Sorry, seems like I am keeping you busy with the build errors.
Thanks for fixing it again (may be I need to setup all different build configs).

Subject: [PATCH -next] netxen: fix builds for SYSFS=n or MODULES=n

From: Randy Dunlap <randy.dunlap@...cle.com>

When CONFIG_MODULES=n:
drivers/net/netxen/netxen_nic_main.c:2751: error: dereferencing pointer to incomplete type
drivers/net/netxen/netxen_nic_main.c:2764: error: dereferencing pointer to incomplete type

Also needs addition of <linux/sysfs.h> for sysfs function prototypes or
stubs when CONFIG_SYSFS=n.
