[uml-devel] [PATCH 4/5] uml: revert "run mconsole "sysrq" in process context"

[Paolo 'B. G. <bla...@ya...>]

From: Paolo 'Blaisorblade' Giarrusso <bla...@ya...>

Revert commit 12ebcd73e40e09f0dfddf89e465cc0541e0ff8b1, i.e. 
[PATCH] uml: run mconsole "sysrq" in process context
on request from Jeff Dike.

a) sysrq may be run when the scheduler is non-functioning

b) the warning I wanted to fix actually came from the fault handler run in
atomic context. But I fixed that not to take the semaphore in a separate patch.

c) the fault handler is run because of a fault, and that fault was unaffected by
this patch.
