU migrates to a different CPU, we don't have to ping its previous CPU to flush the FPU context.

* elf: kill USE_ELF_CORE_DUMPChristoph Hellwig2009-12-161-1/+0
| | | | | | | | | | | | | Currently all architectures but microblaze unconditionally define USE_ELF_CORE_DUMP. The microblaze omission seems like an error to me, so let's kill this ifdef and make sure we are the same everywhere.

* MN10300: Add support for new ELF relocs in kernel modulesMark Salter2009-06-181-0/+2
| | | | | | | | | Add support for new relocs which may show up in MN10300 kernel modules due to linker relaxation. Signed-off-by: Mark Salter <msalter@redhat.com> Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
