[PATCH] uml: fix oops related to exception table
Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>
Prevent the kernel from oopsing during the extable sorting, as it can do
now, because the extable is in the readonly section of the binary.
Jeff says: The exception table turned RO in 2.6.11-rc3-mm1 for some reason.
Moving it causes it to land in the writable data section of the binary.
Paolo says: This patch fixes a oops on startup, which can be easily
triggered by compiling with CONFIG_MODE_TT disabled, and STATIC_LINK either
disabled or enabled. The resulting kernel will always Oops on startup,
after printing this simple output:
I've verified, by binary search on the BitKeeper repository (synced up as
of 2.6.12-rc2), starting from the range 2.6.11-2.6.12-rc1, that this bug
shows up on BitKeeper revisions in the range [@1.1994.11.168,+inf), i.e.
starting from this:
[PATCH] lib/sort: Replace insertion sort in exception tables
Since UML does not use the exception table, it's likely that insertion sort
didn't happen to write anything on the table.
