Subject: 4GB+DEBUG_PAGEALLOC oopses with 2.6.0-test3-mm1
Date: Sun, 10 Aug 2003 12:33:02 +0200 [thread overview]
Message-ID: <3F361F5E.10106@colorfullife.com> (raw)
Hi Ingo,
I'm running into crashes in copy_mount_options with
CONFIG_DEBUG_PAGEALLOC and 4GB in 2.6.0-test3-mm1:
The functions in mm/usercopy assume that no exception handling is
required if fs is KERNEL_DS. This is not true: at least the mount
options copy and the i386 traps handler assume exception handling with
fs==KERNEL_DS.
How should this be fixed? I don't see a simple, portable way to
implement exception handling for the kernel address space.
