Subject: ARM: make SWP emulation explicit on !CPU_USE_DOMAINS
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0193c00e85a35ceee7856c89c25b34d5752e0baa;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: make SWP emulation explicit on !CPU_USE_DOMAINS

SWP emulation requires that CPU domain support is disabled in order to
work safely.  Make that explicit in the kernel configuration to prevent
illegal configurations being generated.
