Analyze and fix the following issue in the Linux kernel code: [POWERPC] Fix deadlock with mmu_hash_lock in hash_page_sync
Problem Details: hash_page_sync() takes and releases the low level mmu hash lock in order to sync with other processors disposing of page tables. Because that lock can be needed to service hash misses triggered by interrupt handlers, taking it must be done with interrupts off. However, hash_page_sync() appears to be ...

Problem Details: This may lead to situations, when each of two proc entries produce data for the other's device. Looks like a BUG, so this patch is for net-2.6.
