Subject: ARM: boot: quote aliased symbol names in string.c
Patch "treewide: Remove stringification from __alias macro definition"
causes arguments to __alias to no longer be quoted automatically, which
breaks CONFIG_KASAN on ARM after commit d6d51a96c7d6 ("ARM: 9014/2:
Replace string mem* functions for KASan"):
arch/arm/boot/compressed/string.c:24:1: error: attribute 'alias' argument not a string
24 | void *__memcpy(void *__dest, __const void *__src, size_t __n) __alias(memcpy);
| ^~~~
arch/arm/boot/compressed/string.c:25:1: error: attribute 'alias' argument not a string
25 | void *__memmove(void *__dest, __const void *__src, size_t count) __alias(memmove);
| ^~~~
arch/arm/boot/compressed/string.c:26:1: error: attribute 'alias' argument not a string
26 | void *__memset(void *s, int c, size_t count) __alias(memset);
| ^~~~
make[3]: *** [scripts/Makefile.build:283: arch/arm/boot/compressed/string.o] Error 1
Quote the names like the treewide patch does so there is no more error.
