Commit 9436d5c32b1ac8d4efdbc933611b5e699908854e

Authored by Al Viro
1 parent 9489e9dcae
Exists in smarc-l5.0.0_1.0.0-ga and in 5 other branches imx_3.10.17_1.0.1_ga, imx_3.10.53_1.1.0_ga, imx_3.14.28_1.0.0_ga, smarc-imx_3.10.53_1.1.0_ga, smarc-imx_3.14.28_1.0.0_ga

um: get_safe_registers() should be done in flush_thread(), not start_thread() 

... or we'll end up buggering the results of ELF_PLAT_INIT()
