linux-next: build failure after merge of the final tree

[Stephen Rothwell]

Hi Al,

After merging the final tree, today's linux-next build (sparc64 defconfig)
failed like this:

arch/sparc/kernel/head_64.o: In function `sys64_execve':
(.text+0x1f58): relocation truncated to fit: R_SPARC_WDISP19 against symbol 
`sys_execve' defined in .text section in fs/built-in.o
arch/sparc/kernel/head_64.o: In function `sys32_execve':
(.text+0x1f64): relocation truncated to fit: R_SPARC_WDISP19 against symbol 
`compat_sys_execve' defined in .text section in fs/built-in.o

Probably caused by commit 3223f8aab885 ("sparc64: convert to generic
execve") and following from the signal tree.

I have added this patch you suggested on IRC:

From: Stephen Rothwell <s...@canb.auug.org.au>
Date: Tue, 16 Oct 2012 14:43:51 +1100
Subject: [PATCH] sparc: fixup for conversion to generic execve

Fixes these errors:

arch/sparc/kernel/head_64.o: In function `sys64_execve':
(.text+0x1f58): relocation truncated to fit: R_SPARC_WDISP19 against symbol 
`sys_execve' defined in .text section in fs/built-in.o
arch/sparc/kernel/head_64.o: In function `sys32_execve':
(.text+0x1f64): relocation truncated to fit: R_SPARC_WDISP19 against symbol 
`compat_sys_execve' defined in .text section in fs/built-in.o
