Bug 739596

Description of problem:

Attempting to use systemtap on fc14. Systemtap builds kernel modules and installs them to instrument the machine. For this to work need to have kernel-devel (or kernel-tegra-devel) able to build modules on the machine. The machine attempting this on is a trimslice pro.


Version-Release number of selected component (if applicable):

kernel-tegra-devel-2.6.40.3-0.fc14.armv7l
kernel-tegra-2.6.40.3-0.fc14.armv7l
kernel-headers-2.6.40.3-0.fc14.armv5tel
kernel-tegra-debuginfo-2.6.40.3-0.fc14.armv7l
kernel-debuginfo-common-armv7l-2.6.40.3-0.fc14.armv7l
systemtap-1.6-1.fc14.armv5tel

How reproducible:

Every time.

Steps to Reproduce:
1. Install the rpms above from koji (note needed to rebuild systemtap rpm because of corruption in the koji files)
2. As root run the example from http://sourceware.org/systemtap/SystemTap_Beginners_Guide/using-systemtap.html#testing:
stap -v -e 'probe vfs.read {printf("read performed\n"); exit()}'
3.
  
Actual results:

Unable to run the example get something of like the following:


# stap -v -e 'probe vfs.read {printf("read performed\n"); exit()}'

compilation terminated.


Expected results:

The instrumentation compiled into a kernel module which include the following line in the output:

read performed



Additional info:

Looking at local rpmbuild of kernel rpm see:

$ls rpmbuild/BUILD/kernel-2.6.39.fc14/linux-2.6.39.armv5tel/arch/arm/mach-tegra/include/mach/
barriers.h     entry-macro.S  irqs.h       powergate.h           timex.h
clkdev.h       gpio.h         kbc.h        sdhci.h               uncompress.h

dma.h          iomap.h        pinmux-t2.h  tegra_wm8903_pdata.h

Don't see the include/mach in the kernel-tegra-devel:

$ls /usr/src/kernels/2.6.40.3-0.fc14.armv7l.tegra/arch/arm/mach-tegra/
Kconfig  Makefile  Makefile.boot


Manually copied the missing include directory over to /usr/src/kernels/2.6.40.3-0.fc14.armv7l.tegra/arch/arm/mach-tegra/ and things ran.
