2007-10-14USBHID: report descriptor fix for MacBook JIS keyboardTomoya Adachi
This patch fixes the problem, that Japanese MacBook doesn't recognize some keys like '\'(yen, or backslash), '|'(pipe), and '_'(underscore). It is due to that MacBook JIS keyboard (jp106) sends wrong report descriptor. It saids "logical maximum = 0x65", so Keyboard.0089 is mapped to Key.Unknown, while it should be accepted as Key.Yen.

2007-10-14HID: enable hiddev for the SantaRosa MacBookPro IR receiverStelian Pop
The infrared remote receiver found in the SantaRosa MacBookPro laptops (MacBookPro3,1) need to be forced to expose a HIDDEV interface (instead of HIDINPUT) so that lirc can access it using the 'macmini' driver. The patch below adds the required quirk for forcing the HIDDEV interface to be activated (HID_QUIRK_HIDDEV) and introduces a new quirk which forces the HIDINPUT interface to be ignored (HID_QUIRK_IGNORE_HIDINPUT). Note that Apple calls this receiver 'IRController4' (info taken from Apple's driver Info.plist). Older Mac{Book,Mini,Pro}s seem to all use the 'IRController1' device (USB id 05ac:8240) which doesn't need those quirks.

2007-10-14HID: Report usage codes of keys as EV_MSC scancode eventsJiri Kosina
Current HID layer does not report usage codes to the input layer. This feature was previously removed, because it caused unnecessary storm of events in cases of positioning devices, etc. This patch adds reporting of usage codes as EV_MSC events only for key events. We issue the EV_MSC event only if the state of the key corresponding to the given code has changed, so that we don't report usages that are sent in every report even if the state hasn't changed (for example Shift/Caps Lock/... states as sent by various keyboards). This functionality is required at least by KeyTouch in order to provide convenient means for remapping the usage codes.

2007-10-14HID: ignore all non-LED usages in output fields in hid-inputJiri Kosina
We have to ignore all non-LED usages in output fields if the report descriptor of the device specifies any. If we don't do so, the devices which contain the same usages both in input and output reports with different parameters will mess things up. In hid-input, we currently care only for the input usages, with exception for LEDs. All other output usages should be properly handled by appropriate force-feedback driver.

2007-10-14HID: add support for Microsoft Natural Ergonomic Keyboard 4000Jiri Kosina
This keyboard emits a few usages that are not handled properly by hid-input. The usages from MSVENDOR page are colliding with Chicony Tactical Pad device, so we have to distinguish in runtime. Ugly ... Also, the buttons 1-5 have to be handled in a non-standard way, as they are emitted by the keyboard in a bitfield-like fashion, but the field is not presented as bit-field by the keyboard. The keys can't be pressed simultaneously, so the handling we have is correct. This patch also extends hid_keyboard[] with KPLeftParenthesis and KPRightParenthesis as defined by Keyboard page in HUT 1.12. The corresponding usages are also emitted by this keyboard.

2007-10-14UBI: fix atomic LEB change problemsArtem Bityutskiy
When the UBI device is nearly full, i.e. all LEBs are mapped, we have only one spare LEB left - the one we reserved for WL purposes. Well, I do not count the LEBs which were reserved for bad PEB handling - suppose NOR flash for simplicity. If an "atomic LEB change operation" is run, and the WL unit is moving a LEB, we have no spare LEBs to finish the operation and fail, which is not good. Moreover, if there are 2 or more simultanious "atomic LEB change" requests, only one of them has chances to succeed, the other will fail with -ENOSPC. Not good either. This patch does 2 things: 1. Reserves one PEB for the "atomic LEB change" operation. 2. Serealize the operations so that only on of them may run at a time (by means of a mutex).

2007-10-14UBI: do not use vmalloc on I/O pathArtem Bityutskiy
Similar reason as in case of the previous patch: it causes deadlocks if a filesystem with writeback support works on top of UBI. So pre-allocate needed buffers when attaching MTD device. We also need mutexes to protect the buffers, but they do not cause much contantion because they are used in recovery, torture, and WL copy routines, which are called seldom.

2007-10-14UBI: don't use array index before testing if it is negativeJesper Juhl
I can't find anything guaranteeing that 'ubi_num' cannot be <0 in drivers/mtd/ubi/kapi.c::ubi_open_volume(), and in fact the code even tests for that and errors out if so. Unfortunately the test for "ubi_num < 0" happens after we've already used 'ubi_num' as an array index - bad thing to do if it is negative. This patch moves the test earlier in the function and then moves the indexing using that variable after the check.

2007-10-13[SPARC64]: Kill ugly __bucket() macro.David S. Miller
All the users go through virt_irq_to_bucket() and essentially want to go from a virt_irq to an INO, but we have a way to do that already via virt_to_real_irq_table[].dev_ino.

2007-10-13[SPARC64]: Use sun4v VIRQ interfaces as intended.David S. Miller
We were simply concatenating the devhandle and devino and using that as the cookie, which defeats the entire purpose of the VIRQ hypervisor interfaces. Now that we use physical addresses for the INO buckets, we can allocate them dynamically for VIRQs and encode the cookies as ~__pa(bucket). This allows us to test for and decode the cookie with a simple: brlz $reg1, 1f xnor $reg1, %g0, $reg2 sequence. This works because bit 64 is never set in traditional INO vectors, and it is also never set in a physical address. So xnor'ing the physical address of the bucket always gives us a negative number, and thus a unique condition we can test cheaply. Inspired by ideas from Greg Onufer. Signed-off-by: David S. Miller <davem@davemloft.net>

2007-10-13[SPARC64]: Make IVEC pointers 64-bit.David S. Miller
Currently we chain IVEC entries using 32-bit "pointers" because we know that the ivector_table is in the main kernel image, thus below 4GB. This uses proper 64-bit pointers instead. Whilst this bloats up the kernel image size, this sets the infrastructure necessary to significantly shrink the kernel size by using physical addresses and dynamically allocating the ivector table.

2007-10-13[SPARC64]: Consolidate MSI support code.David S. Miller
This also makes us use the MSI queues correctly. Each MSI queue is serviced by a normal sun4u/sun4v INO interrupt handler. This handler runs the MSI queue and dispatches the virtual interrupts indicated by arriving MSIs in that MSI queue. All of the common logic is placed in pci_msi.c, with callbacks to handle the PCI controller specific aspects of the operations. This common infrastructure will make it much easier to add MSG support.

Thanks to Tom Callaway for the excellent bug report and test case. sys_ipc() has several problems, most to due with semaphore call handling: 1) 'err' return should be a 'long' 2) "union semun" is passed in a register on 64-bit compared to 32-bit which provides it on the stack and therefore by reference 3) Second and third arguments to SEMCTL are swapped compared to 32-bit.

2007-10-13[SPARC32]: Add irqflags.h to sparc32 and use it from generic code.Robert Reif
Added asm-sparc/irqflags.h and moved irq related code from system.h to it. Renamed local_irq functions to raw_local_irq in irq.c. Modified system.h to include linux/irqflags.h which includes asm/irqflags.h. Added TRACE_IRQFLAGS_SUPPORT to Kconfig.debug. This is the first step in adding IRQ-flags state tracing as outlined in Documentation/irqflags-tracing.txt. These changes should be harmless because they just move things around and rename them. The next step is making the lowlevel entry code modifications which to be honest are beyond my capabilities at this point. Boot tested on an ss20 running an SMP kernel.
