139cdc3125 Make nbuf, nswbuf, and bufpages unsigned. Make all operations on these 
variables unsigned, and update places where their values are printed.

88d1869bb4 No need for two copies of the i8253 register definitions. Remove the 
i386-specific copy, and adjust its users to add in the timer i/o base
as necessary.

3912e469dd Rename cdev_systrace_init() to cdev_clonemisc_init(), so it can 
be properly used by any misc. cloning device.  While here, correct
a comment to indicate that "open" is the only entry point and that
everything else is handled with fileops.

e539a84832 Since the return address is now part of struct sigframe, adjust the stack

011d4d5f44 Add kernel support for having userland provide the signal trampoline: 
* struct sigacts gets a new sigact_sigdesc structure, which has the
  sigaction and the trampoline/version.  Version 0 means "legacy kernel
  provided trampoline".  Other versions are coordinated with machine-
  dependent code in libc.
* sigaction1() grows two more arguments -- the trampoline pointer and
  the trampoline version.
* A new __sigaction_sigtramp() system call is provided to register a
  trampoline along with a signal handler.
* The handler is no longer passed to sensig() functions.  Instead,
  sendsig() looks up the handler by peeking in the sigacts for the
  process getting the signal (since it has to look in there for the
  trampoline anyway).
* Native sendsig() functions now select the appropriate trampoline and
  its arguments based on the trampoline version in the sigacts.

Changes to libc to use the new facility will be checked in later.  Kernel
version not bumped; we will ride the 1.6C bump made recently.
