From 0517deed78be9cc9ce9799bf15da58fd0d2078bb Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 15 Apr 2008 00:49:04 -0700 Subject: netconsole: only set CON_PRINTBUFFER if the user specifies a netconsole Since 0bcc1816188e570bde1d56a208996660f2633ae0 (netconsole: Support dynamic reconfiguration using configfs), the netconsole is always registered, regardless of whether the user actually specified a netconsole configuration on the command line. However because netconsole has CON_PRINTBUFFER set, when it is registered it causes the printk buffer to be replayed to all consoles. When there is no netconsole configured this is a) pointless, and b) somewhat annoying for the user of the existing console. So instead we should only set CON_PRINTBUFFER if there is a netconsole configuration found on the command line. This retains the existing behaviour if a netconsole is setup by the user, and avoids spamming other consoles when we're only registering for the dynamic netconsole case.

We must use the host-device's (PCI) struct device for any DMA operation instead of the SSB device. For this we add a new struct device pointer to the SSB device structure that will always point to the right device for DMAing. Without this patch b43 and b44 drivers won't work on complex-DMA architectures, that for example need dev->archdata for DMA operations. Signed-off-by: Michael Buesch Signed-off-by: John W.
