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.
