* [PATCH] Set CONFIG_ZONE_DMA for arches with GENERIC_ISA_DMAChristoph Lameter2007-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | As Andi pointed out: CONFIG_GENERIC_ISA_DMA only disables the ISA DMA channel management. Other functionality may still expect GFP_DMA to provide memory below 16M. So we need to make sure that CONFIG_ZONE_DMA is set independent of CONFIG_GENERIC_ISA_DMA. Undo the modifications to mm/Kconfig where we made ZONE_DMA dependent on GENERIC_ISA_DMA and set theses explicitly in each arches Kconfig. Reviews must occur for each arch in order to determine if ZONE_DMA can be switched off. It can only be switched off if we know that all devices supported by a platform are capable of performing DMA transfers to all of memory (Some arches already support this: uml, avr32, sh sh64, parisc and IA64/Altix). In order to switch ZONE_DMA off conditionally, one would have to establish a scheme by which one can assure that no drivers are enabled that are only capable of doing I/O to a part of memory, or one needs to provide an alternate means of performing an allocation from a specific range of memory (like provided by alloc_pages_range()) and insure that all drivers use that call. In that case the arches alloc_dma_coherent() may need to be modified to call alloc_pages_range() instead of relying on GFP_DMA.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit e4f0ae0ea63caceff37a13f281a72652b7ea71ba. It's not wrong, but it's not right either, and everybody seems to agree that the right fix is probably to do the ccr3 write after the ccr4 one (and that we also should clean it up a bit). And after that we need to really validate that all the bits that we write to ccr4 actually do work. The old 2.6.19 code was insane, and basically didn't change ccr4 at all (even though it certainly looks like it was the *intent* to do so). So let's revert the change that may fix things, just because it's not what was actually ever tested when the code was written, even if it _was_ the intent. There's a discussion on http://lkml.org/lkml/2007/1/9/63 that was started by the patch that now gets reverted, and that discussion may well contain the proper long-term fix.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i386 boot/compressed/relocs checks for absolute symbols and warns about unexpected ones. If you build with modversions, you get ~2500 warnings about __crc_<symbol>. These suckers are really absolute symbols - we do _not_ want to modify them on relocation. They are generated by genksyms - EXPORT_... generates a weak alias, then genksyms produces an ld script with __crc_<symbol> = <checksum> and it's fed to ld to produce the final object file. Their only use is to match kernel and module at modprobe time; they _must_ be absolute. boot/compressed/relocs has a whitelist of known absolute symbols, but it doesn't know about __crc_... stuff. As the result, we get shitloads of false positives on any ld(1) version. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* | | [PATCH] i386: In assign_irq_vector look at all vectors before giving upEric W. Biederman2007-01-30
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the world was a simple and static place setting up irqs was easy. It sufficed to allocate a linux irq number and a find a free cpu vector we could receive that linux irq on. In those days it was a safe assumption that any allocated vector was actually in use so after one global pass through all of the vectors we would have none left. These days things are much more dynamic with interrupt controllers (in the form of MSI or MSI-X) appearing on plug in cards and linux irqs appearing and disappearing. As these irqs come and go vectors are allocated and freed, invalidating the ancient assumption that all allocated vectors stayed in use forever. So this patch modifies the vector allocator to walk through every possible vector before giving up, and to check to see if a vector is in use before assigning it. With these changes we stop leaking freed vectors and it becomes possible to allocate and free irq vectors all day long. This changed was modeled after the vector allocator on x86_64 where this limitation has already been removed. In essence we don't update the static variables that hold the position of the last vector we allocated until have successfully allocated another vector. This allows us to detect if we have completed one complete scan through all of the possible vectors. Acked-by: Auke Kok <auke-jan.h.kok@intel.com> Signed-off-by: Eric W.

* | [PATCH] i386 vDSO: use VM_ALWAYSDUMPRoland McGrath2007-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes core dumps to include the vDSO vma, which is left out now. It removes the special-case core writing macros, which were not doing the right thing for the vDSO vma anyway. Instead, it uses VM_ALWAYSDUMP in the vma; there is no need for the fixmap page to be installed. It handles the CONFIG_COMPAT_VDSO case by making elf_core_dump use the fake vma from get_gate_vma after real vmas in the same way the /proc/PID/maps code does. This changes core dumps so they no longer include the non-PT_LOAD phdrs from the vDSO. I made the change to add them in the first place, but in turned out that nothing ever wanted them there since the advent of NT_AUXV. It's cleaner to leave them out, and just let the phdrs inside the vDSO image speak for themselves.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I wouldn't mind if CONFIG_COMPAT_VDSO went away entirely. But if it's there, it should work properly. Currently it's quite haphazard: both real vma and fixmap are mapped, both are put in the two different AT_* slots, sysenter returns to the vma address rather than the fixmap address, and core dumps yet are another story. This patch makes CONFIG_COMPAT_VDSO disable the real vma and use the fixmap area consistently. This makes it actually compatible with what the old vdso implementation did.

With that, "nmi_watchdog=2" stops working for me on Intel Core 2 CPU based system. The problem is, setup_nmi_watchdog is called while parsing the boot option and identify_cpu is not done yet. So, the return value of nmi_known_cpu() is not valid at this point. So revert that check. This should not have any adverse effect as the nmi_known_cpu() check is done again later in enable_lapic_nmi_watchdog().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current PDA code, which went in in post 2.6.19 has a flaw in that it doesn't correctly cycle the GDT and %GS segment through the boot PDA, the CPU PDA and finally the per-cpu PDA. The bug generally doesn't show up if the boot CPU id is zero, but everything falls apart for a non zero boot CPU id. The basically kills voyager which is perfectly capable of doing non zero CPU id boots, so voyager currently won't boot without this. The fix is to be careful and actually do the GDT setups correctly.

I did those to supress the warnings generated by MODPOST. These warnings are visible only if CONFIG_RELOCATABLE=y. o CONFIG_RELOCATABLE compiles the kernel with --emit-relocs option.

Many of the functions in smpboot case are __devinit type and they in turn accesses text/data which if of type __cpuinit. Now if CONFIG_HOTPLUG=y and CONFIG_HOTPLUG_CPU=n then we end up in cases where a function in .text segment is calling another function in .init.text segment and MODPOST emits warning.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Relocatable bzImage support had got rid of CONFIG_PHYSICAL_START option thinking that now this option is not required as people can build a second kernel as relocatable and load it anywhere. So need of compiling the kernel for a custom address was gone. But Magnus uses vmlinux images for second kernel in Xen environment and he wants to continue to use it. o Restoring the CONFIG_PHYSICAL_START option for the time being. I think down the line we can get rid of it. Signed-off-by: Vivek Goyal <vgoyal@in.ibm.com> Cc: "Eric W.

Though the warning is accurate, all the callers of the flagged non __init function are __init, this is not a functional change.

At start guess_fsb function is guessing 200MHz FSB too. It is better to make it in this way because, thanks to this function, driver will fail for bogus FSB values caused by bogus multiplier value. For PowerSaver processors we can't depend on Max / MinMHzFSB because these values are only used for PowerSaver 2.0 and 3.0. Most processors on which Longhaul is used are PowerSaver 1.0 only. I'm changing code for older CPU's too, but not so much as previously, and this code was already used for Ezra. Using MinMHzBR for Ezra-T is outside spec. It is for voltage scaling purpose and don't have to be equal to minmult (but it is). Same for Nehemiah (it isn't for sure). Added mult - current multiplier value.
