* locking, m68k/asm-offsets: Rename signal definesHeiko Carstens2009-09-011-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* locking, m68k: Calculate thread_info offset with asm offsetHeiko Carstens2009-08-311-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* locking, m68k/asm-offsets: Rename pt_regs offset definesHeiko Carstens2009-08-311-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] m68k: convert thread flags to use bit fieldsRoman Zippel2005-11-131-5/+0
| | | | | | | | | | | | | | | Remove task_work structure, use the standard thread flags functions and use shifts in entry.S to test the thread flags. Add a few local labels to entry.S to allow gas to generate short jumps. Finally it changes a number of inline functions in thread_info.h to macros to delay the current_thread_info() usage, which requires on m68k a structure (task_struct) not yet defined at this point.

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!
