This patch is required for S3 suspend-resume on noexec capable systems. On these systems, we need to save and restore MSR_EFER during S3 suspend-resume. Signed-off-by:

apm.c needs save_processor_state and friends. Add a comment to keep people from removing it. Describe a way to make swsusp work on non-PSE machines. Document purpose of acpi_restore_state. Signed-off-by:

Currently, process start times change after swsusp (because they are derived from jiffies and current time, oops). This should fix it. Signed-off-by:

Fix interaction between nosmp and pcibios_fixup_irqs(). When we boot with nosmp we dont have all the mptable info, so IO_APIC_get_PCI_irq_vector() doesnt work and devices just end up getting a wrong interrupt. From: Oleg Nesterov <oleg@tv-sign.ru> Acked-by:

As part of the workaround for the "Interrupt message re-ordering across hub interface" errata (page #16 in http://developer.intel.com/design/chipsets/specupdt/30288402.pdf), BIOS may enable hardware IRQ balancing for E7520/E7320/E7525(revision ID 0x9 and below) based platforms. Add pci quirks to disable SW irqbalance/affinity on those platforms. Move balanced_irq_init() to late_initcall so that kirqd will be started after pci quirks. Signed-off-by:

- valid_stack_ptr() erroneously assumes that stack always lives in task_struct->thread_info. - the main loop in show_trace() does not recalc ebp after stack switching. With CONFIG_FRAME_POINTER every call to print_context_stack() will produce the same output. With this patch, show_trace() does not use task argument in the main loop. Instead, it converts stack to thread_info* context, and passes it to print_context_stack() and (implicitly) to valid_stack_ptr(). valid_stack_ptr() now does bounds checking against proper context.

Some cache descriptors are missing from x86_64 table. So instead of copying from i386 code, here is a patch to share the table between i386 and x86_64. Signed-off-by:

The following fixes EMBEDDED_RAMDISK to work with O=. The problem was that we couldn't find the linker script, since we needed to specify the patch to the source tree for it. I've tested this with the ramdisk set to both 'ramdisk.gz' and '../ramdisk.gz'. Signed-off-by:

Previously we could do subtype parsing and cache configuration in the same location.. but with the introduction of things like the SH7705 where we use SH-3 style probing with SH-4 style caches, this is no longer the case. As such, we move the probe code to a saner place. Signed-off-by:

The early printk() code was using a fixed PCLK value that was only sane in the SH7750 case. This updates the SCBRR value calculation to use CONFIG_SH_PCLK_FREQ instead and thus works on other subtypes as well (tested on SH4-202). Signed-off-by:

This updates some of the sh DMA drivers and core API. Previously modules had to register for the channels they were interested in, but now it's dealt with transparently by the API with only the number of physical channels needing to be specified by each module. Signed-off-by:

This patch fixes a problem where my new powerbook would sometimes hang or crash when changing CPU speed. We had schedule_timeout(HZ/1000) in there, intended to provide a delay of one millisecond. However, even with HZ=1000, it was (I believe) only waiting for the next jiffy before proceeding, which could be less than a millisecond. Changing the code to use msleep, and specifying a time of 1 jiffy + 1ms has fixed the problem. (When I looked at the msleep code, it appeared to me that msleep(1) with HZ=1000 would sleep for between 0 and 1ms.) Ben also asked me to remove the code that changes the AACK delay enable, after looking in the Darwin sources and seeing that Darwin does not change this in its corresponding code. Signed-off-by:
