From: Sonic Zhang <sonic.zhang@analog.com> Current SPI driver enables SPI controller and set the SPI baud register for each SPI transfer. But, they should never be changed within a SPI message session, in which seveal SPI transfers are pumped. This patch move move SPI setting to the begining of a message session. And never disables SPI controller until an error occurs. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com> --- driver...

This patch set is to fix panic due to access NULL pointer of SLUB. When new memory is hot-added on the new node (or memory less node), kmem_cache_node for the new node is not prepared, and panic occurs by it. So, kmem_cache_node should be created for the node before new memory is available on the node. Incidentally, it is freed on memory offline if it becomes not necessary. This is the first user of the callback of memory notifier, and requires its rearrange patch set. This patch set is for 2....

Hi guys, it has been 12 years since I was last actively working on linux 68k. Anyway, this time I have a problem report on i386: Background: I upgraded one machine from 2.6.21.5 to 2.6.23 and experienced boot failure due to the IDE disks being inaccessible. I worked out that the problem was introduced with 2.6.22-rc1. The machine has an Asus CUBX motherboard. The PIIX3 is switched off in the BIOS. All disks are hanging off the onboard CMD648 IDE controller which is connected to IRQ 15. E...

The current series applies to 23-rt1-pre1. This is a snapshot of the current work-in-progress for the rt-overload enhancements. The primary motivation for the series to to improve the algorithm for distributing RT tasks to keep the highest tasks active. The current system tends to blast IPIs "shotgun" style, and we aim to reduce that overhead where possible. We mitigate this behavior by trying to place tasks on the ideal runqueue before an overload even occurs. Note that this series is *not* c...

This code tracks the priority of each CPU so that global migration decisions are easy to calculate. Each CPU can be in a state as follows: (INVALID), IDLE, NORMAL, RT1, ... RT99 going from the lowest priority to the highest. CPUs in the INVALID state are not eligible for routing. The system maintains this state with a 2 dimensional bitmap (the first for priority class, the second for cpus in that class). Therefore a typical application without affinity restriction...
