Merge tag 'fixes-2024-04-08' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock
Pull memblock fixes from Mike Rapoport:
"Fix build errors in memblock tests:
- add stubs to functions that calls to them were recently added to
memblock but they were missing in tests
- update gfp_types.h to include bits.h so that BIT() definitions
won't depend on other includes"
* tag 'fixes-2024-04-08' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock:
memblock tests: fix undefined reference to `BIT'
memblock tests: fix undefined reference to `panic'
memblock tests: fix undefined reference to `early_pfn_to_nid'

+==========================
+Devlink E-Switch Attribute
+==========================
+
+Devlink E-Switch supports two modes of operation: legacy and switchdev.
+Legacy mode operates based on traditional MAC/VLAN steering rules. Switching
+decisions are made based on MAC addresses, VLANs, etc. There is limited ability
+to offload switching rules to hardware.
+
+On the other hand, switchdev mode allows for more advanced offloading
+capabilities of the E-Switch to hardware. In switchdev mode, more switching
+rules and logic can be offloaded to the hardware switch ASIC. It enables
+representor netdevices that represent the slow path of virtual functions (VFs)
+or scalable-functions (SFs) of the device. See more information about
+:ref:`Documentation/networking/switchdev.rst <switchdev>` and
+:ref:`Documentation/networking/representors.rst <representors>`.
+
+In addition, the devlink E-Switch also comes with other attributes listed
+in the following section.
+
+Attributes Description
+======================
+
+The following is a list of E-Switch attributes.
+
+.. list-table:: E-Switch attributes
+ :widths: 8 5 45
+
+ * - Name
+ - Type
+ - Description
+ * - ``mode``
+ - enum
+ - The mode of the device. The mode can be one of the following:
+
+ * ``legacy`` operates based on traditional MAC/VLAN steering
+ rules.
+ * ``switchdev`` allows for more advanced offloading capabilities of
+ the E-Switch to hardware.
+ * - ``inline-mode``
+ - enum
+ - Some HWs need the VF driver to put part of the packet
+ headers on the TX descriptor so the e-switch can do proper
+ matching and steering. Support for both switchdev mode and legacy mode.
+
+ * ``none`` none.
+ * ``link`` L2 mode.
+ * ``network`` L3 mode.
+ * ``transport`` L4 mode.
+ * - ``encap-mode``
+ - enum
+ - The encapsulation mode of the device. Support for both switchdev mode
+ and legacy mode. The mode can be one of the following:
+
+ * ``none`` Disable encapsulation support.
+ * ``basic`` Enable encapsulation support.
+
+Example Usage

+Firmware Management
+===================

+The SEV guest key management is handled by a separate processor called the AMD

+The AMD-SP firmware can be initialized either by using its own non-volatile

-/*
- * One based indexing version:
+ * array.
*
- * With one based indexing each level of the tree starts at a power of two -
- * good for cacheline alignment:
+ * Consider using an eytzinger tree any time you would otherwise be doing binary
+ * search over an array. Binary search is a worst case scenario for branch
+ * prediction and prefetching, but in an eytzinger tree every node's children
+ * are adjacent in memory, thus we can prefetch children before knowing the
+ * result of the comparison, assuming multiple nodes fit on a cacheline.
+ *
+ * Two variants are provided, for one based indexing and zero based indexing.
+ *
+ * Zero based indexing is more convenient, but one based indexing has better
+ * alignment and thus better performance because each new level of the tree
+ * starts at a power of two, and thus if element 0 was cacheline aligned, each
+ * new level will be as well.
