Asit Mallick pointed out that the ia64 idle loop needs a "hint @pause" instruction in the cases where we don't actually halt the cpu. Acked-by:

In the absence of an HCDP, we used to assume there were legacy COM ports at 0x3f8 and 0x2f8, but I recently removed that assumption. "console=ttyS0" still works (assuming you have CONFIG_SERIAL_8250_ACPI turned on so you can find the ttyS0 device), but the console doesn't start working until the serial driver initializes. If you need an early console and you know where it lives, something like "console=uart,io,0x3f8" will start working very early. Signed-off-by:

This patch fixes an an "off-by-one" error found in the CCISS_GETLUNIFO ioctl in the cciss driver. It is cycling through the part table of the gendisk structure which is a zero-based array, not a one-based array. This often causes an oops when referencing the out-of-bounds element.

The field info->modelist is initialized during register_framebuffer. This field is also referred to in fb_set_var(). Thus a call to fb_set_var() before register_framebuffer() will cause a crash. A few drivers do this, notably controlfb. (This might fix reports of controlfb crashing in powermacs). Signed-off-by:

Patch from Petr Vandrovec <vandrove@vc.cvut.cz> Recently I've observed problems with IDE disks while running UP kernel on x86-64 - it complained a lot about lost irq from hda/hdc. I tracked problem down to the problem that at enable_irq() code calls hw_resend_irq(), but on x86-64 hw_resend_irq() does something useful only when CONFIG_SMP is defined, on UP systems it does nothing. Due to this IRQ is lost - and when IDE retries command, it can again happen that IRQ is delivered before IDE code does enable_irq(), and again and again, unless due to drive being lazy finally once kernel does enable_irq() before drive prepares its answer, and things move forward ... to next lost IRQ.

The accounting of shmctl() SHM_LOCK memory locks against the user structure is broken. The check of the size of the to-be-locked region is based on the size of the segment as specified when it was created by shmget() (this size is *not* rounded up to a page boundary). Fix it by rounding the size properlt. Also, tune up the spinlock coverage in there a little. Signed-off-by:

Revert my version of this fix and apply Scott's version, which was acked by the e100 maintainers. Also, initialise the spinlocks before calling e100_hw_reset(), so things don't instantly deadlock on SMP. Signed-off-by:

Patch from Holger Hans Peter Freyther Line numbers could depend on 2279/1 Change the maintainer of the SIMpad board to me. This change was discussed on the simpad linux mailinglist and was supported by the former maintainer of SIMpad. I'll subscribe and introduce myself shortly on the arm linux mailinglist and ask for SIMpad not to be removed. Signed-off-by: Holger Hans Peter Freyther Signed-off-by: Russell King

Patch from Holger Hans Peter Freyther The SIMpad uses the MediaQ 200 framebuffer device. There is no driver in the vanilla kernel for that device. But adding the device to the platform bus makes it possible to just drop the mq200 driver into the kernel and the display will work. Please consider applying the patch.

* switched to ioremap() + normal operations * split msnd_fifo_write() (and msnd_fifo_read()) into iomem and normal versions (original was even worse - it used to do __user and __iomem versions in the same code and in atomic context; when that bogosity got fixed, the difference between these cases (now normal memory and iomem) had been lost).
