d5ed80d9c6 The IRIX usinit(3) function expects a page of memory to be available at 
address 0x200000 (disasembling usinit shows that this address is hardcoded in
libc). It uses it for locks and semaphres.

We therefore allocate this page of memory, to prevent IRIX process from
faulting when thay call usinit(3).

f8c12b3107 IRIX provide a signal trampoline in libc, we now use it. 
- the signal trampoline address is given to the kernel by a sigaction()
  fourth argument
- we introduce an irix_emuldata structure to keep track of the signal
  trampoline address
- we don't support per-sigaction signal trampolines, we only do per-process
- now that we use the IRIX libc signal trampoline, we do not have to handle
  the errno update from the signal trampoline
- it is possible that IRIX 5 signal delivery works too, since theses binaries
  will come with their own signal trampoline

5ee554064d Reworked IRIX signal delivery so that ucontext is used instead of sigcontext 
when SA_SIGINFO is used. The IRIX process will hence find the expected
information using the third argument of the signal handler.

We do not provide code and siginfo yet.

78583a4567 Always define SA_SIGINFO, and keep track of it in SVR4 emulation. This is 
needed for IRIX signal delivery.

2dd126f08e Fixed the swap block size problem: the swap block size as used in struct 
swapent, or as seen in userland, is dbtob(1), which turns to be 512 for all
arch for now.

In struct swapdev, there is another field for block size. This value is private
to uvm_swap.c and is only used for swap I/O on regular files. It is equal to
the underlying device block size and it is not necessarily 512.

0b5e2aba9a Fix problem with assumption non-socket == vnode in F_{G,S}ETOWN different way 
(revisions 1.47 & 1.48 effectively backed off):
* for all but vnodes, just fallback to sys_fcntl(); assumming
  state of support for F_SETOWN/F_GETOWN and even hardcoding it here is
  not right (e.g. rev. 1.47 had this incorrect for DTYPE_PIPE)
* fallback to sys_fcntl() also for vnodes which don't represent tty
* don't need to use FILE_{,UN}USE() here, the code won't block while
  using the pointer

89e46d8a99 Reworked the o32/n32 matching scheme. IRIX uses some e_flags in the ELF 
header to distinguish between o32, n32 and n64 ABIs. We now use this.
This suppress the need of the mips_option test, which had some fake positive.
This also removes the mandatory ordering of n32 vs o32 in the exec switch
(exec_conf.c)

e52b5e4bfb Resolve alpha compile issues: 
- bug with order in args in mask conversion md code.
- flags can be both int and long on the alpha. kludge around that, by not
  passing pointers to the conversion function.
- something is wrong with the toolchain look at the void * cast in copyout().
- sa_restorer is in a different place on the aplha. Deal with that, by not
  initializing it as before. XXX: this should be changed in the MD signal
  definition.

d383f72720 reworked signal handling: 
- do not save/and restore registers that should not be saved and restore
- do give an accurate sigcontext pointer to the signal handler
- do use the struct sigreturna from IRIX.
This eliminates panics and hangs in certain circonstances

Also some cosmetic changes with tabs usage
