Analyze and fix the following issue in the Linux kernel code: [POWERPC] spufs: Fix lost events in poll/epoll on mfc
Problem Details: When waiting for I/O events on mfc in an SPU context by using poll/epoll syscalls, some of the events can be lost because of wrong order of poll_wait and MFC status checks in the spufs_mfc_poll function and non-atomic update of tagwait.
