* sparc32: drop sun4c user stack checking routineSam Ravnborg2012-05-111-70/+6
| | | | | | | | With this we no longer do any run-time patchings of traps. So drop the function + macro to support this. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: keep calling do_signal() as long as pending signals remainAl Viro2010-10-261-3/+3
| | | | | | | | | | | | Analog of what commit 494486a1d2697f2153199b6501ab5b4d6e15a2bb had done to alpha (another architecture with similar bug). One note: in rtrap_32.S part clr %l6 has been a rudiment of left after commit 28e6103665301ce60634e8a77f0b657c6cc099de (sparc: Fix debugger syscall restart interactions) has killed %l6 use in there.

* sparc: prepare kernel/ for unificationSam Ravnborg2008-12-041-0/+322
o sparc32 files with identical names to sparc64 renamed to <name>_32.S o introduced a few Kconfig helpers to simplify Makefile logic o refactored Makefile to prepare for unification - use obj-$(CONFIG_SPARC32) for sparc32 specific files - use <name>_$(BITS) for files where sparc64 has a _64 variant - sparc64 directly include a few files where sparc32 builds them, refer to these files directly (no BITS) - sneaked in -Werror as used by sparc64 o modified sparc/Makefile to use the new names for head/init_task Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.
