2016-03-29ixgbe: Store VXLAN port number in network orderAlexander Duyck2-49/+20
The VXLAN port number should be stored in network order instead of in host order as it is accessed from the hot-path in ATR. This way we can avoid having to do any byte swaps in order to validate the port number. I moved the vxlan_port value into a hole in the read-mostly region of the adapter struct. This way it should be in a warm cache-line instead of in some isolated region in memory when it needs to be accessed. In addition I went through and stripped a bunch of unneeded ifdef flags since having an extra variable present doesn't really hurt anything and makes the code easier to read. I also went through and dropped the NETIF_F_RXCSUM flag which was being set in hw_encap_features but provides no value as the flag is not evaluated in the Rx path.

2016-03-29ixgbe: Fix for RAR0 not being set to default MAC addrTushar Dave1-0/+2
commit c9f53e63c208 ("ixgbe: Refactor MAC address configuration code") introduced code that doesn't set HW register RAR0 to default mac address but FF:FF:FF:FF:FF:FF. Due to this, ixgbe HW discards all incoming packets that doesn't have destination mac address equals to FF:FF:FF:FF:FF:FF. This commit sets RAR0 correctly to default HW mac address.

2016-03-28drm/rockchip: dw_hdmi: Don't call platform_set_drvdata()Douglas Anderson1-2/+0
The Rockchip dw_hdmi driver just called platform_set_drvdata() to get your hopes up that maybe, somehow, you'd be able to retrieve the 'struct rockchip_hdmi' from a pointer to the 'struct device'. You can't. When we call dw_hdmi_bind() the main driver calls dev_set_drvdata(), which clobbers our setting. Let's just remove the platform_set_drvdata() to avoid dashing people's hopes.

2016-03-28drm/rockchip: vop: Fix vop crtc cleanupDouglas Anderson1-3/+24
This fixes a few problems in the vop crtc cleanup (handling error paths and cleanup upon exit): * The vop_create_crtc() error path had an unsafe version of the iterator used for iterating over all planes (though it was destroying planes in the iterator so should have used the safe version) * vop_destroy_crtc() - wasn't calling vop_plane_destroy(), which made slub_debug unhappy, at least if we ended up running this due to a deferred probe. * In vop_create_crtc() if we were missing the "port" device tree node we would fail but not return an error (found by code inspection).

2016-03-28drm/rockchip: dw_hdmi: Call drm_encoder_cleanup() in error pathDouglas Anderson1-1/+10
The drm_encoder_cleanup() was missing both from the error path of dw_hdmi_rockchip_bind(). This caused a crash when slub_debug was enabled and we ended up deferring probe of HDMI at boot. This call isn't needed from unbind() because if dw_hdmi_bind() returns no error then it takes over the job of freeing the encoder (in dw_hdmi_unbind).

2016-03-26ACPI / processor: Request native thermal interrupt handling via _OSCSrinivas Pandruvada3-0/+61
There are several reports of freeze on enabling HWP (Hardware PStates) feature on Skylake-based systems by the Intel P-states driver. The root cause is identified as the HWP interrupts causing BIOS code to freeze. HWP interrupts use the thermal LVT which can be handled by Linux natively, but on the affected Skylake-based systems SMM will respond to it by default. This is a problem for several reasons: - On the affected systems the SMM thermal LVT handler is broken (it will crash when invoked) and a BIOS update is necessary to fix it. - With thermal interrupt handled in SMM we lose all of the reporting features of the arch/x86/kernel/cpu/mcheck/therm_throt driver. - Some thermal drivers like x86-package-temp depend on the thermal threshold interrupts signaled via the thermal LVT. - The HWP interrupts are useful for debugging and tuning performance (if the kernel can handle them). The native handling of thermal interrupts needs to be enabled because of that. This requires some way to tell SMM that the OS can handle thermal interrupts. That can be done by using _OSC/_PDC in processor scope very early during ACPI initialization. The meaning of _OSC/_PDC bit 12 in processor scope is whether or not the OS supports native handling of interrupts for Collaborative Processor Performance Control (CPPC) notifications. Since on HWP-capable systems CPPC is a firmware interface to HWP, setting this bit effectively tells the firmware that the OS will handle thermal interrupts natively going forward. For details on _OSC/_PDC refer to: http://www.intel.com/content/www/us/en/standards/processor-vendor-specific-acpi-specification.html To implement the _OSC/_PDC handshake as described, introduce a new function, acpi_early_processor_osc(), that walks the ACPI namespace looking for ACPI processor objects and invokes _OSC for them with bit 12 in the capabilities buffer set and terminates the namespace walk on the first success. Also modify intel_thermal_interrupt() to clear HWP status bits in the HWP_STATUS MSR to acknowledge HWP interrupts (which prevents them from firing continuously).

2016-03-25drivers/memstick/host/r592.c: avoid gcc-6 warningArnd Bergmann1-2/+1
The r592 driver relies on behavior of the DMA mapping API that is normally observed but not guaranteed by the API. Instead it uses a runtime check to fail transfers if the API ever behaves When CONFIG_NEED_SG_DMA_LENGTH is not set, one of the checks turns into a comparison of a variable with itself, which gcc-6.0 now warns about: drivers/memstick/host/r592.c: In function 'r592_transfer_fifo_dma': drivers/memstick/host/r592.c:302:31: error: self-comparison always evaluates to false [-Werror=tautological-compare] (sg_dma_len(&dev->req->sg) < dev->req->sg.length)) { ^ The check itself is not a problem, so this patch just rephrases the condition in a way that gcc does not consider an indication of a mistake. We already know that dev->req->sg.length was initially R592_LFIFO_SIZE, so we can compare it to that constant again.

2016-03-25libceph: enable large, variable-sized OSD requestsIlya Dryomov1-2/+0
Turn r_ops into a flexible array member to enable large, consisting of up to 16 ops, OSD requests. The use case is scattered writeback in cephfs and, as far as the kernel client is concerned, 16 is just a made up number. r_ops had size 3 for copyup+hint+write, but copyup is really a special case - it can only happen once. ceph_osd_request_cache is therefore stuffed with num_ops=2 requests, anything bigger than that is allocated with kmalloc(). req_mempool is backed by ceph_osd_request_cache, which means either num_ops=1 or num_ops=2 for use_mempool=true - all existing users (ceph_writepages_start(), ceph_osdc_writepages()) are fine with that.

2016-03-25Revert "ppdev: use new parport device model"Linus Torvalds1-20/+5
This reverts commit e7223f18603374d235d8bb0398532323e5f318b9. It causes problems when a ppdev tries to register before the parport driver has been registered with the device model. That will trigger the BUG_ON(!drv->bus->p); at drivers/base/driver.c:153. The call chain is kernel_init -> kernel_init_freeable -> do_one_initcall -> ppdev_init -> __parport_register_driver -> driver_register *BOOM* Reported-by: kernel test robot <fengguang.wu@intel.com> Reported-by: Ross Zwisler <zwisler@gmail.com> Reported-by: Petr Mladek <pmladek@suse.com> Cc: Sudip Mukherjee <sudipm.mukherjee@gmail.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
