[PATCH] Poll cleanups/microoptimizations
The "count" and "pt" variables are declared and modified by do_poll(), as well as accessed and written indirectly in the do_pollfd() subroutine. This patch pulls all handling of these variables into the do_poll() function, thereby eliminating the odd use of indirection in do_pollfd(). This is done by pulling the "struct pollfd" traversal loop from do_pollfd() into its only caller do_poll(). As an added bonus, the patch saves a few clock cycles, and also adds comments to make the code easier to follow.
