4 | X-Git-Url: http://www.kernel.org/git/?p=linux/kernel/git/stable/linux-2.6.16.y.git;a=commitdiff;h=355bd3d4ea761a66880088ac2d0c5c95866df4a6 |

6 | [PATCH] x86_64: Pass -32 to the assembler when compiling the 32bit vsyscall pages |
7 | |
8 | This quietens warnings and actually fixes a bug. The unwind tables would |
9 | come out wrong without -32, causing pthread cancellation during them |
10 | to crash in the gcc runtime. |
11 | |
12 | The problem seems to only happen with newer binutils |
13 | (it doesn't happen with 2.16.91.0.2 but happens wit 2.16.91.0.5) |
14 | |
15 | Thanks to Brian Baker @ HP for test case and initial analysis. |
