Subject: [PATCH] arch: um: convert tasklets to use new tasklet_setup() API

From: Allen Pais <allen.lkml@...il.com>

In preparation for unconditionally passing the
struct tasklet_struct pointer to all tasklet
callbacks, switch to using the new tasklet_setup()
and from_tasklet() to pass the tasklet pointer explicitly.
