Rename kcpuset_copybits() to kcpuset_export_u32() and thus be more specific
about the interface.

kcpuset_copybits: fix potential endianness problem.  Spotted by matt@.

Few fixes for Xen:
- cpu_load_pmap: use atomic kcpuset(9) operations; fixes rare crashes.
- Add kcpuset_copybits(9) and replace xen_kcpuset2bits().  Avoids incorrect
  ncpu problem in early boot.  Also, micro-optimises xen_mcast_invlpg() and
  xen_mcast_tlbflush() routines.

Tested by chs@.

- Convert x86 MD code, mainly pmap(9) e.g. TLB shootdown code, to use
  kcpuset(9) and thus replace hardcoded CPU bitmasks.  This removes the
  limitation of maximum CPUs.

- Support up to 256 CPUs on amd64 architecture by default.

Bug fixes, improvements, completion of Xen part and testing on 64-core
AMD Opteron(tm) Processor 6282 SE (also, as Xen HVM domU with 128 CPUs)

Revision 1.1 / (download) - annotate - [select for diffs], Sun Aug 7 13:33:01 2011 UTC (21 months, 1 week ago) by rmind
Branch: MAIN

Add kcpuset(9) - a reworked dynamic CPU set implementation for kernel.
Suitable for use during the early boot.  MD and other implementations
should be replaced with this interface.
