2008-12-04sparc,sparc64: unify kernel/Sam Ravnborg
o Move all files from sparc64/kernel/ to sparc/kernel - rename as appropriate o Update sparc/Makefile to the changes o Update sparc/kernel/Makefile to include the sparc64 files NOTE: This commit changes link order on sparc64! Link order had to change for either of sparc32 and sparc64. And assuming sparc64 see more testing than sparc32 change link order on sparc64 where issues will be caught faster.

2006-03-05[SPARC64]: Mark __ex_table section correctly.David S. Miller
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. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-09-29[SPARC64]: Fix fault handling in unaligned trap handler.David S. Miller
We were not calling kernel_mna_trap_fault() correctly. Instead of being fancy, just return 0 vs. -EFAULT from the assembler stubs, and handle that return value as appropriate. Create an "__retl_efault" stub for assembler exception table entries and use it where possible. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-09-20[SPARC64]: Handle little-endian unaligned loads/stores correctly.David S. Miller
Because we use byte loads/stores to cons up the value in and out of registers, we can't expect the ASI endianness setting to take care of this for us. So do it by hand. This case is triggered by drivers/block/aoe/aoecmd.c in the ataid_complete() function where it goes: /* word 100: number lba48 sectors */ ssize = le64_to_cpup((__le64 *) &id[100<<1]); This &id[100<<1] address is 4 byte, rather than 8 byte aligned, thus triggering the unaligned exception.

2005-08-19[SPARC64]: Move kernel unaligned trap handlers into assembler file.David S. Miller
GCC 4.x really dislikes the games we are playing in unaligned.c, and the cleanest way to fix this is to move things into assembler. Noted by Al Viro. Signed-off-by: David S. Miller <davem@davemloft.net>
