2018-12-18drm/etnaviv: replace header include with forward declarationLucas Stach
The etnaviv_gpu header only needs to know about the pointer types, so replace by a forward declaration and only include the headers where needed. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Reviewed-by: Christian Gmeiner <christian.gmeiner@gmail.com>
2018-12-18drm/etnaviv: remove unnecessary local irq disableLucas Stach
The only event function that is called from IRQ context is event_free, which is already using atomic bitmap operations, so we can avoid taking the event spinlock in this function completely. As other the other functions still using the event spinlock are all called from normal process context, we can avoid disabling IRQs while holding the spinlock.

2018-12-18pinctrl: sh-pfc: Make pinmux_cfg_reg.var_field_width[] variable-lengthGeert Uytterhoeven
pinmux_cfg_reg.var_field_width[] is actually a variable-length array, terminated by a zero, and counting at most r_width entries. Usually the number of entries is much smaller than r_width, so the ability to catch bugs at compile time through an "excess elements in array initializer" warning is fairly limited. Hence make the array variable-length, decreasing kernel size slightly. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Simon Horman <horms+renesas@verge.net.au>
2018-12-18pinctrl: sh-pfc: Print actual field width for variable-width fieldsGeert Uytterhoeven
The debug code in sh_pfc_write_config_reg() prints the width of the field being modified. However, registers with a variable-width field layout are identified by pinmux_cfg_reg.field_width being zero, hence zeroes are printed instead of the actual field widths. Fix this by printing the Hamming weight of the field mask instead, which is correct for both fixed-width and variable-width fields.

2018-12-18ACPI: EC / PM: Disable non-wakeup GPEs for suspend-to-idleRafael J. Wysocki
There are systems in which non-wakeup GPEs fire during the "noirq" suspend stage of suspending devices and that effectively prevents the system that tries to suspend to idle from entering any low-power state at all. If the offending GPE fires regularly and often enough, the system appears to be suspended, but in fact it is in a tight loop over "noirq" suspend and "noirq" resume of devices all the time. To prevent that from happening, disable all non-wakeup GPEs except for the EC GPE for suspend-to-idle (the EC GPE is special, because on some systems it has to be enabled for power button wakeup events to be generated as expected).

2018-12-17nfp: flower: fix cb_ident duplicate in indirect block registerJohn Hurley
Previously the identifier used for indirect block callback registry and for block rule cb registry (when done via indirect blocks) was the pointer to the netdev we were interested in receiving updates on. This worked fine if a single app existed that registered one callback per netdev of interest. However, if multiple cards are in place and, in turn, multiple apps, then each app may register the same callback with the same identifier to both the netdev's indirect block cb list and to a block's cb list. This can lead to EEXIST errors and/or incorrect cb deletions. Prevent this conflict by using the app pointer as the identifier for netdev indirect block cb registry, allowing each app to register a unique callback per netdev. For block cb registry, the same app may register multiple cbs to the same block if using TC shared blocks. Instead of the app, use the pointer to the allocated cb_priv data as the identifier here. This means that there can be a unique block callback for each app/netdev combo.

2018-12-17net/mlx5: Continue driver initialization despite debugfs failureLeon Romanovsky
The failure to create debugfs entry is unpleasant event, but not enough to abort drier initialization. Align the mlx5_core code to debugfs design and continue execution whenever debugfs_create_dir() successes or not.

2018-12-17gpio/mmc/of: Respect polarity in the device treeLinus Walleij
The device tree bindings for the MMC card detect and write protect lines specify that these should be active low unless "cd-inverted" or "wp-inverted" has been specified. However that is not how the kernel code has worked. It has always respected the flags passed to the phandle in the device tree, but respected the "cd-inverted" and "wp-inverted" flags such that if those are set, the polarity will be the inverse of that specified in the device tree. Switch to behaving like the old code did and fix the regression.
