This used to refer to x87 support for x86 machines.
npx isn't really a driver any more. we don't support x86 hardware
without an FPU, and we don't call it by that name in the code or
attach it as npx at something.
brought up on tech-kern. unfortunately the copy to port-i386 disappeared
in a spam filter.
The former allows the ncurses (and pdcurses) macros getsyx and setsyx
to be implemented, which is needed by a surprising number of applications.
The latter is needed for Python curses support so it doesn't have to dive
into ncurses window structure.
7265 works fine.
7260 and 3160 maybe work.
7265D, 3165 and 8260 not work yet.
if_iwm.c: r1.147.
if_iwmreg.h: r1.19 without r1.16.
if_iwmvar.h: r1.24.

Add new ptrace(2) calls:
- PT_COUNT_WATCHPOINTS - count the number of available hardware watchpoints
- PT_READ_WATCHPOINT - read struct ptrace_watchpoint from the kernel state
- PT_WRITE_WATCHPOINT - write new struct ptrace_watchpoint state, this
includes enabling and disabling watchpoints
The ptrace_watchpoint structure contains MI and MD parts:
typedef struct ptrace_watchpoint {
int pw_index; /* HW Watchpoint ID (count from 0) */
lwpid_t pw_lwpid; /* LWP described */
struct mdpw pw_md; /* MD fields */
} ptrace_watchpoint_t;
For example amd64 defines MD as follows:
struct mdpw {
void *md_address;
int md_condition;
int md_length;
};
These calls are protected with the __HAVE_PTRACE_WATCHPOINTS guard.
Tested on amd64, initial support added for i386 and XEN.

Note that entries in the md.i386 and md.amd64 lists are actually deleted
(rather than being marked "obsolete" as directed in the comments). This
is OK, since there is now a new module in the mi list to replace them.
