From: Sebastian Andrzej Siewior <bige...@linutronix.de>
Adding -no-PIE to the fstack protector check. -no-PIE was introduced
before -fstack-protector so there is no need for a runtime check.
Without it the build stops:
|Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong available
but compiler is broken
due to -mcmodel=kernel + -fPIE if -fPIE is enabled by default.
Tagging it stable so it is possible to compile recent stable kernels as
well.
