36d40de856 For now, probably forever, prohibit unquoted $ and ` in the names of 
functions being defined (they can still be included if quoted).

If we parsed the way POSIX specifies (leaving the exact input text of
$ and ` expansions unaltered, until required to be expanded) this would
not be needed, as the name of a function being defined does not underbo
parameter, command, or arith expansions, so xxx$3() { : ; } would just
work.   But for many reasons we don't do that (and are unlikely to ever,
though maintaing both forms might be an option someday) - which led to
very obscure behaviour (if sh were compiled in DEBUG mode, even an abort())
and certainly nothing useful.   So just prohibit these uses for now.
(A portable function name must be a "name" so this makes no difference
at all to posix compat applications/scripts).

A doc update is pending (the updated sh.1 also contains updates in other
areas not yet appropriate to commit).

a8aa7072a7 in uao_get(), if we unlock the uobj to read a page from swap, 
we must clear the cached page array because it is now stale.
also add a missing call to uvm_page_array_fini() if the I/O fails.
fixes PR 55493.

dd79f1e46f Make sure pmap_kenter_pa(9) handles uncached mappings properly. 
Fixes "cgfour(4) is mis-probed as bwtwo(4)" problem on 3/80
that has been broken since NetBSD 1.6.
Now Xorg 1.20 based Xsun 8bpp color server is confirmed working
on the cgfour(4).

Should be pulled up to netbsd-9.

XXX: all MD PMAP_NC flags should be replaced with MI PMAP_NOCACHE flag.

daaf9b06cf We don't need to call the POW and FGA bootstrap functions from the FDT

d117c8147b Operation union_readdirhook() stores the lower directory as un_uppervp. 
This breaks the assumption that un_uppervp->v_mount is the upper mount.

Fix by storing the directory as un_lowervp and adapt union_readdir().

Should fix PR kern/55552: panic with union mount
