Subject: [PATCH] sysrq and 8250 serial console 2.6.10-rc1-mm3
Date: Tue, 16 Nov 2004 14:17:33 -0500	[thread overview]
Message-ID: <1100632653.14403.2.camel@localhost.localdomain> (raw)

I don't know if anyone else caught this, but the sysrq doesn't work with
the serial console for 8250.  This is a simple patch, the serial_8250.h
also calls serial_core.h before SUPPORT_SYSRQ is defined. And thus the
inlines in serial core do not support sysrq.

Here's the fix, I was even more paranoid and put the define before all
serial headers.
