[PATCH v2] crypto: caam - treat SGT address pointer as u64

2016-09-30 Thread Tudor Ambarus
Even for i.MX, CAAM is able to use address pointers greater than 32 bits, the address pointer field being interpreted as a double word. Enforce u64 address pointer in the sec4_sg_entry struct. This patch fixes the SGT address pointer endianness issue for 32bit platforms where core endianness != ca

Hi Linus: This push fixes a weakness in random number generation of file random.c. The two polynomials of LFSR used in Linux/drivers/char/random.c are P1(X) = x^128 + x^104 + x^76 + x^51 +x^25 + x + 1, for input pool P2(X) = x^32 + x^26 + x^19 + x^14 + x^7 + x + 1 , for output pool These polynom
