2009-08-10PM / Driver Core: Kill dev_pm_ops platform warning for nowMagnus Damm
Commit 783ea7d4eeefe895f2731fe73ac951e94418927b (Driver Core: Rework platform suspend/resume, print warning) added a warning message printed for platform drivers that use the legacy PM callbacks rather than struct dev_pm_ops. Unfortunately, this resulted in some confusion and made some people try to convert drivers by replacing the old callbacks with struct dev_pm_ops in automatic way, which generally is not a good idea. Remove the platform device runtime dev_pm_ops warning for now, because it's annoying to users and it's not really necessary right now.

2009-08-10pty: fix data loss when stopped (^S/^Q)Linus Torvalds
Commit d945cb9cc ("pty: Rework the pty layer to use the normal buffering logic") dropped the test for 'tty->stopped' in pty_write_room(), which then causes the n_tty line discipline thing to not throttle the data properly when the tty is stopped. So instead of pausing the write due to the tty being stopped, the ldisc layer would go ahead and push it down to the pty. The pty write() routine would then refuse to take the data (because it _did_ check 'stopped'), and the data wouldn't actually be written. This whole stopped test should eventually be moved into the tty ldisc layer rather than have low-level tty drivers care about these things, but right now the fix is to just re-instate the missing pty 'stopped' handling.

2009-08-09drm: When adding probed modes, preserve duplicate mode typesKeith Packard
The code which takes probed modes and adds them to a connector eliminates duplicate modes by comparing them using drm_mode_equal. That function doesn't consider the type bits, which means that any modes which differ only in the type field will be lost. One of the bits in the mode->type field is the DRM_MODE_TYPE_PREFERRED bit. If the mode with that bit is lost, then higher level code will not know which mode to select, causing a random mode to be used instead. This patch simply merges the two mode type bits together; that seems reasonable to me, but perhaps only a subset of the bits should be used? None of these can be user defined as they all come from looking at just the hardware. Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-08-07USB: EHCI: fix two new bugs related to Clear-TT-BufferAlan Stern
This patch (as1273) fixes two(!) bugs introduced by the new Clear-TT-Buffer implementation in ehci-hcd. It is now possible for an idle QH to have some URBs on its queue -- this will happen if a Clear-TT-Buffer is pending for the QH's endpoint. Consequently we should not issue a warning when someone tries to unlink an URB from an idle QH; instead we should process the request immediately. The refcounts for QHs could get messed up, because submit_async() would increment the refcount when calling qh_link_async() and qh_link_async() would then refuse to link the QH into the schedule if a Clear-TT-Buffer was pending. Instead we should increment the refcount only when the QH actually is added to the schedule. The current code tries to be clever by leaving the refcount alone if an unlink is immediately followed by a relink; the patch changes this to an unconditional decrement and increment (although they occur in the opposite order).

access_ok() checks must be done on every part of the userspace structure that is accessed. If access_ok() on one part of the struct succeeded, it does not imply it will succeed on other parts of the struct. (Does depend on the architecture implementation of access_ok()).

2009-08-07fbcon: don't use vc_resize() on initializationJohannes Weiner
Catalin and kmemleak spotted a leak of a VC screen buffer in vc_allocate() due to the following chain of events: vc_allocate() visual_init(init=1) vc->vc_sw->con_init(init=1) fbcon_init() vc_resize() vc->screen_buf = kmalloc() vc->screen_buf = kmalloc() The common way for the VC drivers is to set the screen dimension parameters manually in the init case and only call vc_resize() for !init - which allocates a screen buffer according to the new dimensions. fbcon instead would do vc_resize() unconditionally and afterwards set the dimensions manually (again) for !init - i.e. completely upside down. The vc_resize() allocated buffer would then get lost by vc_allocate() allocating a fresh one. Use vc_resize() only for actual resizing to close the leak. Set the dimensions manually only in initialization mode to remove the redundant setting in resize mode.

2009-08-07fbcon: fix rotate upside down crashStefani Seibold
Fix the rotate_ud() function not to crash in case of a font which has not a width of multiple by 8: The inner loop of the font pixel copy should not access a bit outside the font memory area. Subtract the shift offset from the font width will prevent this.

2009-08-07PCI hotplug: SGI hotplug: do not use hotplug_slot_attrKenji Kaneshige
By the pci slot changes, callbacks of attributes under slot directory (/sys/bus/pci/slots) had been changed to get the pointer to struct pci_slot instead of struct hotplug_slot. So the path_show() that assumes the parameter is a pointer to struct hotplug_slot seems broken.

2009-08-07PCI hotplug: SGI hotplug: fix build failureKenji Kaneshige
The commit bd3d99c17039fd05a29587db3f4a180c48da115a ("PCI: Remove untested Electromechanical Interlock (EMI) support in pciehp."), which removes the definition of "struct hotplug_slot_attr", broke SGI hotplug driver. By this commit, we get the following compile error. drivers/pci/hotplug/sgi_hotplug.c:106: error: variable 'sn_slot_path_attr' has initializer but incomplete type drivers/pci/hotplug/sgi_hotplug.c:106: error: unknown field 'attr' specified in initializer drivers/pci/hotplug/sgi_hotplug.c:106: error: extra brace group at end of initializer drivers/pci/hotplug/sgi_hotplug.c:106: error: (near initialization for 'sn_slot_path_attr') drivers/pci/hotplug/sgi_hotplug.c:106: warning: excess elements in struct initializer drivers/pci/hotplug/sgi_hotplug.c:106: warning: (near initialization for 'sn_slot_path_attr') drivers/pci/hotplug/sgi_hotplug.c:106: error: unknown field 'show' specified in initializer drivers/pci/hotplug/sgi_hotplug.c:106: warning: excess elements in struct initializer drivers/pci/hotplug/sgi_hotplug.c:106: warning: (near initialization for 'sn_slot_path_attr') drivers/pci/hotplug/sgi_hotplug.c: In function 'sn_hp_destroy': drivers/pci/hotplug/sgi_hotplug.c:203: error: invalid use of undefined type 'struct hotplug_slot_attribute' drivers/pci/hotplug/sgi_hotplug.c: In function 'sn_hotplug_slot_register': drivers/pci/hotplug/sgi_hotplug.c:655: error: invalid use of undefined type 'struct hotplug_slot_attribute' This patch fixes this regression by adding the definition of struct hotplug_slot_attr into sgi_hotplug.c.

2009-08-06intel-iommu: Fix enabling snooping feature by mistakeSheng Yang
Two defects work together result in KVM device passthrough randomly can't work: 1. iommu_snooping is not initialized to zero when vm_iommu_init() called. So it is possible to get a random value. 2. One line added by commit 2c2e2c38("IOMMU Identity Mapping Support") change the code path, let it bypass domain_update_iommu_cap(), as well as missing the increment of domain iommu reference count. The latter is also likely to cause a leak of domains on repeated VMM assignment and deassignment.

The Prestigio 157, an old no-name clone laptop uses input keys very similar to the Wistron 1557/MS2141 with the addition of BIOS-controlled wireless radio frequency kill switch. This patch adds support for the RF kill switch control and adds manual identification of the model. The Prestigio does not expose any recognisable identity via dmidecode and so requires manual selection at module init using force=1 keymap=prestigio Signed-off-by: TJ <ubuntu@tjworld.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2009-08-05intel-iommu: Correct sglist size calculation.Fenghua Yu
In domain_sg_mapping(), use aligned_nrpages() instead of hand-coded rounding code for calculating the size of each sg elem. This means that on IA64 we correctly round up to the MM page size, not just to the VT-d page size. Also remove the incorrect mm_to_dma_pfn() when intel_map_sg() calls domain_sg_mapping() -- the 'size' variable is in VT-d pages already.
