Geert Uytterhoeven fee3fd4fd2 ARM: 8338/1: kexec: Relax SMP validation to improve DT compatibility ... When trying to kexec into a new kernel on a platform where multiple CPU cores are present, but no SMP bringup code is available yet, the kexec_load system call fails with: kexec_load failed: Invalid argument The SMP test added to machine_kexec_prepare() in commit 2103f6cba6 ("ARM: 7807/1: kexec: validate CPU hotplug support") wants to prohibit kexec on SMP platforms where it cannot disable secondary CPUs. However, this test is too strict: if the secondary CPUs couldn't be enabled in the first place, there's no need to disable them later at kexec time. Hence skip the test in the absence of SMP bringup code. This allows to add all CPU cores to the DTS from the beginning, without having to implement SMP bringup first, improving DT compatibility.
