Just FYI, I'm currently trying to resolve a build failure
that was introduced in the past 24 hours in Linus's tree
for sparc64:
CC drivers/base/topology.o
drivers/base/topology.c: In function ‘show_physical_package_id’:
drivers/base/topology.c:103: error: implicit declaration of function ‘cpu_data’
drivers/base/topology.c:103: error: request for member ‘proc_id’ in something not a structure or union
drivers/base/topology.c: In function ‘show_core_id’:
drivers/base/topology.c:106: error: request for member ‘core_id’ in something not a structure or union
make[1]: *** [drivers/base/topology.o] Error 1
make: *** [drivers/base/topology.o] Error 2
It's not simple to fix this, the "easy" idea to simply include
asm/cpudata.h into asm/topology_64.h for the SMP case doesn't work
at all:
CC drivers/base/topology.o

What a mess...
Anyways, once I have this sorted I'll merge the sparc-2.6 tree with
Linus's and push that out to kernel.org
