2011-12-02serial: sh-sci: Avoid FIFO clear for MCE toggle.Paul Mundt
When toggling the MCE support we don't want to concern ourselves with the FIFO state, so ensure that the clearing bits are masked out when updating the MCE state. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-12-02serial: sh-sci: per-port modem control.Paul Mundt
The bulk of the ports do not support any sort of modem control, so blindly twiddling the MCE bit doesn't accomplish much. We now require ports to manually specify which line supports modem control signals. While at it, tidy up the RTS/CTSIO handling in SCSPTR parts so it's a bit more obvious what's going on (and without clobbering other configurations in the process). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-11-24serial: sh-sci: Add support for loopback mode.Paul Mundt
This plugs in loopback control for SCFCR-enabled ports and plugs it in via the TIOCM_LOOP control, as others do. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-11-24serial: sh-sci: Fix up modem control handling.Paul Mundt
At the moment things like CTS/RTS are reported for all ports, while the vast majority of them do not implement support at all (and others implement support entirely in hardware). Fix up the ->get_mctrl() reporting to simply assert DSR/CAR as other drivers without control lines do. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-11-24serial: sh-sci: Clarify enable_ms/break_ctl comments.Paul Mundt
Technically there's nothing we can do for either of these, so update the comments to reflect this, rather than infering that there's additional work to be done. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-11-24serial: sh-sci: Support icount statistics for error cases.Paul Mundt
Presently the icount stats are only adjusted for the rx/tx case, this makes sure that they're updated appropriately for the non-tx/rx cases, too (specifically overruns, breaks, as well as frame and parity errors). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-11-24serial: sh-sci: Fix up SCFCR handling.Paul Mundt
Presently there are a few places that make assumptions about the existence of SCFCR, which doesn't hold true for several port types. While generally harmless, this does lead to bogus reads/writes in both the termios/runtime PM cases that are better off simply never being made in the first place. While we're at it, also get rid of a straggling PORT_SCI check that infers all non-SCI ports contain SCFCR. This doesn't presently have any impact, but as we're now able to test for the existence of registers without defering to the port type we future proof for additional port types.

This results in the access to the widget NID 0, which is obviously invalid, also a wrong capture source.

2011-11-15drivers/firmware/dmi_scan.c: make dmi_name_in_vendors more focusedJean Delvare
The current implementation of dmi_name_in_vendors() is an invitation to lazy coding and false positives [1]. Searching for a string in 8 know what you're looking for, so you should know where to look. strstr isn't fast, especially when it fails, so we should avoid calling it when it just can't succeed. Looking at the current users of the function, it seems clear to me that they are looking for a system or board vendor name, so let's limit dmi_name_in_vendors to these two DMI fields. This much better matches the function name, BTW. [1] We currently have code looking for short names in DMI data, such as "IBM", "ASUS" or "Acer". I let you guess what will happen the day other vendors ship products named, for example, "SCHREIBMEISTER", "PEGASUS" or "Acerola".

2011-11-15oom: do not kill tasks with oom_score_adj OOM_SCORE_ADJ_MINMichal Hocko
Commit c9f01245 ("oom: remove oom_disable_count") has removed the oom_disable_count counter which has been used for early break out from oom_badness so we could never select a task with oom_score_adj set to OOM_SCORE_ADJ_MIN (oom disabled). Now that the counter is gone we are always going through heuristics calculation and we always return a non zero positive value. This means that we can end up killing a task with OOM disabled because it is indistinguishable from regular tasks with 1% resp. CAP_SYS_ADMIN tasks with 3% usage of memory or tasks with oom_score_adj set but OOM enabled. Let's break out early if the task should have OOM disabled.

2011-11-15drivers/misc/eeprom: fix dependecy on 'PPC_MPC5200_GPIO'Paul Bolle
The driver for the DigsyMTC display configuration EEPROMs device got added by commit 469dded183 ("misc/eeprom: add eeprom access driver for digsy_mtc board"). Its Kconfig symbol depends on PPC_MPC5200_GPIO. But at the time that driver got added PPC_MPC5200_GPIO was already renamed to GPIO_MPC5200, by commit 6eae1ace68 ("gpio: Move mpc5200 gpio driver to drivers/gpio"). So make this driver depend on GPIO_MPC5200. And since GPIO_MPC5200 itself implies that GPIOLIB is set, that dependency can be dropped.

'readelf -n' on the s390 vmlinux file generates lots of warnings about corrupt notes. The reason is that the 'NOTE' program header has incorrect file and memory sizes. The problem is that the section following the NOTES section do not switch to a different phdr and they get added to the NOTE program section. Add a dummy entry to the linker script that switches to the data phdr before the start of the RODATA section. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2011-11-14[S390] pfault: ignore leftover completion interruptsHeiko Carstens
Ignore completion interrupts if the initial interrupt hasn't been received and the addressed task is not running. This case can only happen if leftover (pending) completion interrupt gets delivered which wasn't removed with the PFAULT CANCEL operation during cpu hotplug.
