linkage.h: fix build breakage due to symbol prefix handling
Al's commit e1b5bb6d1236 ("consolidate cond_syscall and SYSCALL_ALIAS
declarations") broke the build on blackfin and metag due to the
following code:
#ifndef SYMBOL_NAME
#ifdef CONFIG_SYMBOL_PREFIX
#define SYMBOL_NAME(x) CONFIG_SYMBOL_PREFIX ## x
#else
#define SYMBOL_NAME(x) x
#endif
#endif
#define __SYMBOL_NAME(x) __stringify(SYMBOL_NAME(x))
__stringify literally stringifies CONFIG_SYMBOL_PREFIX ##x, so you get
lines like this in kernel/sys_ni.s:
.weak CONFIG_SYMBOL_PREFIXsys_quotactl
.set CONFIG_SYMBOL_PREFIXsys_quotactl,CONFIG_SYMBOL_PREFIXsys_ni_syscall
The patches in Rusty's modules-next tree such as "CONFIG_SYMBOL_PREFIX:
cleanup." cleans up the whole mess around symbol prefixes, so this patch
just attempts to fix the build in the meantime.
The intermediate definition of SYMBOL_NAME above isn't used and is
incorrect when CONFIG_SYMBOL_PREFIX is defined as CONFIG_SYMBOL_PREFIX
is a quoted string literal, so define __SYMBOL_NAME directly depending
on CONFIG_SYMBOL_PREFIX.
