Subject: [IA64] Fix trap #45 handling
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=169ec523c34212f6e382186bce88f17eba4cad49;p=linux-beck.git

[IA64] Fix trap #45 handling

In this case, the original author did not provide the related reason
string for die_if_kernel(), so the 'buf' is not initialized.

The original author wants to generic a 'SIGSEGV' and 'return', not want
to 'break' to fall to die.

[Probably irrelevent since we no longer support IA-32 execution. -Tony]
