linux/include/asm-x86/ipi.h, branch v2.6.25Linux Kernel (branches are rebased on master from time to time)https://sre.ring0.de/linux/atom?h=v2.6.252007-10-19T18:35:03Zx86: convert cpu_to_apicid to be a per cpu variable2007-10-19T18:35:03ZMike Travistravis@sgi.com2007-10-19T18:35:03Zurn:sha1:71fff5e6ca1b738ac4742580e4c0ff79d906f6c8
This patch converts the x86_cpu_to_apicid array to be a per cpu
variable. This saves sizeof(apicid) * NR unused cpus. Access is mostly
from startup and CPU HOTPLUG functions.
MP_processor_info() is one of the functions that require access to the
x86_cpu_to_apicid array before the per_cpu data area is setup. For this
case, a pointer to the __initdata array is initialized in setup_arch()
and removed in smp_prepare_cpus() after the per_cpu data area is
initialized.
A second change is included to change the initial array value of ARCH
i386 from 0xff to BAD_APICID to be consistent with ARCH x86_64.
