** Description changed: [Impact] on ARM64 servers we observe call trace "arm64/mm: Found insecure W+X mapping at address 0000000000a99000/0xa99000" while booting. These messages are a false positive and triggered at random. [Test] - There is no reliable way to reproduce these warnings, they are triggered at random. But these messages can appear on any ARM64 server Cavium, Qualcomm etc. A test kernel is available in - ppa:manjo/lp1769696 and the kernel was boot tested on a QDF2400 system. + There is no reliable way to reproduce these warnings, they are triggered at random.
