Use linux_emul_convpath() rather than linux_emul_find() as

linux_emul_find() is going away.

When running Linux binaries, set up the initial FPU state as Linux

o Split out kernel part of execve(2) syscall into two parts: one that

2005-01-29T23:12:00+00:00

  copies arguments into the kernel space and one that operates
  completely in the kernel space;

o use kernel-only version of execve(2) to kill another stackgap in
  linuxlator/i386.

Axe the semblance of support for PECOFF and Linux a.out core dumps.

2004-11-27T06:46:45+00:00

Maintain the broken state of backwards compatibilty for a.out (and

2004-11-20T02:32:04+00:00

PECOFF!) core dumps.  None of the old versions of gdb I tried were
able to read a.out core dumps before or after this change.

Do a pass over all modules in the kernel and make them return EOPNOTSUPP

for unknown events.

A number of modules return EINVAL in this instance, and I have left
those alone for now and instead taught MOD_QUIESCE to accept this
as "didn't do anything".

Change the types of vn_rdwr_inchunks()'s len and aresid arguments to

This is a better fix for overflows that occurred when dumping segments
larger than 2GB to core files.

Make sigaltstack as per-threaded, because per-process sigaltstack state

2004-01-03T23:31:29+00:00

is useless for threaded programs, multiple threads can not share same
stack.
The alternative signal stack is private for thread, no lock is needed,
the orignal P_ALTSTACK is now moved into td_pflags and renamed to
TDP_ALTSTACK.
For single thread or Linux clone() based threaded program, there is no
semantic changed, because those programs only have one kernel thread
in every process.
