alpha: switch __copy_user() and __do_clean_user() to normal calling conventions

2021-03-17T15:10:18+00:00

commit 8525023121de4848b5f0a7d867ffeadbc477774d upstream.

They used to need odd calling conventions due to old exception handling
mechanism, the last remnants of which had disappeared back in 2002.

alpha: Package string routines together

2021-03-17T15:10:18+00:00

commit 4758ce82e66711b1a4557577e30a5f9b88d4a4b5 upstream.

There are direct branches between {str*cpy,str*cat} and stx*cpy.
Ensure the branches are within range by merging these objects.

alpha: make short build log available for division routines

2021-03-17T15:10:18+00:00

commit 3eec0291830e4c28d09f73bab247f3b59172022b upstream.

This enables the Kbuild standard log style as follows:

  AS      arch/alpha/lib/__divlu.o
  AS      arch/alpha/lib/__divqu.o
  AS      arch/alpha/lib/__remlu.o
  AS      arch/alpha/lib/__remqu.o

alpha: merge build rules of division routines

2021-03-17T15:10:18+00:00

commit e19a4e3f1bffe45b8e2ea67fcfb0c9c88278c4cc upstream.

These four objects are generated by the same build rule, with
different compile options.  The build rules can be merged.

alpha: add $(src)/ rather than $(obj)/ to make source file path

2021-03-17T15:10:18+00:00

commit 5ed78e5523fd9ba77b8444d380d54da1f88c53fc upstream.

$(ev6-y)divide.S is a source file, not a build-time generated file.
So, it should be prefixed with $(src)/ rather than $(obj)/.

ipv4: Update parameters for csum_tcpudp_magic to their original types

2016-03-14T03:55:13+00:00

This patch updates all instances of csum_tcpudp_magic and
csum_tcpudp_nofold to reflect the types that are usually used as the source
inputs.  For example the protocol field is populated based on nexthdr which
is actually an unsigned 8 bit value.  The length is usually populated based
on skb->len which is an unsigned integer.

This addresses an issue in which the IPv6 function csum_ipv6_magic was
generating a checksum using the full 32b of skb->len while
csum_tcpudp_magic was only using the lower 16 bits.  As a result we could
run into issues when attempting to adjust the checksum as there was no
protocol agnostic way to update it.

With this change the value is still truncated as many architectures use
"(len + proto) << 8", however this truncation only occurs for values
greater than 16776960 in length and as such is unlikely to occur as we stop
the inner headers at ~64K in size.

I did have to make a few minor changes in the arm, mn10300, nios2, and
score versions of the function in order to support these changes as they
were either using things such as an OR to combine the protocol and length,
or were using ntohs to convert the length which would have truncated the
value.

I also updated a few spots in terms of whitespace and type differences for
the addresses.  Most of this was just to make sure all of the definitions
were in sync going forward.

alpha: lib: export __delay

__delay was not exported as a result while building with allmodconfig we
were getting build error of undefined symbol.  __delay is being used by:
