this should improve speed of emulation syscall path (avoids one function call,
and emulations syscall can use the trapframe trick)
Idea: Charles Hannum
quite simply a question of the Qlogic being little endian and having
to have stuff swapped on big endian machines- it also has to do with the
fact that the SBus and PCI DMA layouts are wierd with respect to this.
At any rate, now finally fixed- works on Mac G4, tested it on a SS10
for sparc, checked on alpha to see if I've broken anything, and as
soon as I get another spare afternoon I'll finally install a sparc64
version which should just work (as it'll be like the Mac).
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.
* Make the syscallnames[] table const.
* Add a separator between the #include section and the syscalls section, so
that #if/#else/#endif can be handled differently in the two.
* Add support for rounding up the size of the sysent table.
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.
mandatory for IPv6 (so we can't just validate by using connected pcb - we need
to allow traffic from unconnected pcb to do pmtud).
- if the traffic is validated by xx_ctlinput, allow up to "hiwat" pmtud
route entries.
- if the traffic was not validated by xx_ctlinput, allow up to "lowat" pmtud
route entries (there's upper limit, so bad guys cannot blow up our routing
table).
