With grsecurity-2.2.2-2.6.39.4-201108071438 I get the following on i386:

Also, when cross-compiling from amd64 to i386, I get:

CC kernel/bounds.s
kernel/bounds.c:1:0: error: CPU you selected does not support x86-64 instruction set
kernel/bounds.c:1:0: warning: -mregparm is ignored in 64-bit mode
make[3]: *** [kernel/bounds.s] Erreur 1

I've been meaning to post about this too. Several drivers also fail to compile with similar errors.

Code: Select all

drivers/staging/hv/hv_mouse.c: In function 'reportdesc_callback':
drivers/staging/hv/hv_mouse.c:901:3: error: assignment of read-only location '*hid_dev->ll_driver'
drivers/staging/hv/hv_mouse.c:902:3: error: assignment of read-only location '*hid_dev->ll_driver'

Enable SMP for now as a workaround.

Already is enabled for me. Full error log: http://kpaste.net/8a9?raw

Your case is different than that of the OP. Some patches will have to be created for those drivers. If you don't need them, they can be disabled. I'll try to come up with a patch soon for it however.

The test patch I just uploaded should resolve the staging driver compilation errors. Let me know if any of the errors persist.

-Brad

Yeah that fixes it. Thanks.
