2008-02-01ACPI suspend: Call _PTS before suspending devicesRafael J. Wysocki
The ACPI 1.0 specification wants us to put devices into low power states after executing the _PTS global control method, while ACPI 2.0 and later want us to do that in the reverse order. The current suspend code follows ACPI 2.0 in that respect which causes some ACPI 1.0x systems to hang during suspend (ref. http://bugzilla.kernel.org/show_bug.cgi?id=9528). Make the suspend code execute _PTS before putting devices into low power states (ie. in accordance with ACPI 1.0x) and provide a command line option to override the default if need be.

2008-01-30x86_32: trim memory by updating e820Yinghai Lu
when MTRRs are not covering the whole e820 table, we need to trim the RAM and need to update e820. reuse some code on 64-bit as well. here need to add early_get_cap and use it in early_cpu_detect, and move mtrr_bp_init early. The code successfully trimmed the memory map on Justin's system: from: [ 0.000000] BIOS-e820: 0000000100000000 - 000000022c000000 (usable) to: [ 0.000000] modified: 0000000100000000 - 0000000228000000 (usable) [ 0.000000] modified: 0000000228000000 - 000000022c000000 (reserved) According to Justin it makes quite a difference: | When I boot the box without any trimming it acts like a 286 or 386, | takes about 10 minutes to boot (using raptor disks).

2008-01-30x86, 32-bit: trim memory not covered by wb mtrrsJesse Barnes
On some machines, buggy BIOSes don't properly setup WB MTRRs to cover all available RAM, meaning the last few megs (or even gigs) of memory will be marked uncached. Since Linux tends to allocate from high memory addresses first, this causes the machine to be unusably slow as soon as the kernel starts really using memory (i.e. right around init time). This patch works around the problem by scanning the MTRRs at boot and figuring out whether the current end_pfn value (setup by early e820 code) goes beyond the highest WB MTRR range, and if so, trimming it to match. A fairly obnoxious KERN_WARNING is printed too, letting the user know that not all of their memory is available due to a likely BIOS bug. Something similar could be done on i386 if needed, but the boot ordering would be slightly different, since the MTRR code on i386 depends on the boot_cpu_data structure being setup. This patch fixes a bug in the last patch that caused the code to run on non-Intel machines (AMD machines apparently don't need it and it's untested on other non-Intel machines, so best keep it off).

2008-01-30x86: add the "print code before the trapping instruction" feature to 64 bitArjan van de Ven
The 32 bit x86 tree has a very useful feature that prints the Code: line for the code even before the trapping instrution (and the start of the trapping instruction is then denoted with a <>). Unfortunately, the 64 bit x86 tree does not yet have this feature, making diagnosing backtraces harder than needed. This patch adds this feature in the same was as the 32 bit tree has (including the same kernel boot parameter), and including a bugfix to make the code use probe_kernel_address() rarther than a buggy (deadlocking) __get_user.

2008-01-30x86 vDSO: consolidate vdso32Roland McGrath
This makes x86_64's ia32 emulation support share the sources used in the 32-bit kernel for the 32-bit vDSO and much of its setup code. The 32-bit vDSO mapping now behaves the same on x86_64 as on native 32-bit. The abi.syscall32 sysctl on x86_64 now takes the same values that vm.vdso_enabled takes on the 32-bit kernel. That is, 1 means a randomized vDSO location, 2 means the fixed old address. The CONFIG_COMPAT_VDSO option is now available to make this the default setting, the same meaning it has for the 32-bit kernel. (This does not affect the 64-bit vDSO.) The argument vdso32=[012] can be used on both 32-bit and 64-bit kernels to set this paramter at boot time. The vdso=[012] argument still does this same thing on the 32-bit kernel.

2008-01-30x86: provide a DMI based port 0x80 I/O delay override.Rene Herman
x86: provide a DMI based port 0x80 I/O delay override. Certain (HP) laptops experience trouble from our port 0x80 I/O delay writes. This patch provides for a DMI based switch to the "alternate diagnostic port" 0xed (as used by some BIOSes as well) for these. David P. Reed confirmed that port 0xed works for him and provides a proper delay. The symptoms of _not_ working are a hanging machine, with "hwclock" use being a direct trigger. Earlier versions of this attempted to simply use udelay(2), with the 2 being a value tested to be a nicely conservative upper-bound with help from many on the linux-kernel mailinglist but that approach has two problems. First, pre-loops_per_jiffy calibration (which is post PIT init while some implementations of the PIT are actually one of the historically problematic devices that need the delay) udelay() isn't particularly well-defined. We could initialise loops_per_jiffy conservatively (and based on CPU family so as to not unduly delay old machines) which would sort of work, but... Second, delaying isn't the only effect that a write to port 0x80 has. It's also a PCI posting barrier which some devices may be explicitly or implicitly relying on. Alan Cox did a survey and found evidence that additionally some drivers may be racy on SMP without the bus locking outb. Switching to an inb() makes the timing too unpredictable and as such, this DMI based switch should be the safest approach for now. Any more invasive changes should get more rigid testing first. It's moreover only very few machines with the problem and a DMI based hack seems to fit that situation. This also introduces a command-line parameter "io_delay" to override the DMI based choice again: io_delay=<standard|alternate> where "standard" means using the standard port 0x80 and "alternate" port 0xed. This retains the udelay method as a config (CONFIG_UDELAY_IO_DELAY) and command-line ("io_delay=udelay") choice for testing purposes as well. This does not change the io_delay() in the boot code which is using the same port 0x80 I/O delay but those do not appear to be a problem as David P. Reed reported the problem was already gone after using the udelay version. He moreover reported that booting with "acpi=off" also fixed things and seeing as how ACPI isn't touched until after this DMI based I/O port switch I believe it's safe to leave the ones in the boot code be. The DMI strings from David's HP Pavilion dv9000z are in there already and we need to get/verify the DMI info from other machines with the problem, notably the HP Pavilion dv6000z. This patch is partly based on earlier patches from Pavel Machek and David P. Reed.

* ssh://master.kernel.org/pub/scm/linux/kernel/git/tglx/linux-2.6-x86: (33 commits) x86: convert cpuinfo_x86 array to a per_cpu array x86: introduce frame_pointer() and stack_pointer() x86 & generic: change to __builtin_prefetch() i386: do not BUG_ON() when MSR is unknown x86: acpi use cpu_physical_id x86: convert cpu_llc_id to be a per cpu variable x86: convert cpu_to_apicid to be a per cpu variable i386: introduce "used_vectors" bitmap which can be used to reserve vectors. x86: use raw locks during oopses x86: honor _PAGE_PSE bit on page walks i386: do cpuid_device_create() in CPU_UP_PREPARE instead of CPU_ONLINE. x86: implement missing x86_64 function smp_call_function_mask() x86: use descriptor's functions instead of inline assembly i386: consolidate show_regs and show_registers for i386 i386: make callgraph use dump_trace() on i386/x86_64 x86: enable iommu_merge by default i386: i386 add AMD64 Barcelona PMU MSR definitions to msr.h x86: Unify i386 and x86-64 early quirks x86: enable HPET on ICH3 and ICH4 x86: force enable HPET on VT8235/8237 chipsets ... Manually fix trivial conflict with task pid container helper changes in arch/x86/kernel/process_32.c
