Christophe Leroy 96f391cf40 Revert "powerpc/64: Fix checksum folding in csum_add()" This reverts commit `6ad966d730`. That commit was pointless, because csum_add() sums two 32 bits values, so the sum is 0x1fffffffe at the maximum. And then when adding upper part (1) and lower part (0xfffffffe), the result is 0xffffffff which doesn't carry. Any lower value will not carry either. And behind the fact that this commit is useless, it also kills the whole purpose of having an arch specific inline csum_add() because the resulting code gets even worse than what is obtained with the generic implementation of csum_add() 0000000000000240 <.csum_add>: 240: 38 00 ff ff li r0,-1 244: 7c 84 1a 14 add r4,r4,r3 248: 78 00 00 20 clrldi r0,r0,32 24c: 78 89 00 22 rldicl r9,r4,32,32 250: 7c 80 00 38 and r0,r4,r0 254: 7c 09 02 14 add r0,r9,r0 258: 78 09 00 22 rldicl r9,r0,32,32 25c: 7c 00 4a 14 add r0,r0,r9 260: 78 03 00 20 clrldi r3,r0,32 264: 4e 80 00 20 blr In comparison, the generic implementation of csum_add() gives: 0000000000000290 <.csum_add>: 290: 7c 63 22 14 add r3,r3,r4 294: 7f 83 20 40 cmplw cr7,r3,r4 298: 7c 10 10 26 mfocrf r0,1 29c: 54 00 ef fe rlwinm r0,r0,29,31,31 2a0: 7c 60 1a 14 add r3,r0,r3 2a4: 78 63 00 20 clrldi r3,r3,32 2a8: 4e 80 00 20 blr And the reverted implementation for PPC64 gives: 0000000000000240 <.csum_add>: 240: 7c 84 1a 14 add r4,r4,r3 244: 78 80 00 22 rldicl r0,r4,32,32 248: 7c 80 22 14 add r4,r0,r4 24c: 78 83 00 20 clrldi r3,r4,32 250: 4e 80 00 20 blr Fixes: `6ad966d730` ("powerpc/64: Fix checksum folding in csum_add()") Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Acked-by: Paul Mackerras <paulus@ozlabs.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>		2018-05-18 00:09:04 +10:00

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
