Subject: fix x32 __set_thread_area failure due to junk in upper bits
X-Git-Tag: v1.1.9~7
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=2d5c74c21e0483128624c43d4399ef49e057e264;p=oweals%2Fmusl.git

fix x32 __set_thread_area failure due to junk in upper bits

the kernel does not properly clear the upper bits of the syscall
argument, so we have to do it before the syscall.
