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