Subject: [PATCH] x86/relocs: Make per_cpu_load_addr static
|
||
|
|
|
||
|
|
per_cpu_load_addr is only used for 64-bit relocations, but is
|
||
|
|
declared in both configurations of relocs.c - with different
|
||
|
|
types. This has undefined behaviour in general. GNU ld is
|
||
|
|
documented to use the larger size in this case, but other tools
|
||
|
|
may differ and some warn about this.
