all-archs: consolidate .data section definition in asm-generic

2007-05-19T07:11:57+00:00

With this consolidation we can now modify the .data
section definition in one spot for all archs.

Slab allocators: define common size limitations

2007-05-17T12:23:04+00:00

Currently we have a maze of configuration variables that determine the
maximum slab size.  Worst of all it seems to vary between SLAB and SLUB.

So define a common maximum size for kmalloc.  For conveniences sake we use
the maximum size ever supported which is 32 MB.  We limit the maximum size
to a lower limit if MAX_ORDER does not allow such large allocations.

For many architectures this patch will have the effect of adding large
kmalloc sizes.  x86_64 adds 5 new kmalloc sizes.  So a small amount of
memory will be needed for these caches (contemporary SLAB has dynamically
sizeable node and cpu structure so the waste is less than in the past)

Most architectures will then be able to allocate object with sizes up to
MAX_ORDER.  We have had repeated breakage (in fact whenever we doubled the
number of supported processors) on IA64 because one or the other struct
grew beyond what the slab allocators supported.  This will avoid future
issues and f.e.  avoid fixes for 2k and 4k cpu support.

CONFIG_LARGE_ALLOCS is no longer necessary so drop it.

It fixes sparc64 with SLAB.

FRV: Replace pgd management via slabs through quicklists

2007-05-09T19:30:46+00:00

This is done in order to be able to run SLUB which expects no modifications
to its page structs.

FRV: Miscellaneous fixes

2007-05-09T03:41:14+00:00

Miscellaneous fixes to bring FRV up to date:

 (1) Copy the new syscall numbers from i386 to asm-frv/unistd.h and fill out
     the syscall table in entry.S too.

 (2) Mark __frv_uart0 and __frv_uart1 __pminitdata rather than __initdata so
     that determine_clocks() can access them when CONFIG_PM=y.

 (3) Make arch/frv/mm/elf-fdpic.c include asm/mman.h so that MAP_FIXED is
     available (fixes commit 2fd3bebaad9da3b3b99c46a3389099424bf7ee35).

header cleaning: don't include smp_lock.h when not used

2007-05-08T18:15:07+00:00

Remove includes of  where it is not used/needed.
Suggested by Al Viro.

Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,
sparc64, and arm (all 59 defconfigs).

kconfig: centralize the selection of semaphore debugging in lib/Kconfig.debug

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

Remove the Kconfig selection of semaphore debugging from the ALPHA and FRV
Kconfig files, and centralize it in lib/Kconfig.debug.

There doesn't seem to be much point in letting individual architectures
independently define the same Kconfig option when it can just as easily be
put in a single Kconfig file and made dependent on a subset of
architectures.  that way, at least the option shows up in the same relative
location in the menu each time.
