In current code, we are re-reading cic->key after dead cic->key check. So, in theory, it may really re-read *after* cfq_exit_queue() seted NULL. To avoid race, we copy it to stack, then use it. With this change, I guess gcc will assign cic->key to a register or stack, and it wouldn't be re-readed.

We weren't using the recommended sequence for putting the CPU into nap mode. When I changed the idle loop, for some reason 7447A cpus started hanging when we put them into nap mode. Changing to the recommended sequence fixes that. The complexity here is that the recommended sequence is a loop that keeps putting the cpu back into nap mode. Clearly we need some way to break out of the loop when an interrupt (external interrupt, decrementer, performance monitor) occurs. Here we use a bit in the thread_info struct to indicate that we need this, and the exception entry code notices this and arranges for the exception to return to the value in the link register, thus breaking out of the loop. We use a new `local_flags' field in the thread_info which we can alter without needing to use an atomic update sequence. The PPC970 has the same recommended sequence, so we do the same thing there too. This also fixes a bug in the kernel stack overflow handling code on 32-bit, since it was causing a value that we needed in a register to get trashed. Signed-off-by: NPaul Mackerras <paulus@samba.org>

On rmmod path, cfq/as waits to make sure all io-contexts was freed. However, it's using complete(), not wait_for_completion(). I think barrier() is not enough in here.

I found that all of 2.4 and 2.6 have been letting mprotect give write permission to a readonly attachment of shared memory, whether or not IPC would give the caller that permission. SUS says "The behaviour of this function [mprotect] is unspecified if the mapping was not established by a call to mmap", but I don't think we can interpret that as allowing it to subvert IPC permissions. I haven't tried 2.2, but the 2.2.26 source looks like it gets it right; and the patch below reproduces that behaviour - mprotect cannot be used to add write permission to a shared memory segment attached readonly. This patch is simple, and I'm sure it's what we should have done in 2.4.0: if you want to go on to switch write permission on and off with mprotect, just don't attach the segment readonly in the first place. However, we could have accumulated apps which attach readonly (even though they would be permitted to attach read/write), and which subsequently use mprotect to switch write permission on and off: it's not unreasonable. I was going to add a second ipcperms check in do_shmat, to check for writable when readonly, and if not writable find_vma and clear VM_MAYWRITE. But security_ipc_permission might do auditing, and it seems wrong to report an attempt for write permission when there has been none. Or we could flag the vma as SHM, note the shmid or shp in vm_private_data, and then get mprotect to check. But the patch below is a lot simpler: I'd rather stick with it, if we can convince ourselves somehow that it'll be safe.
