0175db6e40 #ifdef KTRACE some stuff. 2000-12-12 03:33:16 +00:00

9c25e9208a Port 'an' driver for Aironet PC4500/PC4800 IEEE802.11 card from FreeBSD. 
This is very adhoc work for IETF meeting.
- Since it seems that 'an' and 'wi' have similar hardware, low level
  functions should be shared.
- There are PCI/ISA cards of Aironet but not supported yet.
- The wiconfig interface is changed so that wiconfig cannot be used.
- 'ancontrol' of FreeBSD is not ported.
- Only infrastructure mode is tested.
- WEP is not supported.

Though I only have an Aironet card, Cisco card should be expected to work.

9a8fbe25bc Handle the VM86-mode syscall problem by changing the syscall vector when 
jumping in or out of VM86 mode.

1ef2795be9 Separate the syscall handlers into two versions -- one which does ktrace, and 
one which doesn't.  Dynamically switch.
There's more to do on this, but I have to go to work.

f495cd9dc6 Introduce 2 new flags in types.h: 
* __HAVE_SYSCALL_INTERN.  If this is defined, e_syscall is replaced by
  e_syscall_intern, which is called at key places in the kernel.  This can be
  used to set a MD syscall handler pointer.  This obsoletes and replaces the
  *_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL.  If this is defined, certain (deprecated) elements in
  struct emul are omitted.

66610a4779 Introduce PROC_PC(), which is used to get a process's user PC. If this is 
defined, call addupc_intr() directly from statclock() in the system time case,
using the same P_OWEUPC path if the copyin/copyout fails.
Use this in i386 to remove profiling code from the normal userret() path.

8ca533ee5b since this is now standalone and not called via syscall(), we need to 
update statistics and set p->p_md.md_regs accordingly here

44d7fef20a make locore.s call emulation-specific syscall code directly 
this should improve speed of emulation syscall path (avoids one function call,
and emulations syscall can use the trapframe trick)

afc49e36eb Set md_regs before call the alternate syscall handler. 
Remove the EMUL_HAS_SYS___syscall test, because the handler is no longer shared
with SVR4.
Rather than comparing with e_nsysent, just mask the value.  This is only done
to protect us from malicious programs anyway.

57fdd67be5 Do the resched check *only* on an AST. 
Also, there is no reason to save the original PC; there are no restartable
syscalls that change the PC -- and even if there were, they wouldn't do it
in the restart case.
