2010-02-25mtd: Raise limit on block device minor numbersBen Hutchings1-2/+5
add_mtd_blktrans_dev() imposes a maximum of 257 devices per block translator. This was presumably meant to prevent overflow back in the days of 8-bit minor numbers. Instead, check against MINORMASK and the limits of the partition naming scheme.

2010-02-25mtd: mtdblock: Dynamically allocate cache info structuresBen Hutchings1-43/+31
Since we allocate struct mtd_blktrans_dev for each block device, we can add our own structure members to the end. Therefore embed struct mtd_blktrans_dev in struct mtdblk_dev and remove the static array of struct mtdblk_dev. Also remove the redundant pointer to struct mtd_info. This is preparation for removing the static limit on the number of MTD devices.

2010-02-25mtd: mxc-nand: no need to check for validity of platform driver dataUwe Kleine-König1-10/+7
The probe function calls platform_set_drvdata with a valid pointer when the probe is successful. As mxcnd_suspend and mxcnd_resume are only called on bound devices, platform_get_drvdata always returns non-NULL. This fix isn't critical as the pointer is always valid so it doesn't matter if the compiler generated code for it or not.

crash_kexec gets called before kmsg_dump(KMSG_DUMP_OOPS) if panic_on_oops is set, so the kernel log buffer is not stored for this case. This patch adds a KMSG_DUMP_KEXEC dump type which gets called when crash_kexec() is invoked. To avoid getting double dumps, the old KMSG_DUMP_PANIC is moved below crash_kexec(). The mtdoops driver is modified to handle KMSG_DUMP_KEXEC in the same way as a panic.

2009-12-16gru: send cross partition interrupts using the gruJack Steiner2-15/+36
GRU Message queue instructions are used to deliver messages to other SSIs within the numalink domain. In most cases, a single GRU mesq instruction will deliver both the message AND an interrupt to notify the other SSI that a messsage is present. In some cases, however, the interrupt must be sent explicitly. To improve resilency, the GRU driver should send these explicit interrupts using the GRU to write the remote chipset register. Current code sends the interrupt using a cpu instruction to write the chipset register.
