Or maybe there a better fix (btw > is sysctl_vsyscall needed when !CONFIG_SYSCTL ?). Hmpf ok. I assumed they were macros who ignore their arguments. The original patch was fine, thanks. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

With 2.6.12-rc3: arch/x86_64/kernel/vsyscall.c: In function `vsyscall_init': arch/x86_64/kernel/vsyscall.c:221: error: `kernel_root_table2' undeclared (first use in this function) If you prefer, i can send a patch which sets kernel_table_root2 to NULL when CONFIG_SYSCTL is not set.

[patch] minor syctl fix in vsyscall_init
Andi, If CONFIG_SYCTL is not enabled then the x86-64 tree fails to build due to use of a symbol that is not compiled in. Don't bother compiling in the sysctl register call if not building with sysctl. matt Signed-off-by: Matt Tolentino <[EMAIL PROTECTED]> diff -urNp linux-2.6.12-rc2/arch/x86_64/kernel/vsyscall.c linux-2.6.12-rc2-m/arch/x86_64/kernel/vsyscall.c --- linux-2.6.12-rc2/arch/x86_64/kernel/vsyscall.c 2005-04-04 12:39:06.0 -0400 +++ linux-2.6.12-rc2-m/arch/x86_64/kernel/vsyscall.c2005-04-13 09:28:47.0 -0400 @@ -218,7 +218,9 @@ static int __init vsyscall_init(void) BUG_ON((VSYSCALL_ADDR(0) != __fix_to_virt(VSYSCALL_FIRST_PAGE))); map_vsyscall(); sysctl_vsyscall = 1; +#ifdef CONFIG_SYSCTL register_sysctl_table(kernel_root_table2, 0); +#endif return 0; } - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
