* sh: Initial vsyscall page support.Paul Mundt2006-09-271-0/+6
| | | | | | | | | | This implements initial support for the vsyscall page on SH. At the moment we leave it configurable due to having nommu to support from the same code base. We hook it up for the signal trampoline return at present, with more to be added later, once uClibc catches up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Support for L2 cache on newer SH-4A CPUs.Paul Mundt2006-09-271-4/+5
| | | | | | | This implements preliminary support for the L2 caches found on newer SH-4A CPUs. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: CPU flags in AT_HWCAP in ELF auxvt.Paul Mundt2006-09-271-11/+1
| | | | | | Encode processor flags in AT_HWCAP in the ELF auxiliary vector. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add support for SH7706/SH7710/SH7343 CPUs.Paul Mundt2006-09-271-3/+5
| | | | | | | This adds support for the aforementioned CPU subtypes, and cleans up some build issues encountered as a result. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fixup __strnlen_user() behaviour.Paul Mundt2006-09-271-0/+4
| | | | | | | | | | Drop TIF_USERSPACE and add addr_limit to the thread_info struct. Subsequently, use that for address checking in strnlen_user() to ward off bogus -EFAULTs. Make __strnlen_user() return 0 on exception, rather than -EFAULT. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: prefetch()/prefetchw() support.Paul Mundt2006-09-271-0/+13
| | | | | | SH-2/3/4 are able to prefetch, add support for it.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* [PATCH] Make cpu_relax() imply barrier() on all archesChase Venters2006-07-121-1/+2
| | | | | | | | | | | | | During the recent discussion of taking 'volatile' off of the spinlock, I noticed that while most arches #define cpu_relax() such that it implies barrier(), some arches define cpu_relax() to be empty. This patch changes the definition of cpu_relax() for frv, h8300, m68knommu, sh, sh64, v850 and xtensa from an empty while(0) to the compiler barrier().

* [PATCH] sh: Cleanup struct sh_cpuinfo for clock framework changesPaul Mundt2006-02-011-21/+15
| | | | | | | | | | | | Now that the clock framework changes have been integrated, the manual clock accounting that was done in sh_cpuinfo can be dropped. Also correct a bug with running past the end of the CPU flags when there's a mismatch between the added flags and printed ones.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
