Split ACPI_DEBUG into function trace enabled and not enabled. Function trace is most of the ACPI_DEBUG costs, but is not much of use for kernel ACPI debugging. Size of kernel image increased on test compile: + 48k (Full ACPI_DEBUG) + 35k (ACPI_DEBUG with function trace compiled out) Performance without function trace is also much better. Also remove ACPI_LV_DEBUG_OBJECT from default debug level as a lot vendors let Store (value, debug) in their code and this might confuse users when it pops up in syslog. Signed-off-by:

Sorry, my fault. It looked to me like sparc64 exports sys_ioctl on it's own, but it only exports compat_sys_ioctl on it's own. Signed-off-by:

__ndelay and __udelay have not been delayung >= specified time. The problem with __ndelay has been tacked down to the rounding of the multiplier constant. By changing this, delays > app 18us are correctly calculated. The problem with __udelay has also been tracked down to rounding issues. Changing the multiplier constant (to match that used in sparc64) corrects for large delays and adding in a rounding constant corrects for trunctaion errors in the claculations. Many short delays will return without looping. This is not an error as there is the fixed delay of doing all the maths to calculate the loop count. Signed-off-by:

This patch introduces struct pci_sysdata to x86 and x86-64, and converts the existing two users (NUMA, Calgary) to use it. This lays the groundwork for having other users of sysdata, such as the PCI domains work. The Calgary bits are tested, the NUMA bits just look ok. Signed-off-by:

Dead or misnamed CONFIG_BALANCED_IRQ_DEBUG found by Robert P. J. Day. It's not a Kconfig variable. Since this debug code is ancient, I suggest to get rid of this misleading CONFIG_ macro by deleting all of this debug code. Signed-off-by:

Insert HPET resources after pci probing has been completed in order to avoid resource conflicts with PCI resource reservation. With this change the HPET firmware resources will be identified, but it should also not cause issues when the HPET address falls on a BAR in a PCI device, and the PCI enumeration cannot reserve the resources.

get_vm_area always returns an area with an adjacent guard page. That guard page is included in vm_struct.size. iounmap uses vm_struct.size to determine how much address space needs to have change_page_attr applied to it, which will BUG if applied to the guard page. This patch adds a helper function - get_vm_area_size() in linux/vmalloc.h - to return the actual size of a vm area, and uses it to make iounmap do the right thing. There are probably other places which should be using get_vm_area_size(). Thanks to Dave Young <hidave.darkstar@gmail.com> for debugging the problem. [ Andi, it wasn't clear to me whether x86_64 needs the same fix. ] Signed-off-by:

e820_hole_size() now uses the newly extracted helper function, e820_find_active_region(), to determine the size of usable RAM in a range of PFN's. This was previously broken because of two reasons: - The start and end PFN's of each e820 entry were not properly rounded prior to excluding those entries in the range, and - Entries smaller than a page were not properly excluded from being accumulated. This resulted in emulated nodes being incorrectly mapped to ranges that were completely reserved and not candidates for being registered as active ranges. Signed-off-by:

For K8 system: 4G RAM with memory hole remapping enabled, or more than 4G RAM installed. when using kexec to load second kernel. In the second kernel, when mem is allocated for GART, it will do the memset for clear, it will cause restart, because some device still used that for dma. solution will be: in second kernel: disable that at first before we try to allocate mem for it. or in the first kernel: do disable that before shutdown. Andi/Eric/Alan prefer to second one for clean shutdown in first kernel. Andi also point out need to consider to AGP enable but mem less 4G case too. Signed-off-by:
