Description kfm 2006-03-07 20:48:53 UTC 
According to the commit "arch/ia64/kernel/unaligned.c erroneously marked die_if_kernel() with a "noreturn" attribute ... which is silly (it returns whenever the argument regs say that the fault happened in user mode, as one might expect given the "if_kernel" part of its name!). Thanks to Alan and Gareth for pointing this out." The following kernels/patchsets are unaffected:

  * >=vanilla-sources-2.6.15.6
  * >=gentoo-sources-2.6.15-r7
  * >=genpatches-2.6.15-10

Patch. Also applies to 2.6.14.
Comment 2 Tim Yamin (RETIRED) gentoo-dev 2006-03-11 11:09:22 UTC 
IA64 only has gentoo-sources keyworded (and I've now stabled -r7) so this can be closed.
