2009-06-14keyboard: advertise KT_DEAD2 extended diacriticalsSamuel Thibault
In addition to KT_DEAD which has limited support for diacriticals, there is KT_DEAD2 that can support 256 criticals, so let's advertise it in <linux/keyboard.h>. This lets userland know abut the drivers/char/keyboard.c function k_dead2, which supports more than the few trivial ones that k_dead supports.

2009-06-13i2c-ocores: Can add I2C devices to the busRichard Röjfors
There is sometimes a need for the ocores driver to add devices to the bus when installed. i2c_register_board_info can not always be used, because the I2C devices are not known at an early state, they could for instance be connected on a I2C bus on a PCI device which has the Open Cores IP. i2c_new_device can not be used in all cases either since the resulting bus nummer might be unknown. The solution is the pass a list of I2C devices in the platform data to the Open Cores driver. This is useful for MFD drivers.

2009-06-12PM: Add empty suspend/resume device irq functionsHeiko Carstens
git commit 0a0c5168 "PM: Introduce functions for suspending and resuming device interrupts" introduced some helper functions. However these functions are only available for architectures which support GENERIC_HARDIRQS. Other architectures will see this build error: drivers/built-in.o: In function `sysdev_suspend': (.text+0x15138): undefined reference to `check_wakeup_irqs' drivers/built-in.o: In function `device_power_up': (.text+0x1cb66): undefined reference to `resume_device_irqs' drivers/built-in.o: In function `device_power_down': (.text+0x1cb92): undefined reference to `suspend_device_irqs' To fix this add some empty inline functions for !GENERIC_HARDIRQS.

2009-06-12PM/Hibernate: Move NVS routines into a seperate file (v2).Cornelia Huck
The *_nvs_* routines in swsusp.c make use of the io*map() functions, which are only provided for HAS_IOMEM, thus breaking compilation if HAS_IOMEM is not set. Fix this by moving the *_nvs_* routines into hibernate_nvs.c, which is only compiled if HAS_IOMEM is set.

2009-06-12PM core: rename suspend and resume functionsAlan Stern
This patch (as1241) renames a bunch of functions in the PM core. Rather than go through a boring list of name changes, suffice it to say that in the end we have a bunch of pairs of functions: device_resume_noirq dpm_resume_noirq device_resume dpm_resume device_complete dpm_complete device_suspend_noirq dpm_suspend_noirq device_suspend dpm_suspend device_prepare dpm_prepare in which device_X does the X operation on a single device and dpm_X invokes device_X for all devices in the dpm_list. In addition, the old dpm_power_up and device_resume_noirq have been combined into a single function (dpm_resume_noirq). Lastly, dpm_suspend_start and dpm_resume_end are the renamed versions of the former top-level device_suspend and device_resume routines.

2009-06-12PM: Rename device_power_down/up()Magnus Damm
Rename the functions performing "_noirq" dev_pm_ops operations from device_power_down() and device_power_up() to device_suspend_noirq() and device_resume_noirq(). The new function names are chosen to show that the functions are responsible for calling the _noirq() versions to finalize the suspend/resume operation. The current function names do not perform power down/up anymore so the names may be misleading. Global function renames: - device_power_down() -> device_suspend_noirq() - device_power_up() -> device_resume_noirq() Static function renames: - suspend_device_noirq() -> __device_suspend_noirq() - resume_device_noirq() -> __device_resume_noirq() Signed-off-by: Magnus Damm <damm@igel.co.jp> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Acked-by: Len Brown <lenb@kernel.org> Signed-off-by: Rafael J.

2009-06-13fb: add support of LCD display controller on pxa168/910 (base layer)Lennert Buytenhek
This driver is originally written by Lennert, modified by Green to be feature complete, and ported by Jun Nie and Kevin Liu for pxa168/910 processors. The patch adds support for the on-chip LCD display controller, it currently supports the base (graphics) layer only.

2009-06-12slab,slub: don't enable interrupts during early bootPekka Enberg
As explained by Benjamin Herrenschmidt: Oh and btw, your patch alone doesn't fix powerpc, because it's missing a whole bunch of GFP_KERNEL's in the arch code... You would have to grep the entire kernel for things that check slab_is_available() and even then you'll be missing some. For example, slab_is_available() didn't always exist, and so in the early days on powerpc, we used a mem_init_done global that is set form mem_init() (not perfect but works in practice). And we still have code using that to do the test. Therefore, mask out __GFP_WAIT, __GFP_IO, and __GFP_FS in the slab allocators in early boot code to avoid enabling interrupts.

2009-06-12lguest: remove obsolete LHREQ_BREAK callRusty Russell
We no longer need an efficient mechanism to force the Guest back into host userspace, as each device is serviced without bothering the main Guest process (aka. the Launcher). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-06-12lguest: use eventfds for device notificationRusty Russell
Currently, when a Guest wants to perform I/O it calls LHCALL_NOTIFY with an address: the main Launcher process returns with this address, and figures out what device to run. A far nicer model is to let processes bind an eventfd to an address: if we find one, we simply signal the eventfd.

2009-06-12lguest: improve interrupt handling, speed up stream networkingRusty Russell
lguest never checked for pending interrupts when enabling interrupts, and things still worked. However, it makes a significant difference to TCP performance, so it's time we fixed it by introducing a pending_irq flag and checking it on irq_restore and irq_enable. These two routines are now too big to patch into the 8/10 bytes patch space, so we drop that code. Note: The high latency on interrupt delivery had a very curious effect: once everything else was optimized, networking without GSO was faster than networking with GSO, since more interrupts were sent and hence a greater chance of one getting through to the Guest! Note2: (Almost) Closing the same loophole for iret doesn't have any measurable effect, so I'm leaving that patch for the moment. Before: 1GB tcpblast Guest->Host: 30.7 seconds 1GB tcpblast Guest->Host (no GSO): 76.0 seconds After: 1GB tcpblast Guest->Host: 6.8 seconds 1GB tcpblast Guest->Host (no GSO): 27.8 seconds Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-06-12virtio: indirect ring entries (VIRTIO_RING_F_INDIRECT_DESC)Mark McLoughlin
Add a new feature flag for indirect ring entries. These are ring entries which point to a table of buffer descriptors. The idea here is to increase the ring capacity by allowing a larger effective ring size whereby the ring size dictates the number of requests that may be outstanding, rather than the size of those requests. This should be most effective in the case of block I/O where we can potentially benefit by concurrently dispatching a large number of large requests. Even in the simple case of single segment block requests, this results in a threefold increase in ring capacity.

2009-06-12virtio: teach virtio_has_feature() about transport featuresMark McLoughlin
Drivers don't add transport features to their table, so we shouldn't check these with virtio_check_driver_offered_feature(). We could perhaps add an ->offered_feature() virtio_config_op, but that perhaps that would be overkill for a consitency check like this.

2009-06-12perf_counter: Add forward/backward attribute ABI compatibilityPeter Zijlstra
Provide for means of extending the perf_counter_attr in a 'natural' way. We allow growing the structure by appending fields at the end by specifying the full structure size inside it. When a new kernel sees a smaller (old) structure, it will 0 pad the tail. When an old kernel sees a larger (new) structure, it will verify the tail consists of 0s, otherwise fail. If we fail due to a size-mismatch, we return -E2BIG and write the kernel's native attribe size back into the provided structure. Furthermore, add some attribute verification, so that we'll fail counter creation when unknown bits are present (PERF_SAMPLE, PERF_FORMAT, or in the __reserved fields). (This ABI detail is introduced while keeping the existing syscall ABI.)
