Subject: serial: sh-sci: Kill off breakpoint in break IRQ.
X-Git-Tag: v2.6.22-rc1~825^2~29
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8248daac6b9cde7748a659dcabea6584d62a9fd8;p=linux-2.6

serial: sh-sci: Kill off breakpoint in break IRQ.

With the GDB stub being entered via a special sysrq trigger,
we don't want to hit it directly from sci_br_interrupt().
Without this, there is access to the other sysrq triggers when
kgdb is enabled.
