2018-08-15PCI/AER: Don't clear AER bits if error handling is Firmware-FirstAlexandru Gagniuc1-0/+9
If the platform requests Firmware-First error handling, firmware is responsible for reading and clearing AER status bits. If OSPM also clears them, we may miss errors. See ACPI v6.2, sec 18.3.2.5 and 18.4. This race is mostly of theoretical significance, as it is not easy to reasonably demonstrate it in testing.

2018-08-15IB/core: Change filter function return type from int to boolParav Pandit2-31/+43
Filter functions returns either 0 or 1, therefore better change their return type from int to bool to reflect the same. Additionally some filter functions have suffix of _filter some doesn't.

2018-08-15IB/core: Add default GIDs of the bond master netdevParav Pandit1-29/+59
Currently following issues exist: 1. Default GIDs of the lower (slave) netdevice if the bond netdevice is added. Rather default GID should be of bond master netdevice. 2. Due to this, when failover event occurs FAILOVER event handler attempts to delete the GID of the upper device and tries to add the default GID of the lower device. This is incorrect behavior. To have simple and correct code: (a) Split default GIDs addition out of add_netdev_ips(). This allows easier removal in future if RoCE default GIDs are removed. (b) Add default GIDs of the bond master device by using right filter and callback function. (c) Remove unused function enum_netdev_default_gids().

2018-08-15IB/core: Delete lower netdevice default GID entries in bonding scenarioParav Pandit1-9/+62
When NETDEV_CHANGEUPPER event occurs, lower device is not yet established as slave of the master, and when upper device is bond device, default GID entries not deleted. Due to this, when bond device is fully configured, default GID entries of bond device cannot be added as default GID entries are occupied by the lower netdevice. This is incorrect. Default GID entries should really be of bond netdevice because in all RoCE GIDs (default or IP), MAC address of the bond device will be used. It is confusing to have default GID of netdevice which is not really used for any purpose. Therefore, as first step, implement (a) filter function which filters if a CHANGEUPPER event netdevice and associated upper device is master device or not. (b) callback function which deletes the default GIDs of lower (event netdevice).

Like the NFP4000 and NFP6000, the NFP5000 as an erratum where reading/ writing to PCI config space addresses above 0x600 can cause the NFP to generate PCIe completion timeouts. Limit the NFP5000's PF's config space size to 0x600 bytes as is already done for the NFP4000 and NFP6000. The NFP5000's VF is 0x6003 (PCI_DEVICE_ID_NETRONOME_NFP6000_VF), the same device ID as the NFP6000's VF. Thus, its config space is already limited by the existing use of quirk_nfp6000().

Currently bond_delete_netdev_default_gids() is called by two callers. (a) del_netdev_default_ips_join() (b) del_netdev_default_ips() Both above functions changes the argument order while calling bond_delete_netdev_default_gids(). This required silly del_netdev_default_ips() wrapper. Additionally, del_netdev_default_ips() deletes default GIDs not IP based GIDs. del_netdev_default_ips() having _ips suffix is confusing. Therefore, get rid of confusing del_netdev_default_ips() and simplify bond_delete_netdev_default_gids() to follow same argument order as its caller.

2018-08-15ubi: expose the volume CRC check skip flagQuentin Schulz2-0/+14
Now that we have the logic for skipping CRC check for static UBI volumes in the core, let's expose it to users. This makes use of a padding byte in the volume description data structure as a flag. This flag only tell for now whether we should skip the CRC check of a volume. This checks the UBI volume for which we are trying to skip the CRC check is static. Let's also make sure that the flags passed to verify_mkvol_req are valid. We voluntarily do not take into account the skip_check flag in vol_cdev_write() as we want to make sure what we wrote was correctly written.

2018-08-15ubi: provide a way to skip CRC checksQuentin Schulz5-1/+23
Some users of static UBI volumes implement their own integrity check, thus making the volume CRC check done at open time useless. For instance, this is the case when one use the ubiblock + dm-verity + squashfs combination, where dm-verity already checks integrity of the block device but this time at the block granularity instead of verifying the whole volume. Skipping this test drastically improves the boot-time.

2018-08-14ACPICA: Clear status of all events when entering sleep statesRafael J. Wysocki1-8/+3
Commit fa85015c0d95 (ACPICA: Clear status of all events when entering S5) made the sleep state entry code in ACPICA clear the status of all ACPI events when entering S5 to fix a functional regression reported against commit 18996f2db918 (ACPICA: Events: Stop unconditionally clearing ACPI IRQs during suspend/resume). However, it is reported now that the regression also affects system states other than S5 on some systems and causes them to wake up from sleep prematurely. For this reason, make the code in question clear the status of all ACPI events when entering all sleep states (in addition to S5) to avoid the premature wakeups (this may cause some wakeup events to be missed in theory, but the likelihood of that is small and the change here simply restores the previous behavior of the code).

2018-08-14ACPICA: acpi_exec: fixing -fi optionErik Schmauss4-9/+57
Field elements listed in the init file used to be initialized after the table load and before executing module-level code blocks. The recent changes in module-level code mean that the table load becomes a method execution. If fields are used within module-level code and we are executing with -fi option, then these values are populated after the table has finished loading. This commit changes the initialization of objects listed in the init file so that field unit values are populated during the table load.
