* sched: INIT_PREEMPT_COUNTPeter Zijlstra2009-07-102-6/+2
| | | | | | | | | | | | | | | | | | | | | Pull the initial preempt_count value into a single definition site. Maintainers for: alpha, ia64 and m68k, please have a look, your arch code is funny. The header magic is a bit odd, but similar to the KERNEL_DS one, CPP waits with expanding these macros until the INIT_THREAD_INFO macro itself is expanded, which is in arch/*/kernel/init_task.c where we've already included sched.h so we're good.

| * kmap_types: make most arches use generic header fileRandy Dunlap2009-06-161-16/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert most arches to use asm-generic/kmap_types.h. Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h, controlled by __WITH_KM_FENCE from each arch's kmap_types.h file. Would be nice to be able to add custom KM_types per arch, but I don't yet see a nice, clean way to do that. Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and 68k(tonyb). Note: avr32 should be able to remove KM_PTE2 (since it's not used) and then just use the generic kmap_types.h file. Get avr32 maintainer approval.

| | | | | | | | | | | | | | | | | | | | | | Now that we defer the cpu_data() initializations to the end of per-cpu setup, we can get rid of this local hack we had to setup the per-cpu areas eary.

We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.

These could cause future problems if other modules get loaded into that memory and cause an exception as we'd see the wrong fixup. The only case I know of is kvm-intel.ko (when CONFIG_CC_OPTIMIZE_FOR_SIZE=n). Amerigo fixed this long-standing FIXME in the x86 version, but this patch is more general. This implements trim_init_extable(); most archs are simple since they use the standard lib/extable.c sort code. Alpha and IA64 use relative addresses in their fixups, so thier trimming is a slight variation. Sparc32 is unique; it doesn't seem to define ARCH_HAS_SORT_EXTABLE, yet it defines its own sort_extable() which overrides the one in lib. It doesn't sort, so we have to mark deleted entries instead of actually trimming them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Makes code futureproof against the impending change to mm->cpu_vm_mask. It's also a chance to use the new cpumask_ ops which take a pointer (the older ones are deprecated, but there's no hurry for arch code). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

One day gcc could bite us over this usage (though we seem to have gotten away with it so far). So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR with the modern "cpu_all_mask" (a real struct cpumask *), and remove CPU_MASK_ALL_PTR altogether. Also remove the confusing and deprecated large-NR_CPUS-only "cpu_mask_all".
