Subject: [PATCH 5.2 51/61] Revert "x86/build: Move _etext to actual end of .text"

From: Ross Zwisler <zwisler@...omium.org>

commit 013c66edf207ddb78422b8b636f56c87939c9e34 upstream.

This reverts commit 392bef709659abea614abfe53cf228e7a59876a4.

Per the discussion here:

  https://lkml.kernel.org/r/201906201042.3BF5CD6@keescook

the above referenced commit breaks kernel compilation with old GCC
toolchains as well as current versions of the Gold linker.

Revert it to fix the regression and to keep the ability to compile the
kernel with these tools.
