sparc64: Fix DAX handling via userspace access from kernel.

2009-03-17T00:31:55Z

[ Upstream commit fcd26f7ae2ea5889134e8b3d60a42ce8b993c95f ] If we do a userspace access from kernel mode, and get a data access exception, we need to check the exception table just like a normal fault does. The spitfire DAX handler was doing this, but such logic was missing from the sun4v DAX code. Reported-by: Dennis Gilmore Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

Remove attribute((weak)) from sys_pipe/sys_pipe2

2009-01-18T18:43:51Z

commit 1134723e96f6e2abcf8bfd7a2d1c96fcc323ef35 upstream. Remove __attribute__((weak)) from common code sys_pipe implemantation. IA64, ALPHA, SUPERH (32bit) and SPARC (32bit) have own implemantations with the same name. Just rename them. For sys_pipe2 there is no architecture specific implementation.

sparc64: Fix VIS emulation bugs

2008-12-04T03:36:05Z

This patch fixes some bugs in VIS emulation that cause the GCC test failure FAIL: gcc.target/sparc/pdist-3.c execution test for both 32-bit and 64-bit testing on hardware lacking these instructions. The emulation code for the pdist instruction uses RS1(insn) for both source registers rs1 and rs2, which is obviously wrong and leads to the instruction doing nothing (the observed problem), and further inspection of the code shows that RS1 uses a shift of 24 and RD a shift of 25, which clearly cannot both be right; examining SPARC documentation indicates the correct shift for RS1 is 14. This patch fixes the bug if single-stepping over the affected instruction in the debugger, but not if the testcase is run standalone. For that, Wind River has another patch I hope they will send as a followup to this patch submission. Signed-off-by: Joseph Myers Signed-off-by: David S. Miller

sparc64: Fix bug in PTRACE_SETFPREGS64 handling.

2008-12-03T08:47:28Z

From: Chris Torek >The SPARC64 kernel code for PTRACE_SETFPREGS64 appears to be an exact copy >of that for PTRACE_GETFPREGS64. This means that gdbserver and native >64-bit GDB cannot set floating-point registers. It looks like a simple typo. Signed-off-by: David S. Miller

Revert "of_platform_driver noise on sparce"

This reverts commit e669dae6141ff97d3c7566207f5de3b487dcf837, since it is incomplete, and clashes with fuller patches and the sparc 32/64 unification effort. Requested-by: David Miller Acked-by: Al Viro Signed-off-by: Linus Torvalds
