#1174407 — 4.2-rc0: akcipher breaks compilation

Hi!

CC      crypto/akcipher.o
    CC      block/bio.o
    crypto/akcipher.c: In function ‘crypto_akcipher_report’:
    crypto/akcipher.c:30:32: error: storage size of ‘rakcipher’ isn’t
    known
      struct crypto_report_akcipher rakcipher;
                                      ^
				      crypto/akcipher.c:34:19: error:
    ‘CRYPTOCFGA_REPORT_AKCIPHER’ undeclared (first use in this
    function)
      if (nla_put(skb, CRYPTOCFGA_REPORT_AKCIPHER,
                         ^
			 crypto/akcipher.c:34:19: note: each
    undeclared identifier is reported only once for each function it
    appears in
    crypto/akcipher.c:35:14: error: invalid application of ‘sizeof’ to
    incomplete type ‘struct crypto_report_akcipher’
           sizeof(struct crypto_report_akcipher), &rakcipher))
	                 ^
			 crypto/akcipher.c:30:32: warning: unused
    variable ‘rakcipher’ [-Wunused-variable]
      struct crypto_report_akcipher rakcipher;
                                      ^
				      scripts/Makefile.build:258:
    recipe for target 'crypto/akcipher.o' failed
    make[1]: *** [crypto/akcipher.o] Error 1
    Makefile:945: recipe for target 'crypto' failed
    make: *** [crypto] Error 2
    make: *** Waiting for unfinished jobs....

Plus... it is not easy to disable akcipher due to "interesting"
Kconfig with select maze...

I had the file, but probably had other copy of cryptouser.h somewhere.

git --work-tree=/data/l/linux-64 clean -df

helped. Thanks and sorry for the noise,
