X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=73394322a4bf4108847ba3c2eee33a81b1b44450;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[ARM] Fix context switch with ARMv6 + TLS

We accidentally corrupted the TLS value when clearing out the ARMv6
exclusive monitor.  Avoid doing so.
