misc: remove redundant 'default n' from Kconfig-s
'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly.
Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not:
... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same:
config FOO bool
config FOO bool default n
With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...

cxl: Export library to support IBM XSL
This patch exports a in-kernel 'library' API which can be called by other drivers to help interacting with an IBM XSL on a POWER9 system.
The XSL (Translation Service Layer) is a stripped down version of the PSL (Power Service Layer) used in some cards such as the Mellanox CX5. Like the PSL, it implements the CAIA architecture, but has a number of differences, mostly in it's implementation dependent registers.
The XSL also uses a special DMA cxl mode, which uses a slightly different init sequence for the CAPP and PHB.

cxl: Add cxl_check_and_switch_mode() API to switch bi-modal cards
Add a new API, cxl_check_and_switch_mode() to allow for switching of bi-modal CAPI cards, such as the Mellanox CX-4 network card.
When a driver requests to switch a card to CAPI mode, use PCI hotplug infrastructure to remove all PCI devices underneath the slot. We then write an updated mode control register to the CAPI VSEC, hot reset the card, and reprobe the card.
As the card may present a different set of PCI devices after the mode switch, use the infrastructure provided by the pnv_php driver and the OPAL PCI slot management facilities to ensure that:
* the old devices are removed from both the OPAL and Linux device trees * the new devices are probed by OPAL and added to the OPAL device tree * the new devices are added to the Linux device tree and probed through the regular PCI device probe path
As such, introduce a new option, CONFIG_CXL_BIMODAL, with a dependency on the pnv_php driver.
Refactor existing code that touches the mode control register in the regular single mode case into a new function, setup_cxl_protocol_area().

cxl: Add mechanism for delivering AFU driver specific events
This adds an afu_driver_ops structure with fetch_event() and event_delivered() callbacks. An AFU driver such as cxlflash can fill this out and associate it with a context to enable passing custom AFU specific events to userspace.
This also adds a new kernel API function cxl_context_pending_events(), that the AFU driver can use to notify the cxl driver that new specific events are ready to be delivered, and wake up anyone waiting on the context wait queue.
The current count of AFU driver specific events is stored in the field afu_driver_events of the context structure.
The cxl driver checks the afu_driver_events count during poll, select, read, etc. calls to check if an AFU driver specific event is pending, and calls fetch_event() to obtain and deliver that event. This way, the cxl driver takes care of all the usual locking semantics around these calls and handles all the generic cxl events, so that the AFU driver only needs to worry about it's own events.
fetch_event() return a struct cxl_event_afu_driver_reserved, allocated by the AFU driver, and filled in with the specific event information and size. Total event size (header + data) should not be greater than CXL_READ_MIN_SIZE (4K).
Th cxl driver prepends an appropriate cxl event header, copies the event to userspace, and finally calls event_delivered() to return the status of the operation to the AFU driver. The event is identified by the context and cxl_event_afu_driver_reserved pointers.
Since AFU drivers provide their own means for userspace to obtain the AFU file descriptor (i.e. cxlflash uses an ioctl on their scsi file descriptor to obtain the AFU file descriptor) and the generic cxl driver will never use this event, the ABI of the event is up to each individual AFU driver.

cxl: Add CXL_KERNEL_API config option
Add CXL_KERNEL_API config option so drivers which depend on this new functionality won't be enabled until this is visible.
This is useful for merging the cxlflash driver which comes in via the SCSI tree. The cxlflash driver can depend on CXL_KERNEL_API, hence it won't be enabled in the SCSI tree until this new config option is merged via the powerpc tree. Hence all trees will be bisectable at all times.

cxl: Add base builtin support
This adds the base cxl support that cannot be built as a module. Specifically it adds the cxl callbacks that are called from the core powerpc mm code which must always exist irrespective of if the cxl module is loaded or not. This is similar to how cell works with CONFIG_SPU_BASE.
This adds a cxl_slbia() call (similar to spu_flush_all_slbs()) which checks if the cxl module is loaded and in use, returning immediately if it is not. If it is in use it calls into the cxl SLB invalidation code.

misc: remove redundant 'default n' from Kconfig-s 'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...

cxl: Export library to support IBM XSL This patch exports a in-kernel 'library' API which can be called by other drivers to help interacting with an IBM XSL on a POWER9 system. The XSL (Translation Service Layer) is a stripped down version of the PSL (Power Service Layer) used in some cards such as the Mellanox CX5. Like the PSL, it implements the CAIA architecture, but has a number of differences, mostly in it's implementation dependent registers. The XSL also uses a special DMA cxl mode, which uses a slightly different init sequence for the CAPP and PHB.

cxl: Add cxl_check_and_switch_mode() API to switch bi-modal cards Add a new API, cxl_check_and_switch_mode() to allow for switching of bi-modal CAPI cards, such as the Mellanox CX-4 network card. When a driver requests to switch a card to CAPI mode, use PCI hotplug infrastructure to remove all PCI devices underneath the slot. We then write an updated mode control register to the CAPI VSEC, hot reset the card, and reprobe the card. As the card may present a different set of PCI devices after the mode switch, use the infrastructure provided by the pnv_php driver and the OPAL PCI slot management facilities to ensure that: * the old devices are removed from both the OPAL and Linux device trees * the new devices are probed by OPAL and added to the OPAL device tree * the new devices are added to the Linux device tree and probed through the regular PCI device probe path As such, introduce a new option, CONFIG_CXL_BIMODAL, with a dependency on the pnv_php driver. Refactor existing code that touches the mode control register in the regular single mode case into a new function, setup_cxl_protocol_area().

cxl: Add mechanism for delivering AFU driver specific events This adds an afu_driver_ops structure with fetch_event() and event_delivered() callbacks. An AFU driver such as cxlflash can fill this out and associate it with a context to enable passing custom AFU specific events to userspace. This also adds a new kernel API function cxl_context_pending_events(), that the AFU driver can use to notify the cxl driver that new specific events are ready to be delivered, and wake up anyone waiting on the context wait queue. The current count of AFU driver specific events is stored in the field afu_driver_events of the context structure. The cxl driver checks the afu_driver_events count during poll, select, read, etc. calls to check if an AFU driver specific event is pending, and calls fetch_event() to obtain and deliver that event. This way, the cxl driver takes care of all the usual locking semantics around these calls and handles all the generic cxl events, so that the AFU driver only needs to worry about it's own events. fetch_event() return a struct cxl_event_afu_driver_reserved, allocated by the AFU driver, and filled in with the specific event information and size. Total event size (header + data) should not be greater than CXL_READ_MIN_SIZE (4K). Th cxl driver prepends an appropriate cxl event header, copies the event to userspace, and finally calls event_delivered() to return the status of the operation to the AFU driver. The event is identified by the context and cxl_event_afu_driver_reserved pointers. Since AFU drivers provide their own means for userspace to obtain the AFU file descriptor (i.e. cxlflash uses an ioctl on their scsi file descriptor to obtain the AFU file descriptor) and the generic cxl driver will never use this event, the ABI of the event is up to each individual AFU driver.
