Subject: [git pull] cpumask updates for tip/cpus4096
Date: Sat, 27 Dec 2008 03:56:31 -0800 [thread overview]
Message-ID: <495617EF.1040606@sgi.com> (raw)
Hi Ingo,
Please pull the following cpus4096 patches from
git://git.kernel.org/pub/scm/linux/kernel/git/travis/linux-2.6-cpus4096-for-ingo.git master
This gets us near the end of the arch x86 specific changes to accomodate
the new cpumask API. Of the original 4000 or so references to the old
"cpumask_t" API there remains 98 references (which 33 are 'cpumask_t'.)
The ultimate goal remains to allocate variable-sized cpumasks, which will
dramatically reduce the memory usage when running configurations built
for 4096 cpus, on systems which have far fewer cpus present in the system.
The main obstruction is functions that reference cpumask bits using NR_CPUS
instead of nr_cpu_ids.
Included below is the (git) "pull back" of the cpumask patches scheduled
for linux-next to allow integration and testing of more x86-specific
cpumask changes.
Thanks,
Mike
Mike Travis (12):
cpumask: Add alloc_cpumask_var_node()
cpumask: documentation for cpumask_var_t
cpumask: add sysfs displays for configured and disabled cpu maps
sysfs: add documentation to cputopology.txt for system cpumasks
Merge branch 'master' of git://.../rusty/linux-2.6-cpumask into tip/cpus4096
x86: enable cpus display of kernel_max and offlined cpus
x86: cleanup remaining cpumask_t ops in smpboot code
sched: put back some stack hog changes that were undone in kernel/sched.c
x86: cleanup some remaining usages of NR_CPUS where s/b nr_cpu_ids
x86: cleanup remaining cpumask_t code in mce_amd_64.c
x86: cleanup remaining cpumask_t code in microcode_core.c
cpumask: use alloc_cpumask_var_node where appropriate
