Oleksandr Tymoshenko	1b930fb786	Rework MIPS PMC code: ... - Replace MIPS24K-specific code with more generic framework that will make adding new CPU support easier - Add MIPS24K support for new framework - Limit backtrace depth to 1 for stability reasons and add option HWPMC_MIPS_BACKTRACE to override this limitation	2012-03-22 18:01:23 +00:00
Oleksandr Tymoshenko	d43022a1b3	- Remove unncessary type casts ... - Make kernel backtrace routine more robust by refusing to backtrace further when encountered function that is possibly modifies SP value	2012-03-14 23:46:07 +00:00
