Tony Finch d8379ab1dd unifdef: update to upstream revision 1.190
Fix handling of input files (e.g. with no newline at EOF) that could
make unifdef get into an unexpected state and call abort().

The new -B option compresses blank lines around a deleted section
so that blank lines around "paragraphs" of code don't get doubled.

The evaluator can now handle macros with arguments, and unbracketed
arguments to the "defined" operator.

Add myself to MAINTAINERS for unifdef.

Russell King eedc9d83ea kbuild: fix headers_exports with boolean expression
When we had code like this in a header unifdef failed to
deduct that the expression was always false - and we had code exported
that was not intended for userspace.

#if defined(__KERNEL__) && !defined(__ASSEMBLY__)
  int a;
#endif

This commit implment support in unidef which allows it to work out if
an #if expression always evaluates true or false for symbols which
are being undefined/always defined.

The patch is slightly more complicated than I'd hoped because unifdef
needs to see lines fully evaluated - doing otherwise causes it to
mark the line as "dirty" and copy it over no matter what.

Sam Ravnborg 01f1c8799a kbuild: add unifdef
This patch contains a raw copy of unifdef.c
Next patch will modify it and add infrastructure to use it
Adding unifdef to the kernel is acked by the author.

The reason to add unifdef as part of the kernel source is that it is not
yet a common utility on most distributions.
