[PATCH 2/5] rbtree: include rcu.h because we use it

Since commit c1adf20052d8 ("Introduce rb_replace_node_rcu()") rbtree_augmented.h uses RCU related data structures but does not include them. It works as long as gets somehow included before that and fails otherwise. Cc: David Howells Cc: "Peter Zijlstra (Intel)"

[PATCH 4/5] iommu/iova: don't disable preempt around this_cpu_ptr()

Commit 583248e6620a ("iommu/iova: Disable preemption around use of this_cpu_ptr()") disables preemption while accessing a per-CPU variable. This does keep lockdep quiet. However I don't see the point why it is bad if we get migrated after its access to another CPU. __iova_rcache_insert() and

[PATCH 0/2] Broadcom BCM54612E support

This series is based on tip of torvalds/master. The first patch adds register definitions from Broadcom docs. The second patch adds the BCM54612E PHY ID, flags, and device-specific RGMII internal delay initialization. I tested on a custom board with an Aspeed AST2500 SOC with its second MAC

[PATCH V4 00/10] Add UEFI 2.6 and ACPI 6.1 updates for RAS on ARM64

When a memory error, CPU error, PCIe error, or other type of hardware error that's covered by RAS occurs, firmware should populate the shared GHES memory location with the proper GHES structures to notify the OS of the error. For example, platforms that implement firmware first handling may

A RAS (Reliability, Availability, Serviceability) controller may be a separate processor running in parallel with OS execution, and may generate error records for consumption by the OS. If the RAS controller produces multiple error records, then they may be overwritten before the OS has consumed

[PATCH V4 02/10] ras: acpi/apei: cper: generic error data entry v3 per ACPI 6.1

Currently when a RAS error is reported it is not timestamped. The ACPI 6.1 spec adds the timestamp field to the generic error data entry v3 structure. The timestamp of when the firmware generated the error is now being reported. Signed-off-by: Jonathan (Zhixiong) Zhang

Pure polling mode for netdevices

Is there a way to get NAPI to poll all the time? Or just any way to get netdevices to use only polling and no interrupts? We have some rt targets where the jitter can be improved by disabling interrupts and using just polling. In these cases we're okay with the performance downsides that come
