| |
When 2.6.12-rc1-mm1 is configured for a ppc64/G5, so CONFIG_PPC_PSERIES is disabled, linking of vmlinux fails with:
arch/ppc64/kernel/built-in.o(.text+0x7de0): In function `.sys_call_table32': : undefined reference to `.ppc_rtas' arch/ppc64/kernel/built-in.o(.text+0x8668): In function `.sys_call_table': : undefined reference to `.ppc_rtas' make: *** [.tmp_vmlinux1] Error 1
This is because 2.6.12-rc1-mm1 contains the apparently broken patch:
>--- linux-2.6.12-rc1/arch/ppc64/kernel/misc.S 2005-03-17 21:43:54.000000000 -0800 >+++ 25/arch/ppc64/kernel/misc.S 2005-03-21 01:07:42.000000000 -0800 >@@ -680,7 +680,7 @@ _GLOBAL(kernel_thread) > ld r30,-16(r1) > blr > >-#ifndef CONFIG_PPC_PSERIES /* hack hack hack */ >+#ifdef CONFIG_PPC_RTAS /* hack hack hack */ > #define ppc_rtas sys_ni_syscall > #endif
PPC_PSERIES implies PPC_RTAS. It seems someone tried to clean up the condition but accidentally negated it: on PSERIES the system call will now go to sys_ni_syscall, and on !PSERIES linking will fail.
Fix: negate the condition.
