Commit a893ea15d764 ("tpm: move tpm_chip definition to
include/linux/tpm.h") introduced a build error when both ima and efi is
enabled. What happens is that both headers (ima.h and efi.h) defines the
same 'NONE' constant, and it broke when they started getting included
from the same file.

  NONE,

Rework to prefix the ima enum with 'IMA_*'.

Ok, this looks reasonable, but will have a minor clash with Gustavo's
"security: mark expected switch fall-throughs and add a missing
break".

James, are you picking up Gastavo's v2 patch from Friday?

This patch correctly didn't modify the IMA policy keywords, just the
enumeration, but now the <securityfs> policy file incorrectly displays
the "ima_" prefixed names.

Instead of maintaining an enumeration and the corresponding
stringified version of the enumeration, there is a single list with
two macros.  One of these macros needs to be modified.  Instead of
modifying the the hook names directly, I would probably modify the
enumeration macro.

#define __ima_hook_enumify(ENUM)        ENUM,

enum ima_hooks {
        __ima_hooks(__ima_hook_enumify)
};

and

#define __ima_hook_stringify(str)       (#str),

static const char *const func_tokens[] = {
        __ima_hooks(__ima_hook_stringify)
};
