+Subject: xtensa: fix linker script transformation for .text.unlikely
+
+From: Max Filippov <jcmvbkbc@gmail.com>
+
+commit f6a03a12ecdbe0dd80a55f6df3b7206c5a403a49 upstream.
+
+Now that binutils generate *.unlikely sections which don't follow
+documented (info as) literal section naming rules, section name
+transformation script doesn't work well resulting in the following
+errors at vmlinux link time:
+
+       main.c:(.text.unlikely+0x3): dangerous relocation: l32r: literal
+                                    placed after use: .literal.unlikely
+
+Fix section name transformation script by adding specific rule for
+.text.unlikely sections.

+Subject: xtensa: replace xtensa-specific _f{data,text} by _s{data,text}
+
+From: Geert Uytterhoeven <geert@linux-m68k.org>
+
+commit 5e7b6ed8e9bf3c8e3bb579fd0aec64f6526f8c81 upstream.
+
+commit a2d063ac216c161 ("extable, core_kernel_data(): Make sure all archs
+define _sdata") missed xtensa.  Xtensa does have a start of data marker,
+but calls it _fdata, causing
+
+    kernel/built-in.o:(.text+0x964): undefined reference to `_sdata'
+
+_stext was already defined, but it was duplicated by _fdata.
