Redefine evil tXXX register offset defines into the trapframe structure

In i386_softintr_lock(), use splserial() rather than splhigh(),

Use global descriptor 7 for mach traps. Unfortunately this is already

used by apm 16 bit code segments so we cannot have both at the same time.

Add COMPAT_MACH and EXEC_MACHO. Code works enough to start running a binary,

but we need to implement a few mach traps before the dynamic linker actually
works.

Add a linux specific trapsignal() function. This is just a passthrough
...
on all platforms but the i386. On the i386 we look at T_PROTFLT and send
a SIGSEGV instead of SIGBUS. This makes allegro lisp 5.0 and pvs (a proof
verification system) to work.
XXX[1]: We need to go through each architecture and verify that we send
the correct signal on each trap type.
XXX[2]: trap.c on all other architectures but i386 needs to be modified
to s/trapsignal/(*p->p_emul->e_trapsignal)/g
2001-06-18 02:04:42 +00:00

Add %fs/%gs to trap frame and save/restore them on
...
trap/interrupt/syscall entry from userspace.
Remove special-case "by hand" validation of fs/gs register values as
well as special handling of them in various signal handling paths.
Now, like %ds and %es, they are validated by the hardware on return to
userland.
This paves the way for the use of %fs for per-cpu data on
multiprocessor systems, and fixes an otherwise difficult-to-fix
interaction between threads/clone(2) and USER_LDT.
Discussed in advance with Frank van der Linden.

For ports that wire up pciide in compatibility mode, have
...
them define __HAVE_PCIIDE_MACHDEP_COMPAT_INTR_ESTABLISH
in pci_machdep.h and pciide_map_compat_intr() only calls
pciide_machdep_compat_intr_establish() if that preprocessor
define exists.
Ports that don't need to do this no longer need to supply a
dummy function.
