[PATCHv2 03/11] staging: usbip: Add kernel support for client ACLs

This patch adds the possibility to stored ACLs for allowed clients for each stub device in sysfs. It adds a new sysfs entry called "usbip_acl" for each stub device, containing a list of CIDR masks of allowed clients. This file will be used by usbip and usbipd to store the ACL. Signed-off-by: Kurt

[PATCH v3 3/5] x86, acpi, crash, kdump: Do reserve_crashkernel() after SRAT is parsed.

Memory reserved for crashkernel could be large. So we should not allocate this memory bottom up from the end of kernel image. When SRAT is parsed, we will be able to know whihc memory is hotpluggable, and we can avoid allocating this memory for the kernel. So reorder reserve_crashkernel() after SR

[PATCH v3 2/5] memblock: Improve memblock to support allocation from lower address.

This patch modifies the memblock_find_in_range_node() to support two different allocation directions. After this patch, memblock will check memblock.current_direction, and decide in which direction to allocate memory. Now it supports two allocation directions: bottom up and top down. When directio

[PATCH v3 1/5] memblock: Introduce allocation direction to memblock.

The Linux kernel cannot migrate pages used by the kernel. As a result, kernel pages cannot be hot-removed. So we cannot allocate hotpluggable memory for the kernel. ACPI SRAT (System Resource Affinity Table) contains the memory hotplug info. But before SRAT is parsed, memblock has already started

[PATCH v3 5/5] mem-hotplug: Introduce movablenode boot option to control memblock allocation direction.

The Hot-Pluggable fired in SRAT specifies which memory is hotpluggable. As we mentioned before, if hotpluggable memory is used by the kernel, it cannot be hot-removed. So memory hotplug users may want to set all hotpluggable memory in ZONE_MOVABLE so that the kernel won't use it. Memory hotplug us

[PATCH v3 4/5] x86, mem-hotplug: Support initialize page tables from low to high.

init_mem_mapping() is called before SRAT is parsed. And memblock will allocate memory for page tables. To prevent page tables being allocated within hotpluggable memory, we will allocate page tables from the end of kernel image to the higher memory. Signed-off-by: Tang Chen Reviewed-by: Zhang Ya
