* sh: Add support for SH7723 CPU subtype.Paul Mundt2008-04-181-1/+2
| | | | | | This adds basic support for the SH7723 MobileR2 CPU. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Fix occasional FPU register corruption under preempt.Paul Mundt2008-03-261-1/+0
| | | | | | | | | | | Presently with preempt enabled there's the possibility to be preempted after the TIF_USEDFPU test and the register save, leading to bogus state post-__switch_to(). Use an explicit preempt_disable()/enable() pair around unlazy_fpu()/clear_fpu() to avoid this. Follows the x86 change.

* sh: add support for sh7366 processorMagnus Damm2008-02-141-1/+1
| | | | | | | | This patch adds sh7366 cpu supports. Just the most basic things like interrupt controller, clocks and serial port are included at this point. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Add SH7263 CPU support.Paul Mundt2008-01-281-1/+1
| | | | | | | | | | | | This adds support for the SH7263 (SH-2A) CPU. This particular CPU is a superset of SH7203, adding some additional peripheral blocks and hooking up additional (reserved on SH7203) vectors in the INTC block. No visibly nasty surprises, yet..

* sh: Kill off the remaining ST40 cruft.Paul Mundt2007-11-071-1/+1
| | | | | | | | | | | | | The ST40 stuff in-tree hasn't built for some time, and hasn't been updated for over 3 years. ST maintains their own out-of-tree changes and rebases occasionally, and that's ultimately where all of the ST40 users go anyways. In order for the ST40 code to be brought up to date most of the stuff removed in this changeset would have to be rewritten anyways, so there's very little benefit in keeping the remnants around either.

* sh: Use generic SMP_CACHE_BYTES/L1_CACHE_ALIGN.Paul Mundt2007-10-301-1/+1

* sh: Use boot_cpu_data for CPU probe.Paul Mundt2007-09-271-1/+0
| | | | | | | | | | This moves off of smp_processor_id() and only sets the probe information for the boot CPU directly. This will be copied out for the secondaries, so there's no reason to do this each time. This also allows for some header tidying. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: processor.h needs smp.hPaul Mundt2007-09-271-0/+1
| | | | | | Trivial build fix for SH-2. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off special boot_cpu_data.Paul Mundt2007-09-211-7/+2
| | | | | | | | This consolidates the cpu_data definitions and gets rid of the special boot_cpu_data. It's made a wrapper to the boot CPU, in order to keep the existing in-tree users happy. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add SH7720 CPU support.Markus Brunner2007-09-211-1/+1

* sh: Preliminary support for the SH-X3 CPU.Paul Mundt2007-06-201-1/+1
| | | | | | This adds basic support for UP SH-X3. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Tidy up dependencies for SH-2 build.Paul Mundt2007-06-111-4/+0
| | | | | | | | | | | | SH-2 can presently get in to some pretty bogus states, so we tidy up the dependencies a bit and get it all building again. This gets us a bit closer to a functional allyesconfig and allmodconfig, though there are still a few things to fix up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off dead SH7604 support.Paul Mundt2007-06-081-1/+1
| | | | | | | | This was added during 2.5.x, but was never moved along. This can easily be resurrected if someone has one they wish to work with, but it's not worth keeping around in its current form. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Fixup cpu_data references for the non-boot CPUs.Paul Mundt2007-02-131-2/+3
| | | | | | | There are a lot of bogus cpu_data-> references that only end up working for the boot CPU, convert these to current_cpu_data to fixup SMP. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Use a per-cpu ASID cache.Paul Mundt2007-02-131-0/+1
| | | | | | | | Previously this was implemented using a global cache, cache this per-CPU instead and bump up the number of context IDs to match NR_CPUS. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: SH-MobileR SH7722 CPU support.Paul Mundt2006-12-121-2/+6

* sh: KSTK_EIP/KSTK_ESP consistency.Stuart Menefy2006-12-061-2/+2
| | | | | | | | | | | | | | | | | | | | | Two of the fields in /proc/[number]/stat are documented in proc(5) as: kstkesp %lu The current value of esp (stack pointer), as found in the kernel stack page for the process. kstkeip %lu The current EIP (instruction pointer). The SH currently prints the the last SP and PC of the process inside the kernel, while most other archs use the last user space values. This patch modifes the SH to display the user space values.

* sh: Set up correct siginfo structures for page faults.Stuart Menefy2006-12-061-9/+3
| | | | | | | | Remove the previous saving of fault codes into the thread_struct as they are never used, and appeared to be inherited from x86. Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Proper show_stack/show_trace() implementation.Paul Mundt2006-10-191-0/+2
| | | | | | | | | | This splits out some of the previous show_stack() implementation which was mostly doing the show_trace() work without actually dumping any of the stack contents. This now gets split in to two sections, where we do the fetching of the stack pointer and subsequent stack dumping in show_stack(), while moving the call trace in to show_trace(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* 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

* 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>

* [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.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+275
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!
