tools: Copy linux/{hash,poison}.h and check for drift

2016-07-18T21:41:50+00:00

We were also using this directly from the kernel sources, the two last
cases, fix it.

tools: Copy the bitops files accessed from the kernel and check for drift

2016-07-18T21:33:41+00:00

copy some more kernel files accessed from tools/, check for drift.

tools: Simplify BITS_PER_LONG define

2016-07-15T20:26:41+00:00

Do it using (__CHAR_BIT__ * __SIZEOF_LONG__), simpler, works everywhere,
reduces the complexity by ditching CONFIG_64BIT, that was being
synthesized from yet another set of defines, which proved fragile,
breaking the build on linux-next for no obvious reasons.

Committer Note:

Except on:

gcc version 4.1.2 20080704 (Red Hat 4.1.2-55)

Fallback to __WORDSIZE in that case...

tools: Make "__always_inline" just "inline" on Android

2016-07-14T15:03:04+00:00

As the gcc there is producing tons of:

  "warning: always_inline function might not be inlinable"

At least on android-ndk-r12/platforms/android-24/arch-arm, so, for the
time being, use this big hammer.

tools: Fix up BITS_PER_LONG setting

2016-07-13T18:04:04+00:00

It was set based on CONFIG_64BIT, that is available only when using
Kconfig, which we're working towards but not to the point of having this
CONFIG variable set, so synthesize it from available compiler defined
defines, __SIZEOF_LONG__ or, lacking that, __WORDSIZE.

tools: Work around BITS_PER_LONG related build failure in objtool

2016-07-13T07:37:43+00:00

The objtool build fails with the recent changes to the bits-per-long
headers:

  tools/include/linux/bitops.h:12:0: error: "BITS_PER_LONG" redefined [-Werror]

Which got introduced by:

  bb9707077b4e tools: Copy the bitsperlong.h files from the kernel

Work it around for the time being.

tools: Copy the bitsperlong.h files from the kernel

2016-07-12T18:20:39+00:00

We use it in bitops/__ffs.h and bitops/atomic.h, that we also got from
the kernel, but were getting it from either newer systems that carry it
in /usr/include, or from the kernel sources, that we decided not to
touch from tools/ code. Fix it.
