[ltt-dev] 2.6.29-rc7-lttng-0.110 broken with CONFIG_SLUB

[Josh Boyer]

Hi All,

I was attempting to build a simple ppc64_defconfig using
the latest LTTng tag from git.  When doing a:

	make ppc64_defconfig
	make

I get the error below.

Looking at it a bit, it seems that 6ff4cecc57ea21004e1f0b15cb1319b52110bbd3
adds a "#include <asm/time.h>" to the arch/powerpc/include/asm/timex.h file.

This explodes because it is included before CLOCK_TICK_RATE is defined in
that file, and the include dependencies when CONFIG_SLUB is set eventually
cause this missing define to produce the error.

I tried moving the #include <asm/time.h> below the CLOCK_TICK_RATE
definition, but it just breaks the build at a later point.

Has LTTng been built with CONFIG_SLUB before?  I'll note that this isn't
even into the LTTng parts yet and it's causing problems.  I'd eventually
like to use this on an embedded board such as 
arch/powerpc/configs/44x/sequioa_defconfig, however for this report I
thought I'd use a pretty common config like ppc64_defconfig.
