From: Christian Brauner Date: Sun, 24 May 2020 21:14:23 +0000 (+0200) Subject: c6x: switch to copy_thread_tls() X-Git-Tag: howlett/maple_spf/20210104~1363^2~7 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=e0daa22c292b5835a946716b9a2092b30c7d9d31;p=users%2Fjedix%2Flinux-maple.git c6x: switch to copy_thread_tls() Use the copy_thread_tls() calling convention which passes tls through a register. This is required so we can remove the copy_thread{_tls}() split and remove the HAVE_COPY_THREAD_TLS macro.
