crypto: serpent - mark __serpent_setkey_sbox noinline
[ Upstream commit 473971187d6727609951858c63bf12b0307ef015 ]
The same bug that gcc hit in the past is apparently now showing
up with clang, which decides to inline __serpent_setkey_sbox:
crypto/serpent_generic.c:268:5: error: stack frame size of 2112 bytes in function '__serpent_setkey' [-Werror,-Wframe-larger-than=]
Marking it 'noinline' reduces the stack usage from 2112 bytes to
192 and 96 bytes, respectively, and seems to generate more
useful object code.
Fixes: c871c10e4ea7 ("crypto: serpent - improve __serpent_setkey with UBSAN")
