   4 Subject: [PATCH] lib/gen_tables.c: define EHWPOISON when not available
   5
   6 When building on some old system with old kernel headers, the
   7 gen_tables.c program (built natively) doesn't build due to missing
   8 EHWPOISON. This commit defines EHWPOISON to the value found in
   9 asm-generic kernel headers, which is correct for most (but not all
  10 architectures).
  11
  12 Anyway, the whole concept of building a program on the host to generate
  13 a table with errno values, then built into a target program is
  14 inherently broken, so our fix is not more broken than the rest of the
  15 mechanism used by audit.
