2009-09-01locking, m68k/asm-offsets: Rename signal definesHeiko Carstens
In order to be able to use asm-offsets.h in C files the existing namespace conflicts must be solved first. In asm-offsets.h there are defines for signal constants, so they can be used in assembler files. Unfortunately the existing defines use a 1:1 mapping for the macro names which results in name space conflicts if the header file would also be used in C files. So rename the created defines and add an "L" prefix to each one since that has already been done for the SIGTRAP define in entry_mm.

2009-08-31locking, m68k: Calculate thread_info offset with asm offsetHeiko Carstens
m68k has the thread_info structure embedded in its task struct. Therefore its not possible to implement current_thread_info() by looking at the stack pointer and do some simple calculations like most other architectures do it. To return the thread_info pointer for a task two defines are used. This works until the spinlock function bodies get moved into an own header file and CONFIG_SPINLOCK_DEBUG is turned on. That results into this compile error: In file included from include/linux/spinlock.h:378, from include/linux/seqlock.h:29, from include/linux/time.h:8, from include/linux/timex.h:56, from include/linux/sched.h:54, from arch/m68k/kernel/asm-offsets.c:12: include/linux/spinlock_api_smp.h: In function '__spin_unlock_irq': include/linux/spinlock_api_smp.h:371: error: 'current' undeclared (first use in this function) include/linux/spinlock_api_smp.h:371: error: (Each undeclared identifier is reported only once include/linux/spinlock_api_smp.h:371: error: for each function it appears in.) Including asm/current.h to asm-offsets.c wouldn't help since the definition of struct task is needed. So we end up with ugly header file include dependencies. To solve this calculate the offset of the thread_info structure into the task struct in asm-offsets.h and use the offset in task_thread_info(). This works just like it does for IA64 as well.

2009-08-31locking, m68k/asm-offsets: Rename pt_regs offset definesHeiko Carstens
In order to be able to use asm-offsets.h in C files the existing namespace conflicts must be solved first. In asm-offsets.h e.g. PT_D0 gets defined which is the offset of the d0 member of the pt_regs structure. However a same define (with a different meaning) exists in asm/ptregs.h. So rename the defines created with the asm-offset mechanism to PT_OFF_D0 etc. There also already exist a few defines with these names that have the same meaning. So remove the existing defines and use the asm-offset generated ones.

2009-07-09linker script: unify usage of discard definitionTejun Heo
Discarded sections in different archs share some commonality but have considerable differences. This led to linker script for each arch implementing its own /DISCARD/ definition, which makes maintaining tedious and adding new entries error-prone. This patch makes all linker scripts to move discard definitions to the end of the linker script and use the common DISCARDS macro. As ld uses the first matching section definition, archs can include default discarded sections by including them earlier in the linker script. ia64 is notable because it first throws away some ia64 specific subsections and then include the rest of the sections into the final image, so those sections must be discarded before the inclusion. defconfig compile tested for x86, x86-64, powerpc, powerpc64, ia64, alpha, sparc, sparc64 and s390. Michal Simek tested microblaze.

2009-06-24linker script: throw away .discard sectionTejun Heo
x86 throws away .discard section but no other archs do. Also, .discard is not thrown away while linking modules. Make every arch and module linking throw it away. This will be used to define dummy variables for percpu declarations and definitions. This patch is based on Ivan Kokshaysky's alpha percpu patch.

2008-05-18m68k: Correct jump if not running on HP300Geert Uytterhoeven
When running a HP300-enabled kernel on non-HP300 hardware, a test in the early startup code jumps to the wrong label, causing a double bus fault. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-05-05m68k: Handle 68040 bus faultsRoman Zippel
Fix 68040 bus fault handling, so the standard kernel exception handling can be used for i/o probing. Contrary to normal access faults there is nothing to fix, but at least we have to disable writebacks to avoid recursive faults.

2008-05-03unified (weak) sys_pipe implementationUlrich Drepper
This replaces the duplicated arch-specific versions of "sys_pipe()" with one unified implementation. This removes almost 250 lines of duplicated code. It's marked __weak, so that *if* an architecture wants to override the default implementation it can do so by simply having its own replacement version, since many architectures use alternate calling conventions for the 'pipe()' system call for legacy reasons (ie traditional UNIX implementations often return the two file descriptors in registers) I still haven't changed the cris version even though Linus says the BKL isn't needed. The arch maintainer can easily do it if there are really no obstacles. Signed-off-by: Ulrich Drepper <drepper@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-04-17Generic semaphore implementationMatthew Wilcox
Semaphores are no longer performance-critical, so a generic C implementation is better for maintainability, debuggability and extensibility. Thanks to Peter Zijlstra for fixing the lockdep warning. Thanks to Harvey Harrison for pointing out that the unlikely() was unnecessary. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Acked-by: Ingo Molnar <mingo@elte.hu>
