Break libxkb into two separate libraries (libxkb and libxbkstubs). Pull
in libxkbstubs for Xvfb and Xnest, and for Xorg use dixmods/libxorgxkb.
Now Xorg no longer uses the stub XkbDDXSwitchScreen from xkb/ddxVT.c so
display switching works again.
Note that any of "${}()" in variable names will be griefsome!
Remove the example of using ::= to apply a modifier to a .for loop
variable as that is no longer necessary.
Remember to change the date :-)
Instead of doing a full substitution giving plain text, just replace the
variable part with something that will expand to the required text - leaving
any modifiers for the later evaluation of the input line.
This stops .for being used as an 'eval' (previously you could generate .if etc)
and also means it is still a variable expansion - which some other parts need
to work in the expected fashion.
This does not realy change anything in the crunched version, but helps
debugging foreign languages and will magically start working once we
un-castrate locales in the crunched environment.
parts of make that try to scan through variable expansions.
(given the make syntax that is all rather doomed anyway!)
Move the check for $\0 to a place where it will be detected - otherwise
the parser will run off the input buffer!
-It can be enabled by tweaking kern.sched.kpreempt_pri sysctl.
+On architectures where kernel preemption is not supported natively, these
+functions may still be used.
- It doesn't work and a dead system that can't be reset from the console is
worse than a system that has painced and rebooted. If you can make it work
reliably please do so.
- If the system is paniced there is every reason to suspect VM structures
and the contents of the buffer cache.
while ironically trying to preserve the same during copy. Would only have
occurred if a multithreaded program expanded the descriptor table and,
within a tiny window of exposure, another thread in the program tried to
access descriptor zero.
- Convert to use kmem_alloc/kmem_free.
