scripts: fix gfp-translate after ___GFP_*_BITS conversion to an enum
[ Upstream commit a3f6a89c834a4cba0f881da21307b26de3796133 ]
Richard reports that since 772dd0342727c ("mm: enumerate all gfp flags"),
gfp-translate is broken, as the bit numbers are implicit, leaving the
shell script unable to extract them. Even more, some bits are now at a
variable location, making it double extra hard to parse using a simple
shell script.
Use a brute-force approach to the problem by generating a small C stub
that will use the enum to dump the interesting bits.
As an added bonus, we are now able to identify invalid bits for a given
configuration. As an added drawback, we cannot parse include files that
predate this change anymore. Tough luck.
