pk 87d5e88b94 sun4/sun4 mem_fault(): on kernel faults we now need to try to page in a 
a `pmeg' too. See also sparc/pmap.c, rev 1.265.

pk 98d3a23993 Extensive rewrite of the sun4/sun4c pmap code to allow non-wired kernel 
mappings to use the pre-emptable pool of `PMEG' MMU resources.

scw 8d5dbf5382 An FPUEXC leaves the PC pointing to the FP instruction 
which caused the exception. To avoid an endless loop if
the user is ignoring or catching SIGFPE, adjust the saved
PC to skip over the offending instruction.

tls 062dab3c81 Remove RND_FLAG_NO_ESTIMATE and comment claiming we can't estimate (which 
means "count", in this context) the entropy we're adding because we poll the
device periodically.  Sure, we poll it periodically, but it's a hardware
RNG -- the data returned should be random no matter when we read the
register!

skrll d900731978 Resolve dlsym(3) and friends directly so that dlsym(RTLD_NEXT,...) works. 
Previously dlsym resolved to the version in crt0.o or libc which would
mean that the caller's shared object couldn't be determined correctly
using __builtin_return_address(0).

Mainly from FreeBSD, but adapted by me. Benefits of this solutions are:

	- backward comptibility maintained
	- existing broken binaries are fixed with a new ld.elf_so
	- __mainprog_obj can be removed from crt0.o
	- we do the same thing as FreeBSD

Fixes PR 22067.

OKed by Jason and Christos.

fvdl 8655b27bf5 SA fixes from Stephan Uphoff. Quoting him: 
The patch below (hopefully) improves some signaling problems
found by Nathan.

It also contains some cleanup of the sa_upcall_userret() function
removing any sleep calls using PCATCH.

Unblocked threads now only use an upcall stack after they
acquire the virtual CPU.
This prevents unblocked threads from stealing all available
upcall stacks.


Tested by Nick Hudson.

drochner e8d0979bed Fix stack location for VM86 processes in the !sigaltstack case. 
I doubt it makes much sense to use the VM's stack for this, but the
old code was doubtless wrong because it potentially overwrote random
user memory.
(It might be a good idea to use the process' pre-vm86()-call stack,
but atm the infrastructure for this is missing.)
