fc181f91c6 use EMUL_GETPID_PASS_PPID or EMUL_GETID_PASS_EID to find out if one should 
pass parent pid for getpid() or effective id for get[ug]id(), instead
of compile-time dependency

30760da04a no need to define emul_osf1, <compat/osf1/osf1_exec.h> defines it for us now

01040d97a2 add e_path (emulation path) to struct emul, which replaces emulation-specific 
*_emul_path variables

change macros CHECK_ALT_{CREAT|EXIST} to use that, 'root' doesn't need
to be passed explicitly any more and *_CHECK_ALT_{CREAT|EXIST} are removed
change explicit emul_find() calls in probe functions to get the emulation
path from the checked exec switch entry's emulation

remove no longer needed header files

add e_flags and e_syscall to struct emul; these are unsed and empty for now

7d3a48b31d recognize ^if and ^endif in input master syscall file specially - output it 
like #if and #endif to sysdcl; this can be used to insert ifdefs
to generated *sysent.c

10571faa84 Introduce uvm_km_valloc_align() and use it to glab process's USPACE 
aligned on USPACE boundary in kernel virutal address.  It's benefitial
for MIPS R4000's paired TLB entry design.

3c9d9276dc Add new powerhook argument values, PWR_SOFTSUSPEND, PWR_SOFTSTANDBY and 
PWR_SOFTRESUME. Apm calls powerhook with the values in normal interrupt
priority level while others are protected with splhigh().

d9a0883770 define COMPAT_OLDSOCK unconditionally - the code is used virtually for all 
emulations besides NetBSD, and this way it's LKM-safe

fa19fe52db adjust the spinlock macros in the non-MULTIPROCESSOR, non-LOCKDEBUG case 
so that gcc will think that static spinlock are used.
this allows us to remove the ugly conditionalization of
static spinlock declarations.

baae0324b9 restructure struct emul and execsw, in preparation to make emulations LKMable: 
* move all exec-type specific information from struct emul to execsw[] and
  provide single struct emul per emulation
* elf:
  - kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry
    per emulation and contains pointer to respective probe function
  - interp is allocated via MALLOC() rather than on stack
  - elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
  to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
  emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
  part of appropriate execsw[] entry
* constify couple of structures

3075dec01a Allow machine dependent code to specify a hook to be run when a 
spinlock's interlock is released.

a174b8a595 simple_lock_held is only defined when you use LOCKDEBUG. 
Put it for now in an ifdef LOCKDEBUG.

f104ee65be Add a sysctl_rdminstruct() function - same as sysctl_rdstruct() but 
can return short data if *oldlenp is less than len.

26fe6166ed check_pty(): simple_unlock() might have been called even if the lock was 
not locked previously in some cases; unlock only if the lock is held

f276315e1c In pool_setlowat(), only call pool_catchup() if the pool is under the 
low water mark.  (Avoids annoying warning when you setlowat a static
pool).

68f0fe3840 make sure every m_aux will be freed. 
there are direct use of MFREE() from sys/kern.
(we experienced no memory leak so far, but if we use m_aux for other purposes,
we will need this change)

a284236c04 in fork1(), only add make the new proc visible (by giving it a pid 
and adding it to allproc) after it's fully initialized.
this prevents the scheduler from coming in via a clock interrupt
and tripping over a partially-initialized proc.
