x86, ia64, smp: use workqueues unconditionally during do_boot_cpu()

2010-08-10T03:45:06+00:00

Workqueues are now initialized as part of the early_initcall().  So they
are available for use during cold boot process aswell.

topology: alternate fix for ia64 tiger_defconfig build breakage

2010-08-10T03:44:57+00:00

Define stubs for the numa_*_id() generic percpu related functions for
non-NUMA configurations in  where the other
non-numa stubs live.

Fixes ia64 !NUMA build breakage -- e.g., tiger_defconfig

Back out now unneeded '#ifndef CONFIG_NUMA' guards from ia64 smpboot.c

workqueue: increase max_active of keventd and kill current_is_keventd()

2010-06-29T08:07:14+00:00

Define WQ_MAX_ACTIVE and create keventd with max_active set to half of
it which means that keventd now can process upto WQ_MAX_ACTIVE / 2 - 1
works concurrently.  Unless some combination can result in dependency
loop longer than max_active, deadlock won't happen and thus it's
unnecessary to check whether current_is_keventd() before trying to
schedule a work.  Kill current_is_keventd().

(Lockdep annotations are broken.  We need lock_map_acquire_read_norecurse())

[IA64] Fix build breakage

2010-05-27T22:35:13+00:00

In commit 0ac0c0d0f837c499afd02a802f9cf52d3027fa3b
cpusets: randomize node rotor used in cpuset_mem_spread_node()

Jack Steiner fixed a problem with too many small tasks being
assigned to node 0. Copy his code to ia64 to avoid build error.

    arch/ia64/kernel/smpboot.c:641: error: ‘cpu_to_node_map’ undeclared (first use in this function)

numa: ia64: use generic percpu var numa_node_id() implementation

Lee Schermerhorn added some set_numa_node() calls - but these
only work on CONFIG_NUMA=y configurations. Surround the calls
with #ifdef CONFIG_NUMA

numa: ia64: support numa_mem_id() for memoryless nodes

2010-05-27T16:12:57+00:00

Enable 'HAVE_MEMORYLESS_NODES' by default when NUMA configured on ia64.
Initialize percpu 'numa_mem' variable when starting secondary cpus.
Generic initialization will handle the boot cpu.

Nothing uses 'numa_mem_id()' yet.  Subsequent patch with modify slab to
use this.

[IA64] Remove COMPAT_IA32 support

2010-02-08T18:42:17+00:00

This has been broken since May 2008 when Al Viro killed altroot support.
Since nobody has complained, it would appear that there are no users of
this code (A plausible theory since the main OSVs that support ia64 prefer
to use the IA32-EL software emulation).
