linux-toradex.git/arch/arm/kernel/stacktrace.c, branch v2.6.24.2 Linux kernel for Apalis and Colibri modules [ARM] Fix stacktrace FP range checking 2007-05-30T12:15:12+00:00 Russell King rmk@dyn-67.arm.linux.org.uk 2007-05-26T11:04:17+00:00 5b10c8e436b69f25b6dcb5586bbdc5e39c20ed1d Fix an oops in the stacktrace code, caused by improper range checking. We subtract 12 off 'fp' before testing to see if it's below the low bound. However, if 'fp' were zero before, it becomes a very large positive number, causing this test to succeed where it should fail. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

 - remove the unused task argument to save_stack_trace, it's always current

then broke arm:

[ARM] Add stacktrace support and make oprofile use it 2007-04-28T08:59:37+00:00 Russell King rmk@dyn-67.arm.linux.org.uk 2007-04-28T08:59:37+00:00 f16fb1ecc5a1cb2f7cc595179d1fe55e711e599f Add support for stacktrace. Use the new stacktrace code with oprofile instead of it's version; there's no point having multiple versions of stacktracing in the kernel. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
