alpha: fix hard_smp_processor_id compile error

2007-05-15T15:54:00+00:00

"Remove hardcoding of hard_smp_processor_id on UP systems",
2f4dfe206a2fc07099dfad77a8ea2f4b4ae2140f in Linus' tree, moved
the definition of hard_smp_processor_id linux/smp.h to asm/smp.h
for UP systems. This causes a regression on Alpha.

cc1: warnings being treated as errors
arch/alpha/kernel/setup.c: In function 'setup_arch':
arch/alpha/kernel/setup.c:506: warning: implicit declaration of function 'hard_smp_processor_id'
make[1]: *** [arch/alpha/kernel/setup.o] error 1
make: *** [arch/alpha/kernel] error 2

By including asm/smp.h non-conditionally in asm/mmu_context.h
the problem appears to be resolved.

Consolidate asm/poll.h

2007-05-11T15:29:34+00:00

These files are almost all the same.

This patch could be made even simpler if we don't mind POLLREMOVE turning
up in a few architectures that didn't have it previously (which should be
OK as POLLREMOVE is not used anywhere in the current tree).

rename thread_info to stack

2007-05-09T19:30:56+00:00

This finally renames the thread_info field in task structure to stack, so that
the assumptions about this field are gone and archs have more freedom about
placing the thread_info structure.

Nonbroken archs which have a proper thread pointer can do the access to both
current thread and task structure via a single pointer.

It'll allow for a few more cleanups of the fork code, from which e.g.  ia64
could benefit.

Remove hardcoding of hard_smp_processor_id on UP systems

2007-05-09T19:30:48+00:00

With the advent of kdump, the assumption that the boot CPU when booting an UP
kernel is always the CPU with a particular hardware ID (often 0) (usually
referred to as BSP on some architectures) is not valid anymore.  The reason
being that the dump capture kernel boots on the crashed CPU (the CPU that
invoked crash_kexec), which may be or may not be that particular CPU.

Move definition of hard_smp_processor_id for the UP case to
architecture-specific code ("asm/smp.h") where it belongs, so that each
architecture can provide its own implementation.

atomic.h: atomic_add_unless as inline. Remove system.h atomic.h circular dependency

2007-05-08T18:15:20+00:00

atomic_add_unless as inline. Remove system.h atomic.h circular dependency.
I agree (with Andi Kleen) this typeof is not needed and more error
prone. All the original atomic.h code that uses cmpxchg (which includes
the atomic_add_unless) uses defines instead of inline functions,
probably to circumvent a circular dependency between system.h and
atomic.h on powerpc (which my patch addresses). Therefore, it makes
sense to use inline functions that will provide type checking.

atomic_add_unless as inline. Remove system.h atomic.h circular dependency.
Digging into the FRV architecture shows me that it is also affected by
such a circular dependency. Here is the diff applying this against the
rest of my atomic.h patches.

It applies over the atomic.h standardization patches.

atomic.h: add atomic64 cmpxchg, xchg and add_unless to alpha

2007-05-08T18:15:19+00:00

This series mainly adds support for missing 64 bits cmpxchg and 64 bits atomic
add unless.  Therefore, principally 64 bits architectures are targeted by
these patches.  It also adds the complete list of atomic operations on the
atomic_long type.

Clean up mostly unused IOSPACE macros

2007-05-08T18:15:13+00:00

Most architectures defined three macros, MK_IOSPACE_PFN(), GET_IOSPACE()
and GET_PFN() in pgtable.h.  However, the only callers of any of these
macros are in Sparc specific code, either in arch/sparc, arch/sparc64 or
drivers/sbus.

This patch removes the redundant macros from all architectures except
sparc and sparc64.

move die notifier handling to common code

2007-05-08T18:15:04+00:00

This patch moves the die notifier handling to common code.  Previous
various architectures had exactly the same code for it.  Note that the new
code is compiled unconditionally, this should be understood as an appel to
the other architecture maintainer to implement support for it aswell (aka
sprinkling a notify_die or two in the proper place)

arm had a notifiy_die that did something totally different, I renamed it to
arm_notify_die as part of the patch and made it static to the file it's
declared and used at.  avr32 used to pass slightly less information through
this interface and I brought it into line with the other architectures.
