The implemetation of _tlbil_pid() on Freescale Book-E cores needs an msync & isync after we flash invalidate the TLBs. This was causing the following oops reported by Sebastian Andrzej Siewior: VFS: Mounted root (nfs filesystem) readonly. Freeing unused kernel memory: 148k init BUG: sleeping function called from invalid context at /home/bigeasy/git/linux-2.6-powerpc/mm/mmap.c:234 in_atomic():1, irqs_disabled():0 Call Trace: [df189df0] [c0007160] show_stack+0x48/0x148 (unreliable) [df189e30] [c0029480] __might_sleep+0xf0/0x100 [df189e40] [c0070ac0] remove_vma+0x28/0x98 [df189e50] [c0070c1c] exit_mmap+0xec/0x128 [df189e80] [c002d2f4] mmput+0x54/0xec [df189ea0] [c0030b6c] exit_mm+0x10c/0x120 [df189ed0] [c003288c] do_exit+0x1ac/0x6e8 [df189f20] [c0032e48] do_group_exit+0x80/0xac [df189f40] [c000e9dc] ret_from_syscall+0x0/0x3c BUG: scheduling while atomic: udevd/956/0x10000002 Modules linked in: Call Trace: [df189df0] [c0007160] show_stack+0x48/0x148 (unreliable) [df189e30] [c002ac88] __schedule_bug+0x58/0x6c [df189e40] [c023e6cc] schedule+0xa8/0x4a8 [df189e90] [c002ad6c] __cond_resched+0x38/0x64 [df189ea0] [c023ebc8] _cond_resched+0x3c/0x58 [df189eb0] [c0030e70] put_files_struct+0x90/0xec [df189ed0] [c00328a8] do_exit+0x1c8/0x6e8 [df189f20] [c0032e48] do_group_exit+0x80/0xac [df189f40] [c000e9dc] ret_from_syscall+0x0/0x3c Signed-off-by: Kumar Gala <galak@kernel.crashing.org> |
