may not be implemented by the processor and a Speculative Operation
fault is raised. The OS is responsible to emulate the branch.
Implement this, because GCC 4.2 uses advanced loads regularly.

Visual inspection of the surrounding code indicates that the code does
what it's supposed to do; i.e., the pointless code wasn't supposed to
be doing something other than what it was doing.

scheduler lock is not involved. sched_lock still protects the sched_clock
call. Another patch will remedy this.

- Replace a magic 14 with the newly added IDC_ITID_SHIFT macro.
- Remove the global mp_boot_mid variable as it's not really necessary
and just replacing it with PCPU_GET(mid) doesn't have any impact on
performance once booted.
- Replace PCPU_GET(cpuid) with the curcpu shortcut.
- Replace hardcoded function names in panic strings etc with __func__
so they don't need to be updated when renaming the function.
- Use register_t instead of u_long for variables used to hold the
return value of intr_disable() so we don't need to apply any
knowledge about the actual width of that value here.
- Improve the wording of some comments.
- Fix several style(9) bugs.
- Use __FBSDID in identcpu.c.
- Remove #ifndef SUN4V around global cpu_impl variable; it doesn't
hurt on sun4v for now and once setPQL2() is gone sun4v can stop
sharing identcpu.c with sparc64, making the reminder of this file
also sparc64-only again. [1]

in the sun4v source in order to be able to compile the source which
is shared between sparc64 and sun4v just #include the sparc64
version here instead of duplicating it.
This is based on the approach taken by pc98 headers in order to
compile the source shared between i386 and pc98.
iommureg.h (which already began to bitrot) and iommuvar.h from the
sun4v source and adjust some of the source which is shared between
sparc64 and sun4v as appropriate.

This is only for the well known known ports (port 1-1023) for tcp and
udp only.
Changes:
- Removed "problems" comments around port 57, 77 and 87
- Removed audionews (port 114)
- Added imap3 (port 220)
- Removed yak-chat (port 258)
- Removed concert (port 786)
- Added a lot of new allocations

ignore the size of any headers that were passed with the sendfile(2)
system call. Otherwise the file sent will be truncated by the header
size if the nbytes parameter was provided. The bug doesn't show up
when either nbytes is zero, meaning send the whole file, or no header
iovec is provided.
Resolve a potential error aliasing of errors from the VM and sf_buf
parts and the protocol send parts where an error of the latter over-
writes one of the former.
Update comments.
The byte accounting bug wasn't seen in earlier because none of the popular
sendfile(2) consumers, Apache, lighttpd and our ftpd(8) use it in modes
that trigger it. The varnish HTTP proxy makes full use of it and exposed
the problem.

into the vendor branch since this is already in the csup repository.
