Remove a support of ISA addresses predefined at compile time. It is unused (filled by zeroes) and prolongs the code. Don't initialize global array and add `ioaddr' module param description. Signed-off-by:

- use dev_* for printing in pci probe function - move ISA p[rints directly into isa find function, do not postpone it. Remove macros bound to it then. - prepend some prints by "mxser: " to know what it belongs to Signed-off-by:

- remove unused mxvar_diagflag - move mxser_msr into the only user/function - GMStatus, hmm, fix race-prone access to it. We need only one instance for real, not MXSER_PORTS. Move it to MOXA_GETMSTATUS ioctl. - mxser_mon_ext, almost the same, but alloc it on heap, since it has more than 2 kilos. - fix indexing, `i' is not the index value, `i * MXSER_PORTS_PER_BOARD + j' is Signed-off-by:

- remove break ctl from ioctl handler, it's never reached, since tty_ops->break_ctl is defined (mxser break handling is done in software) - mark MOXA_GET_MAJOR as deprecated - fix TIOCGICOUNT (some retval non-checks of put_user). Use copy_to_user to whole structure instead. Signed-off-by:

This patch proposes an alternative to the "magical positive-versus-negative number trick" Andrew complained about last week in http://lkml.org/lkml/2008/6/24/418. This had been introduced with the patches that scale msgmni to the amount of lowmem. With these patches, msgmni has a registered notification routine that recomputes msgmni value upon memory add/remove or ipc namespace creation/ removal. When msgmni is changed from user space (i.e. value written to the proc file), that notification routine is unregistered, and the way to make it registered back is to write a negative value into the proc file. This is the "magical positive-versus-negative number trick". To fix this, a new proc file is introduced: /proc/sys/kernel/auto_msgmni. This file acts as ON/OFF for msgmni automatic recomputing. With this patch, the process is the following: 1) kernel boots in "automatic recomputing mode" /proc/sys/kernel/msgmni contains the value that has been computed (depends on lowmem) /proc/sys/kernel/automatic_msgmni contains "1" 2) echo <val> > /proc/sys/kernel/msgmni . sets msg_ctlmni to <val> . de-activates automatic recomputing (i.e. if, say, some memory is added msgmni won't be recomputed anymore) . /proc/sys/kernel/automatic_msgmni now contains "0" 3) echo "0" > /proc/sys/kernel/automatic_msgmni . de-activates msgmni automatic recomputing this has the same effect as 2) except that msg_ctlmni's value stays blocked at its current value) 3) echo "1" > /proc/sys/kernel/automatic_msgmni . recomputes msgmni's value based on the current available memory size and number of ipc namespaces . re-activates automatic recomputing for msgmni.

The attached patch: - reverses the locking order of ulp->lock and sem_lock: Previously, it was first ulp->lock, then inside sem_lock. Now it's the other way around. - converts the undo structure to rcu. Benefits: - With the old locking order, IPC_RMID could not kfree the undo structures. The stale entries remained in the linked lists and were released later. - The patch fixes a a race in semtimedop(): if both IPC_RMID and a semget() that recreates exactly the same id happen between find_alloc_undo() and sem_lock, then semtimedop() would access already kfree'd memory.

This is a trivial patch that renames: . alloc_layer to get_from_free_list since it idr_pre_get that actually allocates memory. . free_layer to move_to_free_list since memory is not actually freed there. This makes things more clear for the next patches. Signed-off-by:
