2006-06-26[PATCH] m68knommu: use configurable RAM setup in start up codeGreg Ungerer
Change to using a configurable RAM setup in startup code. This cleans up the whole RAM base/sizing issue, and removes a lot of board specific code. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-06-26[PATCH] m68knommu: use configurable RAM setup in linker scriptGreg Ungerer
Remove the fixed RAM configurations for each board type from the linker script. Replace with simple defines usng the flexible RAM configuration options. This cleans out of lot of board specific munging of addresses. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-06-26[PATCH] m68knommu: create configurable RAM setupGreg Ungerer
Reworked the way RAM regions are defined. Instead of coding all the variations for each board type we now just configure RAM base and size in the usual Kconfig setup. This much simplifies the code, and makes it a lot more flexible when setting up new boards or board varients.

2006-06-26[PATCH] m68knommu: remove unused vars from generic 68328 start codeGreg Ungerer

2006-06-25[PATCH] m68knommu: improve syscall entry and fix stracePhilippe De Muyter
Here is a patch to the system call handling for 5307/5272/etc to: - fix the strace support (one tested the wrong bit) - make all system calls a little bit faster by inlining set_esp0 and supporting ENOSYS out of the critical path. - remove extraneous spaces Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

A cleanup of m68knommu/kernel/setup.c : - No need to initialize global pointers to NULL, they will have that value automatically, and they eat up space in my data segment image in FLASH. - Remove get_cpuinfo.

Switch to naming the architecture config options for the m68knommu branch as "M68K", dropping "M68KNOMMU".

2006-06-23[PATCH] fix incorrect SA_ONSTACK behaviour for 64-bit processesLaurent MEYER
- When setting a sighandler using sigaction() call, if the flag SA_ONSTACK is set and no alternate stack is provided via sigaltstack(), the kernel still try to install the alternate stack. This behavior is the opposite of the one which is documented in Single Unix Specifications V3. - Also when setting an alternate stack using sigaltstack() with the flag SS_DISABLE, the kernel try to install the alternate stack on signal delivery. These two use cases makes the process crash at signal delivery.

2006-04-11[PATCH] No arch-specific strpbrk implementationsKyle McMartin
While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't being exported from lib/string.c. Investigating further, I noticed a changeset that removed its export and added it to _ksyms.c on a few more architectures. The justification was that "other arches do it." I think this is wrong, since no architecture currently defines __HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it themselves. Therefore, consolidate the export to lib/string.c.

include/linux/platform.h contained nothing that was actually used except the default_idle() prototype, and is therefore removed by this patch.

2006-03-22[PATCH] remove set_page_count() outside mm/Nick Piggin
set_page_count usage outside mm/ is limited to setting the refcount to 1. Remove set_page_count from outside mm/, and replace those users with init_page_count() and set_page_refcounted().

2006-02-14[PATCH] hrtimer: round up relative start time on low-res archesIngo Molnar
CONFIG_TIME_LOW_RES is a temporary way for architectures to signal that they simply return xtime in do_gettimeoffset().

2006-01-10[PATCH] m68knommu: fix a5 reg corruption in signal handlersGreg Ungerer
This is a patch adapted from a posting by Andrea Tarani which was pointed out to me by Bernardo Innocenti. Thanks to both of them for their help and patience. The original posting is here: http://mailman.uclinux.org/pipermail/uclinux-dev/2005-July/033543.html The problem first manifest itself as busybox ping terminating with an "Illegal instruction". I reduced this to a test case and found that variable size arrays allocated on the stack could lead to stacks not aligned on 32 bit boundaries. For the Coldfire this proved fatal. Having been pointed out this patch by Bernardo, I applied it and it fixed the first test case. I then went back to busybox's ping. This still failed with "Illegal instruction", but in a different way. Before it depended on the size allocated for the ping buffer, now it happened every time. I also found it depended on optimisation level (gcc-3.4.0) -Os was okay but not -O2. After a lot of looking, it turned out that register a5 was being corrupted by the signal handler (after applying the patch). I re-worked the patch a bit to save/restore a5 and now all seems well.

2005-11-07[PATCH] consolidate sys_ptrace()Christoph Hellwig
The sys_ptrace boilerplate code (everything outside the big switch statement for the arch-specific requests) is shared by most architectures. This patch moves it to kernel/ptrace.c and leaves the arch-specific code as arch_ptrace. Some architectures have a too different ptrace so we have to exclude them. They continue to keep their implementations. For sh64 I had to add a sh64_ptrace wrapper because it does some initialization on the first call. For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.
