fe8cdcae87 - Replace inline implementations of sigprocmask() with calls to
kern_sigprocmask() in the various binary compatibility emulators.
- Replace calls to sigsuspend(), sigaltstack(), sigaction(), and
  sigprocmask() that used the stackgap with calls to the corresponding
  kern_sig*() functions instead without using the stackgap.

43cf129c99 Sync up linux and svr compat elf fixup functions for exec(). These
functions are now all basically identical except that alpha linux uses
Elf64 arguments and svr4 and i386 linux use Elf32.  The fixups include
changing the first argument to be a register_t ** to match the prototype
for fixup functions, asserting that the process in the image_params struct
is always curproc and removing unnecessary locking to read credentials as a
result, and a few style fixes.

1822cdcafe It seems I accidently committed a change that removed the userland includes
from the kernel build.  This broke linux_genassym on the alpha.  For the
kernel, the correct place to get offsetof() is not in /usr/include/stddef.h
but rather <sys/types.h>

3ebc124838 Infrastructure tweaks to allow having both an Elf32 and an Elf64 executable
handler in the kernel at the same time.  Also, allow for the
exec_new_vmspace() code to build a different sized vmspace depending on
the executable environment.  This is a big help for execing i386 binaries
on ia64.   The ELF exec code grows the ability to map partial pages when
there is a page size difference, eg: emulating 4K pages on 8K or 16K
hardware pages.

Flesh out the i386 emulation support for ia64.  At this point, the only
binary that I know of that fails is cvsup, because the cvsup runtime
tries to execute code in pages not marked executable.

Obtained from:  dfr (mostly, many tweaks from me).

this is a low-functionality change that changes the kernel to access the main

e4383d97be Stop using linux_getpgid(). The implementation at this time is

While here, redefine the second entry for setpgid() so that we
don't need a stub. This is achieved by giving the second instance

5002a60f9b Round of cleanups and enhancements. These include (in random order):
o  Introduce private types for use in linux syscalls for two reasons:
   1. establish type independence for ease in porting and,
   2. provide a visual queue as to which syscalls have proper
      prototypes to further cleanup the i386/alpha split.
   Linuxulator types are prefixed by 'l_'. void and char have not
   been "virtualized".

o  Provide dummy functions for all syscalls and remove dummy functions
   or implementations of truely obsolete syscalls.

o  Sanitize the shm*, sem* and msg* syscalls.

o  Make a first attempt to implement the linux_sysctl syscall. At this
   time it only returns one MIB (KERN_VERSION), but most importantly,
   it tells us when we need to add additional sysctls :-)

o  Bump the kenel version up to 2.4.2 (this is not the same as the
   KERN_VERSION MIB, BTW).

o  Implement new syscalls, of which most are specific to i386. Our
   syscall table is now up to date with Linux 2.4.2. Some highlights:
   -  Implement the 32-bit uid_t and gid_t bases syscalls.
   -  Implement a couple of 64-bit file size/offset bases syscalls.

o  Fix or improve numerous syscalls and prototypes.

o  Reduce style(9) violations while I'm here. Especially indentation
   inconsistencies within the same file are addressed. Re-indenting
   did not obfuscate actual changes to the extend that it could not
   be combined.

NOTE: I spend some time testing these changes and found that if there
      were regressions, they were not caused by these changes AFAICT.
      It was observed that installing a RH 7.1 runtime environment
      did make matters worse. Hangs and/or reboots have been observed
      with and without these changes, so when it failed to make life
      better in cases it doesn't look like it made it worse.

652f47436e o Introduce private types for use in linux syscalls for two reasons:
1. establish type independence for ease in porting and,
   2. provide a visual queue as to which syscalls have proper
      prototypes to further cleanup the i386/alpha split.
   Linuxulator types are prefixed by 'l_'. void and char have not
   been "virtualized".

o  Provide dummy functions for all unimplemented syscalls, except for
   the osf1 syscalls. This can only be done if the osfulator
   implements at least all syscalls used by the linuxulator. Remove
   dummy functions for syscalls that are now truely unimplemented.

o  Set the syscall namespace as follows: Mark a syscall as OSF1 if
   the Linux kernel has prefixed the syscall with 'osf_' and has
   provided special implementations for it. Otherwise mark the
   syscall as LINUX by default. Some of the LINUX syscalls remain
   marked as BSD or POSIX.

o  Rename syscalls so they match the names used in the Linux kernel.
   Also, provide more accurate prototypes. This generally improves
   cross-referencing and reduces head-scratching.

o  Fix the (g|s)etresuid syscalls. They mapped to (g|s)etresgid.

o  Sanitize the the shm*, sem* and msg* syscalls. Their prototypes
   were dictated by the way these syscalls were used in the i386
   code. That has been fixed. NOTE: linux_semctl now passes it's
   'arg' parameter by value and not by reference.

o  Fix prototype of linux_utime. It takes a struct timeval, not a
   struct utimbuf.

o  Fix the linux_sysfs syscall. It's index is not 255, but 254.

o  Implement the following syscalls:
     linux_sysctl

o  Add the following new syscalls:
     (g|s)etresgid
     linux_pivot_root (dummy)
     linux_mincore (dummy)
     linux_pciconfig_iobase (dummy)
     linux_getdents64

f41325db5f With this commit, I hereby pronounce gensetdefs past its use-by date.
Replace the a.out emulation of 'struct linker_set' with something
a little more flexible.  <sys/linker_set.h> now provides macros for
accessing elements and completely hides the implementation.

The linker_set.h macros have been on the back burner in various
forms since 1998 and has ideas and code from Mike Smith (SET_FOREACH()),
John Polstra (ELF clue) and myself (cleaned up API and the conversion
of the rest of the kernel to use it).

The macros declare a strongly typed set.  They return elements with the
type that you declare the set with, rather than a generic void *.

For ELF, we use the magic ld symbols (__start_<setname> and
__stop_<setname>).  Thanks to Richard Henderson <rth@redhat.com> for the
trick about how to force ld to provide them for kld's.

For a.out, we use the old linker_set struct.

NOTE: the item lists are no longer null terminated.  This is why
the code impact is high in certain areas.

The runtime linker has a new method to find the linker set
boundaries depending on which backend format is in use.

linker sets are still module/kld unfriendly and should never be used
for anything that may be modular one day.
