2014-09-10drm: add driver->set_busid() callbackDavid Herrmann30-9/+59
One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe). Therefore, we create two different drivers for each platform during module_init() and set the set_busid() callback respectively.

2014-09-10drm: Use vblank_disable_and_save in drm_vblank_cleanup()Mario Kleiner1-1/+5
Calling vblank_disable_fn() will cause that function to no-op if !dev->vblank_disable_allowed for some kms drivers, e.g., on nouveau-kms. This can cause the gpu vblank irq's to not get disabled before freeing the dev->vblank array, so if a vblank irq fires and calls into drm_handle_vblank() after drm_vblank_cleanup() completes, it will cause use-after-free access to dev->vblank array. Call vblank_disable_and_save unconditionally, so vblank irqs are guaranteed to be off, before we delete the data structures on which they operate.

It is hardly possible to review the drmP.h includes, anymore. Order them alphabetically, linux/ first, then asm/ and then local drm/ includes. Since a long time ago, kernel headers have been converted to include required headers themselves. No-one cares whether that means the compiler has to include a header multiple times.

2014-09-10Input: synaptics - add support for ForcePadsDmitry Torokhov2-16/+63
ForcePads are found on HP EliteBook 1040 laptops. They lack any kind of physical buttons, instead they generate primary button click when user presses somewhat hard on the surface of the touchpad. Unfortunately they also report primary button click whenever there are 2 or more contacts on the pad, messing up all multi-finger gestures (2-finger scrolling, multi-finger tapping, etc). To cope with this behavior we introduce a delay (currently 50 msecs) in reporting primary press in case more contacts appear.

This patch removes calls to s3c_hsotg_phy_disable from s3c_hsotg_remove and s3c_hsotg_udc_stop. s3c_hsotg_udc_stop is called from udc-core.c only after usb_gadget_disconnect, which in turn calls s3c_hsotg_pullup, which already calls s3c_hsotg_phy_disable. s3c_hsotg_remove must be called only after udc_stop, so there is no point in disabling phy once again there.

charged" This reverts commit 232de5143790 ("ACPI / battery: fix wrong value of capacity_now reported when fully charged") There is nothing wrong or unexpected about 'capacity_now' increasing above the last 'full_charge_capacity' value. Different charging cycles will cause 'full_charge_capacity' to vary, both up and down. Good battery firmwares will update 'full_charge_capacity' when the current charging cycle is complete, increasing it if necessary. It might even go above 'design_capacity' on a fresh and healthy battery. Capping 'capacity_now' to 'full_charge_capacity' is plain wrong, and printing a warning if this doesn't happen to match the 'design_capacity' is both annoying and terribly wrong. This results in bogus warnings on perfectly working systems/firmwares: [Firmware Bug]: battery: reported current charge level (39800) is higher than reported maximum charge level (39800). and wrong values being reported for 'capacity_now' and 'full_charge_capacity' after the warning has been triggered.

2014-09-09powerpc: Make CONFIG_FHANDLE=y for all 64 bit powerpc defconfigsCyril Bur11-0/+11
CONFIG_FHANDLE is a requirement for systemd and with the increasing uptake of systemd within distros it makes sense for 64 bit defconfigs to include it. Signed-off-by: Cyril Bur <cyril.bur@au1.ibm.com>
2014-09-09powerpc: use machine_subsys_initcall() for opal_hmi_handler_init()Li Zhong1-1/+2
As opal_message_init() uses machine_early_initcall(powernv, ), and opal_hmi_handler_init() depends on that early initcall, so it also needs use machine_* to check the machine_id. Signed-off-by: Li Zhong <zhong@linux.vnet.ibm.com>
2014-09-09powerpc/perf: Fix ABIv2 kernel backtracesAnton Blanchard2-1/+8
ABIv2 kernels are failing to backtrace through the kernel. An example: 39.30% readseek2_proce [kernel.kallsyms] [k] find_get_entry | --- find_get_entry __GI___libc_read The problem is in valid_next_sp() where we check that the new stack pointer is at least STACK_FRAME_OVERHEAD below the previous one. ABIv1 has a minimum stack frame size of 112 bytes consisting of 48 bytes and 64 bytes of parameter save area. ABIv2 changes that to 32 bytes with no paramter save area. STACK_FRAME_OVERHEAD is in theory the minimum stack frame size, but we over 240 uses of it, some of which assume that it includes space for the parameter area. We need to work through all our stack defines and rationalise them but let's fix perf now by creating STACK_FRAME_MIN_SIZE and using in valid_next_sp(). This fixes the issue: 30.64% readseek2_proce [kernel.kallsyms] [k] find_get_entry | --- find_get_entry pagecache_get_page generic_file_read_iter new_sync_read vfs_read sys_read syscall_exit __GI___libc_read Cc: stable@vger.kernel.org # 3.16+ Reported-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Anton Blanchard <anton@samba.org>
