+Subject: ARM: 9133/1: mm: proc-macros: ensure *_tlb_fns are 4B aligned
+
+From: Nick Desaulniers <ndesaulniers@google.com>
+
+commit e6a0c958bdf9b2e1b57501fc9433a461f0a6aadd upstream.
+
+A kernel built with CONFIG_THUMB2_KERNEL=y and using clang as the
+assembler could generate non-naturally-aligned v7wbi_tlb_fns which
+results in a boot failure. The original commit adding the macro missed
+the .align directive on this data.

+Subject: ARM: 9134/1: remove duplicate memcpy() definition
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+commit eaf6cc7165c9c5aa3c2f9faa03a98598123d0afb upstream.
+
+Both the decompressor code and the kasan logic try to override
+the memcpy() and memmove()  definitions, which leading to a clash
+in a KASAN-enabled kernel with XZ decompression:
+
+arch/arm/boot/compressed/decompress.c:50:9: error: 'memmove' macro redefined [-Werror,-Wmacro-redefined]
+ #define memmove memmove
+        ^
+arch/arm/include/asm/string.h:59:9: note: previous definition is here
+ #define memmove(dst, src, len) __memmove(dst, src, len)
+        ^
+arch/arm/boot/compressed/decompress.c:51:9: error: 'memcpy' macro redefined [-Werror,-Wmacro-redefined]
+ #define memcpy memcpy
+        ^
+arch/arm/include/asm/string.h:58:9: note: previous definition is here
+ #define memcpy(dst, src, len) __memcpy(dst, src, len)
+        ^
+
+Here we want the set of functions from the decompressor, so undefine
+the other macros before the override.
