ppc: propagate the calling conventions change down to csum_partial_copy_generic() (2020-08-20 15:45:22 -0400)
----------------------------------------------------------------
Al Viro (19):
skb_copy_and_csum_bits(): don't bother with the last argument
icmp_push_reply(): reorder adding the checksum up
unify generic instances of csum_partial_copy_nocheck()
csum_partial_copy_nocheck(): drop the last argument
csum_and_copy_..._user(): pass 0xffffffff instead of 0 as initial sum
saner calling conventions for csum_and_copy_..._user()
alpha: propagate the calling convention changes down to csum_partial_copy.c helpers
arm: propagate the calling convention changes down to csum_partial_copy_from_user()
m68k: get rid of zeroing destination on error in csum_and_copy_from_user()
sh: propage the calling conventions change down to csum_partial_copy_generic()
i386: propagate the calling conventions change down to csum_partial_copy_generic()
sparc32: propagate the calling conventions change down to __csum_partial_copy_sparc_generic()
mips: csum_and_copy_{to,from}_user() are never called under KERNEL_DS
mips: __csum_partial_copy_kernel() has no users left
mips: propagate the calling convention change down into __csum_partial_copy_..._user()
xtensa: propagate the calling conventions change down into csum_partial_copy_generic()
sparc64: propagate the calling convention changes down to __csum_partial_copy_...()
amd64: switch csum_partial_copy_generic() to new calling conventions
ppc: propagate the calling conventions change down to csum_partial_copy_generic()
