  s390x/kvm: Fix opcode decoding for eb instruction handler

The second byte of the opcode is encoded in the lowest byte of the ipb
field, not the lowest byte of the ipa field.

  s390x/kvm: Fix warning from sparse

When running "sparse" with the s390x kvm.c code, it complains that
"constant 0x00400f1d40330000 is so big it is long" - let's fix this
by appending a proper suffix.

  s390x/sclpconsole-lm: truncate input if line is too long

As the SCLP line mode console input length is limited by the available
SCCB buffer space, it might lock up if the input does not fit into the
buffer.

With this patch, characters that don't fit are 'eaten' up to the next
CR/LF and the input line is sent truncated to the guest.

  s390x/sclpconsole-lm: Fix hanging SCLP line mode console

Trigger recalculating sets of file descriptors for the main loop's poll()
in order to make sure a possibly removed FD 0 from the poll() file
descriptor array is re-added. FD 0 is removed from the decriptor array
when the console's can_read() callback returns 0.

  s390x/sclpconsole: Avoid hanging SCLP ASCII console

Force recalculation of file descriptor sets for main loop's poll(),
in order to be able to readd a possibly removed input file descriptor
after can_read() returned 0 (zero).
