Subjectcompiling ppp-2.2.0f with linux-pre2.0.1{01}
There was a recent thread about how pre2.0.10 wouldn't allow
ppp-2.2.0f to compile. It seems to me that this is a problem with the
headers in that kernel.

linux-pre2.0.11 hasn't fixed it, although the error is different:

[/usr/src/ppp-2.2.0f]% mv pppd/sys-linux.c pppd/sys-linux.c-patched
[/usr/src/ppp-2.2.0f]% mv pppd/sys-linux.c.orig pppd/sys-linux.c
[/usr/src/ppp-2.2.0f]% make

asmlinkage void do_bottom_half(void);

Adding this line to ppp-2.2.0f/pppd/sys-linux.c seems to fix the
problem (like it did with 1.99.10):

#include <linux/sched.h>

Interestingly, adding the SAME line to linux-1.99.11/include/linux/interrupt.h
instead, ALSO works!

Question is... what is the _real_ fix?
