* Revert "[PATCH] i386: export: memory more than 4G through /proc/iomem"Linus Torvalds2006-05-13
| | | | | | | | | | | | | | | | | | | This reverts commit 10dbe196a8da6b3196881269c6639c0ec11c36cb. The resource struct is still 32-bit, so trying to save a 64-bit memory size there obviously won't work. When we merge the 64-bit resource series, we can re-enable this.

* | [PATCH] x86_64: Avoid EBDA area in early boot allocatorAndi Kleen2006-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on analysis&patch from Robert Hentosch Observed on a Dell PE6850 with 16GB The problem occurs very early on, when the kernel allocates space for the temporary memory map called bootmap. The bootmap overlaps the EBDA region. EBDA region is not historically reserved in the e820 mapping. When the bootmap is freed it marks the EBDA region as usable. If you notice in setup.c there is already code to work around the EBDA in reserve_ebda_region(), this check however occurs after the bootmap is allocated and doesn't prevent the bootmap from using this range.

* | [PATCH] x86_64: add nmi_exit to die_nmiCorey Minyard2006-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Playing with NMI watchdog on x86_64, I discovered that it didn't do what I expected. It always panic-ed, even when it didn't happen from interrupt context. This patch solves that problem for me. Also, in this case, do_exit() will be called with interrupts disabled, I believe. Would it be wise to also call local_irq_enable() after nmi_exit()? [Yes I added it -AK] Currently, on x86_64, any NMI watchdog timeout will cause a panic because the irq count will always be set to be in an interrupt when do_exit() is called from die_nmi(). If we add nmi_exit() to the die_nmi() call (since the nmi will never exit "normally") it seems to solve this problem. The following small program can be used to trigger the NMI watchdog to reproduce this: main () { iopl(3); for (;;) asm("cli"); } Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | [PATCH] x86_64: fix die_lock nestingCorey Minyard2006-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | I noticed this when poking around in this area. The oops_begin() function in x86_64 would only conditionally claim the die_lock if the call is nested, but oops_end() would always release the spinlock. This patch adds a nest count for the die lock so that the release of the lock is only done on the final oops_end().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch addresses a problem with ACPI SCI interrupt entry, which gets re-used, and the IRQ is assigned to another unrelated device. The patch corrects the code such that SCI IRQ is skipped and duplicate entry is avoided. Second issue came up with VIA chipset, the problem was caused by original patch assigning IRQs starting 16 and up. The VIA chipset uses 4-bit IRQ register for internal interrupt routing, and therefore cannot handle IRQ numbers assigned to its devices. The patch corrects this problem by allowing PCI IRQs below 16.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PC Speaker driver's ->probe() routine doesn't even get called in the 64-bit kernels. The reason for that is that the arch code apparently has to explictly add a "pcspkr" platform device in order for the driver core to call the ->probe() routine. arch/i386/kernel/setup.c unconditionally adds a "pcspkr" device, but the x86_64 kernel has no code at all related to the PC Speaker. The patch below copies the relevant code from i386 to x86_64, which makes the PC Speaker work for me on x86_64.

Cell uses this to assign ids to SPUs, which are children of the CPU node. Existing users of of_node_to_nid() are altered to use of_node_to_nid_single(), which doesn't do the traversal. Export an attach_sysdev_to_node() function, allowing system devices (eg. SPUs) to link themselves into the numa topology in sysfs.

* | [PATCH] spufs: fix for CONFIG_NUMAJoel H Schopp2006-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on an older patch from Mike Kravetz <kravetz@us.ibm.com> We need to have a mem_map for high addresses in order to make fops->no_page work on spufs mem and register files. So far, we have used the memory_present() function during early bootup, but that did not work when CONFIG_NUMA was enabled. We now use the __add_pages() function to add the mem_map when loading the spufs module, which is a lot nicer.

* | [PATCH] uml: export symbols added by GCC hardenedPaolo 'Blaisorblade' Giarrusso2006-05-01
| | | | | | | | | | | | | | | | | | | | | | | | GCC hardened introduces additional symbol refererences (for the canary and friends), also in modules - add weak export_symbols for them. We already tested that the weak declaration creates no problem on both GCC's providing the function definition and on GCC's which don't provide it.
