* [PATCH] Use delayed disable mode of ioapic edge triggered interruptsEric W. Biederman2006-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Komuro reports that ISA interrupts do not work after a disable_irq(), causing some PCMCIA drivers to not work, with messages like eth0: Asix AX88190: io 0x300, irq 3, hw_addr xx:xx:xx:xx:xx:xx eth0: found link beat eth0: autonegotiation complete: 100baseT-FD selected eth0: interrupt(s) dropped! eth0: interrupt(s) dropped! eth0: interrupt(s) dropped! ... Linus Torvalds <torvalds@osdl.org> said: "Now, edge-triggered interrupts are a _lot_ harder to mask, because the Intel APIC is an unbelievable piece of sh*t, and has the edge-detect logic _before_ the mask logic, so if a edge happens _while_ the device is masked, you'll never ever see the edge ever again (unmasking will not cause a new edge, so you simply lost the interrupt). So when you "mask" an edge-triggered IRQ, you can't really mask it at all, because if you did that, you'd lose it forever if the IRQ comes in while you masked it. Instead, we're supposed to leave it active, and set a flag, and IF the IRQ comes in, we just remember it, and mask it at that point instead, and then on unmasking, we have to replay it by sending a self-IPI." This trivial patch solves the problem. Signed-off-by: Eric W.

| * [PATCH] x86-64: Fix vgetcpu when CONFIG_HOTPLUG_CPU is disabledAndi Kleen2006-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vgetcpu per CPU initialization previously relied on CPU hotplug events for all CPUs to initialize the per CPU state. That only worked only on kernels with CONFIG_HOTPLUG_CPU enabled. On the others some CPUs didn't get their state initialized properly and vgetcpu wouldn't work. Change the initialization sequence to instead run in a normal initcall (which runs after the normal CPU bootup) and initialize all running CPUs there. Later hotplug CPUs are still handled with an hotplug notifier. This actually simplifies the code somewhat. Signed-off-by: Andi Kleen <ak@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Timer overrides are normally disabled on Nvidia board because they are commonly wrong, except on new ones with HPET support. Unfortunately there are quite some Asus boards around that don't have HPET, but need a timer override. We don't know yet how to handle this transparently, but at least add a command line option to force the timer override and let them boot.

| * [PATCH] x86-64: setup saved_max_pfn correctly (kdump)Magnus Damm2006-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86_64: setup saved_max_pfn correctly 2.6.19-rc4 has broken CONFIG_CRASH_DUMP support on x86_64. It is impossible to read out the kernel contents from /proc/vmcore because saved_max_pfn is set to zero instead of the max_pfn value before the user map is setup. This happens because saved_max_pfn is initialized at parse_early_param() time, and at this time no active regions have been registered. save_max_pfn is setup from e820_end_of_ram(), more exact find_max_pfn_with_active_regions() which returns 0 because no regions exist.

| * [PATCH] x86-64: shorten the x86_64 boot setup GDT to what the comment saysSteven Rostedt2006-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stephen Tweedie, Herbert Xu, and myself have been struggling with a very nasty bug in Xen. But it also pointed out a small bug in the x86_64 kernel boot setup. The GDT limit being setup by the initial bzImage code when entering into protected mode is way too big. The comment by the code states that the size of the GDT is 2048, but the actual size being set up is much bigger (32768). This happens simply because of one extra '0'. Instead of setting up a 0x800 size, 0x8000 is set up. On bare metal this is fine because the CPU wont load any segments unless they are explicitly used. But unfortunately, this breaks Xen on vmx FV, since it (for now) blindly loads all the segments into the VMCS if they are less than the gdt limit. Since the real mode segments are around 0x3000, we are getting junk into the VMCS and that later causes an exception. Stephen Tweedie has written up a patch to fix the Xen side and will be submitting that to those folks. But that doesn't excuse the GDT limit being a magnitude too big.

* | [PATCH] hugetlb: prepare_hugepage_range check offset tooHugh Dickins2006-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (David:) If hugetlbfs_file_mmap() returns a failure to do_mmap_pgoff() - for example, because the given file offset is not hugepage aligned - then do_mmap_pgoff will go to the unmap_and_free_vma backout path. But at this stage the vma hasn't been marked as hugepage, and the backout path will call unmap_region() on it. That will eventually call down to the non-hugepage version of unmap_page_range(). On ppc64, at least, that will cause serious problems if there are any existing hugepage pagetable entries in the vicinity - for example if there are any other hugepage mappings under the same PUD. unmap_page_range() will trigger a bad_pud() on the hugepage pud entries. I suspect this will also cause bad problems on ia64, though I don't have a machine to test it on. (Hugh:) prepare_hugepage_range() should check file offset alignment when it checks virtual address and length, to stop MAP_FIXED with a bad huge offset from unmapping before it fails further down. PowerPC should apply the same prepare_hugepage_range alignment checks as ia64 and all the others do. Then none of the alignment checks in hugetlbfs_file_mmap are required (nor is the check for too small a mapping); but even so, move up setting of VM_HUGETLB and add a comment to warn of what David Gibson discovered - if hugetlbfs_file_mmap fails before setting it, do_mmap_pgoff's unmap_region when unwinding from error will go the non-huge way, which may cause bad behaviour on architectures (powerpc and ia64) which segregate their huge mappings into a separate region of the address space.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The enablement of 64k pages on pseries platforms exposed a bug in the RTAS mechanism for updating firmware. RTAS assumes 4k for flash block and list sizes, and use of any other sizes results in a failure, even though PAPR does not specify any such requirement. This patch changes the rtas_flash module to force the use of 4k memory block and list sizes when preparing and sending a firmware image to RTAS. The rtas_flash function now uses a slab cache of 4k blocks with 4k alignment, rather than get_zeroed_page(), to allocate the memory for the flash blocks and lists. The 4k alignment requirement is specified in PAPR. Signed-off-by: John Rose <johnrose@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

The result is a boot hang; which is really nasty. The patch below is a minimally safe patch to fix this regression for 2.6.19 by just not requesting actual microcode updates during early boot. (That is a good idea in general anyway) The "real" fix is a lot more complex given the entire cpu hotplug scenario (during cpu hotplug you normally need to load the microcode as well); but the interactions for that are just really messy at this point; this fix at least makes it work and avoids a full detangle of hotplug.

| * [ARM] 3918/1: ixp4xx irq-chip reworkKevin Hilman2006-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a rework of the ixp4xx irq_chip implementation. The use of two irq_chip structures and potentially switching between them is a violation of the intended use of the IRQ framework. The current implementation does not work with current in-kernel spinlock debugging or lockdep due to lock recursion problems caused by calling set_irq_chip/handler from within the chip's set_irq_type(). This patch goes back to using one irq_chip structure and handling the differences between edge/level, normal/GPIO interrupts inside the ack/mask/unmask routines themselves.

| * [ARM] 3912/1: Make PXA270 advertise HWCAP_IWMMXT capabilityPaul Gortmaker2006-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | ARM patch 3756/1 added HWCAP_IWMMXT. This patch adds support for broadcasting that info via /proc/cpuinfo and sets it for the CPU features of the PXA270. I've booted 19rc3 on a pxa270 and confirmed that the /proc/cpuinfo shows "iwmmxt" in the Features.
