2007-08-12genirq: mark io_apic level interrupts to avoid resendThomas Gleixner
Level type interrupts do not need to be resent. It was also found that some chipsets get confused in case of the resend. Mark the ioapic level type interrupts as such to avoid the resend functionality in the generic irq code.

2007-08-12Do not replace whole memcpy in apply alternativesPetr Vandrovec
apply_alternatives uses memcpy() to apply alternatives. Which has the unfortunate effect that while applying memcpy alternative to memcpy itself it tries to overwrite itself with nops - which causes #UD fault as it overwrites half of an instruction in copy loop, and from this point on only possible outcome is triplefault and reboot. So let's overwrite only first two instructions of memcpy - as long as the main memcpy loop is not in first two bytes it will work fine.

2007-08-11i386: Fix double fault handlerChuck Ebbert
The new percpu code has apparently broken the doublefault handler when CONFIG_DEBUG_SPINLOCK is set. Doublefault is handled by a hardware task, making the check SPIN_BUG_ON(lock->owner == current, lock, "recursion"); fault because it uses the FS register to access the percpu data for current, and that register is zero in the new TSS. (The trace I saw was on 2.6.20 where it was GS, but it looks like this will still happen with FS on 2.6.22.) Initializing FS in the doublefault_tss should fix it.

2007-08-11i386: Use global flag to disable broken local apic timer on AMD CPUs.Andi Kleen
The Averatec 2370 and some other Turion laptop BIOS seems to program the ENABLE_C1E MSR inconsistently between cores. This confuses the lapic use heuristics because when C1E is enabled anywhere it seems to affect the complete chip. Use a global flag instead of a per cpu flag to handle this. If any CPU has C1E enabled disabled lapic use. Thanks to Cal Peake for debugging.

VT is very picky about when it can enter execution. Get all segments setup and get LDT and TR into valid state to allow VT execution under VMware and KVM (untested). This makes the boot decompression run under VT, which makes it several orders of magnitude faster on 64-bit Intel hardware.

2007-08-11i386: Make patching more robust, fix paravirt issueAndi Kleen
Commit 19d36ccdc34f5ed444f8a6af0cbfdb6790eb1177 "x86: Fix alternatives and kprobes to remap write-protected kernel text" uses code which is being patched for patching. In particular, paravirt_ops does patching in two stages: first it calls paravirt_ops.patch, then it fills any remaining instructions with nop_out(). nop_out calls text_poke() which calls lookup_address() which calls pgd_val() (aka paravirt_ops.pgd_val): that call site is one of the places we patch. If we always do patching as one single call to text_poke(), we only need make sure we're not patching the memcpy in text_poke itself. This means the prototype to paravirt_ops.patch needs to change, to marshal the new code into a buffer rather than patching in place as it does now. It also means all patching goes through text_poke(), which is known to be safe (apply_alternatives is also changed to make a single patch). AK: fix compilation on x86-64 (bad rusty!)

2007-08-11finish i386 and x86-64 sysdata conversionMuli Ben-Yehuda
This patch finishes the i386 and x86-64 ->sysdata conversion and hopefully also fixes Riku's and Andy's observed bugs. It is based on Yinghai Lu's and Andy Whitcroft's patches (thanks!) with some changes: - introduce pci_scan_bus_with_sysdata() and use it instead of pci_scan_bus() where appropriate. pci_scan_bus_with_sysdata() will allocate the sysdata structure and then call pci_scan_bus(). - always allocate pci_sysdata dynamically. The whole point of this sysdata work is to make it easy to do root-bus specific things (e.g., support PCI domains and IOMMU's). I dislike using a default struct pci_sysdata in some places and a dynamically allocated pci_sysdata elsewhere - the potential for someone indavertantly changing the default structure is too high. - this patch only makes the minimal changes necessary, i.e., the NUMA node is always initialized to -1. Patches to do the right thing with regards to the NUMA node can build on top of this (either add a 'node' parameter to pci_scan_bus_with_sysdata() or just update the node when it becomes known). The patch was compile tested with various configurations (e.g., NUMAQ, VISWS) and run-time tested on i386 and x86-64. Unfortunately none of my machines exhibited the bugs so caveat emptor. Andy, could you please see if this fixes the NUMA issues you've seen? Riku, does this fix "pci=noacpi" on your laptop?

2007-08-11x86_64: fix HPET init raceRobin Holt
I have had four seperate system lockups attributable to this exact problem in two days of testing. Instead of trying to handle all the weird end cases and wrap, how about changing it to look for exactly what we appear to want. The following patch removes a couple races in setup_APIC_timer. One occurs when the HPET advances the COUNTER past the T0_CMP value between the time the T0_CMP was originally read and when COUNTER is read. This results in a delay waiting for the counter to wrap. The other results from the counter wrapping. This change takes a snapshot of T0_CMP at the beginning of the loop and simply loops until T0_CMP has changed (a tick has happened). <later> I have one small concern about the patch. I am not sure it meets the intent as well as it should. I think we are trying to match APIC timer interrupts up with the hpet counter increment. The event which appears to be disturbing this loop in our test environment is the NMI watchdog. What we believe has been happening with the existing code is the setup_APIC_timer loop has read the CMP value, and the NMI watchdog code fires for the first time. This results in a series of icache miss slowdowns and by the time we get back to things it has wrapped. I think this code is trying to get the CMP as close to the counter value as possible. If that is the intent, maybe we should really be testing against a "window" around the CMP. Something like COUNTER = CMP+/2. It appears COUNTER should get advanced every 89nSec (IIRC). The above seems like an unreasonably small window, but may be necessary. Without documentation, I am not sure of the original intent with this code. In summary, this code fixes my boot hangs, but since I am not certain of the intent of the existing code, I am not certain this has not introduced new bugs or unexpected behaviors.

My "slices" address space management code that was added in the 2.6.22 implementation of get_unmapped_area() doesn't properly check that the size is a multiple of the requested page size. This allows userland to create VMAs that aren't a multiple of the huge page size with hugetlbfs (since hugetlbfs entirely relies on get_unmapped_area() to do that checking) which leads to a kernel BUG() when such areas are torn down.

First, the code that generates the pci devices from the OF device-tree doesn't initialize the mask properly, then our implementation of set_dma_mask() was trying to validate the -previous- mask value, not the one passed in as an argument.

2007-08-03[POWERPC] Fixes for the SLB shadow buffer codeMichael Neuling
On a machine with hardware 64kB pages and a kernel configured for a 64kB base page size, we need to change the vmalloc segment from 64kB pages to 4kB pages if some driver creates a non-cacheable mapping in the vmalloc area. However, we never updated with SLB shadow buffer. This fixes it. Thanks to paulus for finding this. Also added some write barriers to ensure the shadow buffer contents are always consistent.

2007-08-03[POWERPC] Fix parse_drconf_memory() for 64-bit start addressesMichael Ellerman
Some new machines use the "ibm,dynamic-reconfiguration-memory" property to provide memory layout information, rather than via memory nodes. There is a bug in the code to parse this property for start addresses over 4GB; we store the start address in an unsigned int, which means we throw away the high bits and add apparently duplicate regions. This results in a BUG() in free_bootmem_core(). This fixes it by using an unsigned long instead.
