Subject: Re: smp_call_function/flush_tlb_all hang on large memory system

In-Reply-To: Your message of "Tue, 23 Nov 2004 07:41:07 +0530." <267988DEACEC5A4D86D5FCD780313FBB2BFBB6@exch-03.noida.hcltech.com>
It has always been an error to call smp_call_function() with interrupts
disabled. Recent 2.6 kernels check for this and issue a warning. The
problem is not smp_call_function() or flush_tlb_all(), it is the code
that called them with interrupts disabled. Find the calling code and
fix it to not disable interrupts.
