Subject: not needed patch
Date: Wed, 19 Dec 2007 20:57:02 -0800 [thread overview]
Message-ID: <200712192057.02500.yinghai.lu@sun.com> (raw)
Ingo.
commit fbdcf18df73758b2e187ab94678b30cd5f6ff9f9 is not needed.
another patch (by you !! commit 699d934d5f958d7944d195c03c334f28cc0b3669 x86: fixup cpu_info array conversion)
already removed clearing of c->cpu_index. in identify_cpu
also it is not consisent to smpboot_32.c. (it will assign id to cpu_index right after
*c = boot_cpu_data;
)
by revert commit fbdcf18df73758b2e187ab94678b30cd5f6ff9f9, we could use c->cpu_index in identify_cpu.

correct value.
The error shows up in 'cat /proc/cpuinfo' will all cpus = 0.
