80eef17ba9 o Remove vm_map_growstack() and useracc() from sendsig(). Copyout() and 
suword() will automatically grow the stack if needed.
 o Add a comment that osigreturn() and sigreturn() are MPSAFE.

de67a4bd91 Back out the last revision - it does not work correctly when one of 
the pages in question is not in the top-level vm object, but in
one of the shadow ones.

6871a6c89e Rework ptrace(2) to be more locking friendly. We do any needed copyin()'s 
and acquire the proctree_lock if needed first.  Then we lock the process
if necessary and fiddle with it as appropriate.  Finally we drop locks and
do any needed copyout's.  This greatly simplifies the locking.

60f2606a7d Do not use pmap_kextract() to find out the physical address of a user 
belong to a user virtual address; while this happens to work on some
architectures, it can't on sparc64, since user and kernel virtual
address spaces overlap there (the distinction between them is done via
separate address space identifiers).

Instead, look up the page in the vm_map of the process in question.

c85c7b5ff6 Print extra information in printtrap() if the interrupted state was for

normally going to be useful (e.g. pointers need to be zero extended).

9ca98629d7 Fix definition of va_start: We don't need to take the address of 
va_list. It's a builtin type. gcc 3.1 doesn't care either way,
but gcc 3.2 is more picky and doesn't like the former.

a8f559e910 Really fix uniprocessor on IA64. Note to self: do not use variables before 
they are initialized.   I had correctly figured out that the UP problem was
the pcpu current_pmap thing, but didn't fix it right last time.

e122b676e6 Replace the original host WEP implementation with the one in OpenBSD 
(apparently by markus@, at least committed by him).  This has the
advantage of not using the bad IV's from Fluhrer/Mantin/Shamir as well
as bringing the drivers a little closer together.

Also use a few constants in place of magic numbers in one place.

b2f485ca0d Delay umass_cam_rescan by 200 ms to make sure attach is finished by the 
time we tell CAM to rescan the bus. Together with the previous patch
this should avoid the problem where the devices would wedge because they
got spoken to over two different pipes.

31c41f1b1e Bandaid for a buffer overrun in the module searching code. When breaking 
up the module_path string, we would walk one past the end of the buffer.
This hurting ia64 originally, but it was probably also happening on i386
occasionally as well.  The effects were usually harmless, it would add
bogus "binary" search directories to the places it actually looked for
files.

2ab188f529 Finally fix loader completely for IA64. efifs_stat() wasn't setting 
the S_IFREG bit for regular files.  This caused the path search code to
skip it when it finally did find the kernel (after the common/module.c
buffer overrun bug was fixed)

1bd2b5b4cd Integrate the hostap stuff that Thomas Skibo <skibo@packbell.net> 
wrote.  This code was for 4.5-release, so I've ported it to -current
and made a few minor tweaks.  The biggest non-style tweak was to not
make access point the default.

More changes will be needed to get this actually working, but I wanted
to get a relatively pure baseline.  This doesn't seem to break what
works now.
