oprofile: Introduce new oprofile sample add function (oprofile_add_ext_hw_sample)
This patch introduces a new oprofile sample add function (oprofile_add_ext_hw_sample) that can also take task_struct as an argument, which is used by the hwsampler kernel module when copying hardware samples to OProfile buffers. Applied with following changes: * removed #include <linux/module.h> * whitespace changes * removed conditional compilation (CONFIG_HAVE_HWSAMPLER) * modified order of functions * fix missing function definition in header file Signed-off-by: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com> Signed-off-by: Maran Pakkirisamy <maranp@linux.vnet.ibm.com> Signed-off-by: Heinz Graalfs <graalfs@linux.vnet.ibm.com> Acked-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Robert Richter <robert.richter@amd.com>
