kbuild: Fix gcc -x syntax

2012-10-12T20:38:37+00:00

commit b1e0d8b70fa31821ebca3965f2ef8619d7c5e316 upstream.

The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.

This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.

Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

cpupower tool: allow to build in a separate directory

2012-03-03T13:40:10+00:00

This patch allows cpupower tool to generate its output files in a
seperate directory. This is now possible by passing the 'O=' to
the command line.

This can be usefull for a normal user if the kernel source code is
located in a read only location.

This is patch stole some bits of the perf makefile.

cpupower tool: makefile: simplify the recipe used to generate cpupower.pot target

2012-03-03T13:40:10+00:00

Use the '-p' and '-o' switches to specify the pathname of the output
file to xgettext(1). This avoids to move manually the output file if
xgettext(1) succeeds.

cpupower tool: remove use of undefined variables from the clean target of the top makefile

2012-03-03T13:40:10+00:00

UTIL_BINS and IDLE_OBJS variables are not defined at all, so
there's no need to remove their content from the 'clean' target.

cpupower: Remove unneeded code and by that fix a memleak

2012-03-03T13:40:10+00:00

Looks like some not needed debug code slipped in.
Also this code:
tmp = sysfs_get_idlestate_name(cpu, idlestates - 1);
performs a strdup and the mem was not freed again.
-> delete it.

cpupower: Fix number of idle states

2012-03-03T13:40:09+00:00

The number of idle states was wrong.
The POLL idle state (on X86) was missed out:
Number of idle states: 4
Available idle states: C1-NHM C3-NHM C6-NHM

While the POLL is not a real idle state, its
statistics should still be shown. It's now also
explained in a detailed manpage.
This should fix a bug of missing the first idle
state on other archs.
