change inst_symlink to inst for insmod
...
Use "inst" instead of "inst_symlink" for insmod, since insmod might not
necessarily be a symlink on some distros. inst_symlink is functionally
the same as inst, with an additional check to make sure that it's a
symlink (which we don't care about either way).

fix dracut dependencies
...
The "kpatch install" command is broken because the kpatch script has
some missing dependencies in the initramfs. Make sure the new
dependencies (readelf and awk) are added to the initramfs.

kernel crash.
Add rcu_barrier() to kpatch_exit() to wait for all outstanding

warn detection fix

The current WARN detection logic catches the majority of cases, but
there are still a lot of outliers which it doesn't catch (thanks, gcc).
I looked at a much larger sample of WARN calls and came up with a more
generic algorithm.

make _rs a special static local
...
The _rs variable is used for printk ratelimiting, similar to __warned,
which makes it a logical candidate to be "special": don't correlate it,
yet don't mark a function as changed just because it references it.

allow patched modules to call external functions

When patching a kernel module, if we can't find a needed dynrela symbol,
we currently assume it's exported. However, it's also possible that
it's provided by another .o in the patch module. Add support for that.

Currently unbundled section references are only replaced if the start of
the symbol is referenced. It's also useful to support replacement of
references which point to inside the symbol.
