2018-06-01staging: mt7621-dts: add missing properties to gpio nodeSergio Paracuellos1-0/+2
In order to let other devices reference the GPIO interrupts if necessary properties 'interrupt-controller' and '#interrupt-cells' becomes necessary. Add both of them to complete gpio device tree node.

2018-06-01staging: mt7621-gpio: change lock place in irq mask and unmask functionsSergio Paracuellos1-4/+2
Functions mediatek_gpio_irq_umask mediatek_gpio_irq_unmask are reading and modifying registers but only the write is being hold. It should be a complete lock instead for those which are type of "read-modify-write". This makes more sense.

2018-06-01staging: mt7621-gpio: fix masks for gpio pinSergio Paracuellos1-5/+6
BIT macro is being used to get mask for gpio's pin which is retrieved using 'hwirq' from struct irq_data. The problem here is that 'hwirq' can be as large as 95, and 1UL << 95 is unlikely to work well. Instead of using BIT macro use a new PIN_MASK macro which takes into account pin and WIDTH of the bank in order to make a proper mask for the gpio pin. Also 'd->hwirq' has been replaced by 'pin' in some places because there was a 'pin' variable in changed functions with the proper value. This improves readability.

2018-06-01staging: mt7621-gpio: use module_platform_driver() instead subsys initcallSergio Paracuellos1-7/+1
The driver's init function don't do anything besides registering the platform driver, and the exit function which is not included in the driver should only do driver unregister. Because of this module_platform_driver() macro could just be used instead of having separate functions. Currently the macro is not being used because the driver is initialized at subsys init call level but this isn't necessary since platform devices are defined in the DT as dependencies so there's no need for init calls order.

2018-06-01staging: mt7621-gpio: rename MTK_MAX_BANK into MTK_BANK_CNTSergio Paracuellos1-5/+5
There are 3 banks of gpios numbered '0' and '1' and '2'. So the maximum bank number is "2". "3" is the count of banks. In order to make the code looks and be correct on checking max allowed gpio's id it makes sense to change the name of this definition. Also there is another definitions which start with the same prefix MKK_BANK_ of the new name so having those with the same prefix makes all preprocessor structure to be the same.

A number of extern struct declarations in p80211types.h were causing checkpatch warnings: "extern prototypes should be avoided in .h files" and "function definition argument 'xxxxxx' should also have an identifier name". This appears to be a result of using a macro to form the declarations and checkpatch consequently misinterpreting the declarations as function prototypes. On checking, the declarations have no corresponding definition in the driver and are not used, so they are removed along with the macro used to construct them, which is not needed elsewhere. After this change, checkpatch reports that p80211types.h has no obvious issues. Signed-off-by: Tim Collier <osdevtc@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-05-31staging: lustre: mdc: excessive memory consumption by the xattr cacheAndrew Perepechko1-10/+13
The refill operation of the xattr cache does not know the reply size in advance, so it makes a guess based on the maxeasize value returned by the MDS. In practice, it allocates 16 KiB for the common case and 4 MiB for the large xattr case. However, a typical reply is just a few hundred bytes. If we follow the conservative approach, we can prepare a single memory page for the reply. It is large enough for any reasonable xattr set and, at the same time, it does not require multiple page memory reclaim, which can be costly. If, for a specific file, the reply is larger than a single page, the client is prepared to handle that and will fall back to non-cached xattr code. Indeed, if this happens often and xattrs are often used to store large values, it makes sense to disable the xattr cache at all since it wasn't designed for such [mis]use.

2018-05-31staging: lustre: acl: increase ACL entries limitationFan Yong8-8/+24
Originally, the limitation of ACL entries is 32, that is not enough for some use cases. In fact, restricting ACL entries count is mainly for preparing the RPC reply buffer to receive the ACL data. So we cannot make the ACL entries count to be unlimited. But we can enlarge the RPC reply buffer to hold more ACL entries. On the other hand, MDT backend filesystem has its own EA size limitation. For example, for ldiskfs case, if large EA enable, then the max ACL size is 1048492 bytes; otherwise, it is 4012 bytes. For ZFS backend, such value is 32768 bytes. With such hard limitation, we can calculate how many ACL entries we can have at most. This patch increases the RPC reply buffer to match such hard limitation. For old client, to avoid buffer overflow because of large ACL data (more than 32 ACL entries), the MDT will forbid the old client to access the file with large ACL data. As for how to know whether it is old client or new, a new connection flag OBD_CONNECT_LARGE_ACL is used for that.

refactor function a bit Driver probe function includes an allocation using devm_kzalloc which is "hidden" a bit inside the declarations. Extract this to a better place to increase readability. Also because we are allocating zeroed memory 'memset' statement is not needed at all. Condition for checking for a valid gpio id is wrong and it should be greater or equal instead of only greater so update to be the good one.

2018-05-25staging: mt7621-gpio: avoid use of globals and use platform_data insteadSergio Paracuellos1-28/+62
Gpio driver have a some globals which can be avoided just using platform_data in a proper form. This commit adds a new struct mtk_data which includes all of those globals setting them using platform_set_drvdata and devm_gpiochip_add_data functions. With this properly set we are able to retrieve driver data along the code using kernel api's so globals are not needed anymore.
