Commit ee3d9bd4de1ed93d2a7ee41c331ed30a1c7b8acd, while greatly simplifying the kernel SIGSEGV handler that runs in the process address space, introduced a bug which corrupts FP state in the process. Previously, the SIGSEGV handler called the sigreturn system call by hand - it couldn't return

[RFC v3 6/7] dmaengine: Driver for the Synopsys DesignWare DMA controller

This adds a driver for the Synopsys DesignWare DMA controller (aka DMACA on AVR32 systems.) This DMA controller can be found integrated on the AT32AP7000 chip and is primarily meant for peripheral DMA transfer, but can also be used for memory-to-memory transfers. This patch is based on a driver

This is a driver for the MMC controller on the AP7000 chips from Atmel. It should in theory work on AT91 systems too with some tweaking, but since the DMA interface is quite different, it's not entirely clear if it's worth it. This driver has been around for a while in BSPs and kernel sources

This moves the code checking if a DMA channel is in use from show_in_use() into an inline helper function, dma_is_in_use(). DMA controllers can use this in order to give clients exclusive access to channels (usually necessary when setting up slave DMA.) I have to admit that I don't really

[PATCH 2.6.24-mm1 8/8] (resend) IPC: consolidate all xxxctl_down() functions

2008-02-12 Thread pierre . peiffer
semctl_down(), msgctl_down() and shmctl_down() are used to handle the same set of commands for each kind of IPC. They all start to do the same job (they retrieve the ipc and do some permission checks) before handling the commands on their own. This patch proposes to consolidate this by moving

2008-02-12 Thread pierre . peiffer
From: Pierre Peiffer <[EMAIL PROTECTED]> All IPCs make use of an intermetiate *_setbuf structure to handle the IPC_SET command. This is not really needed and, moreover, it complicates a little bit the code. This patch get rid of the use of it and uses directly the semid64_ds/

2008-02-12 Thread pierre . peiffer
From: Pierre Peiffer <[EMAIL PROTECTED]> Currently, sys_msgctl is not easy to read. This patch tries to improve that by introducing the msgctl_down function to handle all commands requiring the rwmutex to be taken in write mode (ie IPC_SET and IPC_RMID for now). It is the equivalent function of
