Change summaries:

285621 by jhibbits:
Fix formatting.

285620 by jhibbits:
Fix userland program exception handling for powerpc64.

It appears that the linker will not handle 64-bit relocations at addresses that
are not aligned to 8-byte boundaries.  Prior to this change the line:

  .llong generictrap

was aligned to a 4-byte address, and the linker replaced that with an 8-byte
0x0.  Aligning that address to 8 bytes caused the linker to generate the proper
relocation.  As a follow-through, the dblow from trap_subr33.S used the code
sequence 'lwz %r1, TRAP_GENTRAP(0)', so this reproduces the analogue of that for
64-bit.

285619 by neel:
If uart interrupts are not functioning then schedule the callout to do the
polling at device attach time [1].

Add tunables 'debug.uart_force_poll' and 'debug.uart_poll_freq' to control
uart polling.

285618 by araujo:
Fix a warning spotted by gcc4.9: dereferencing type-punned pointer will break
strict-aliasing rules.

Declare some variables as statics as well as some functions that are internal
helpers. Update the function broadcast_result() to a post-K&R definition.

285617 by ache:
Comment out usr/sbin/mailwrapper removal
because for no mailwrapper case we have:
/usr/sbin/sendmail -> /usr/sbin/mailwrapper
/usr/sbin/mailwrapper -> /usr/libexec/sendmail/sendmail
Add comment explaining it.
