2008-07-23UML - Fix boot crashJeff Dike
My copying of linux/init.h didn't go far enough. The definition of __used singled out gcc minor version 3, but didn't care what the major version was. This broke when unit-at-a-time was added and gcc started throwing out initcalls. This results in an early boot crash when ptrace tries to initialize a process with an empty, uninitialized register set.

2008-07-23kgdb, powerpc: arch specific powerpc kgdb supportJason Wessel
This patch removes the old kgdb reminants from ARCH=powerpc and implements the new style arch specific stub for the common kgdb core interface. It is possible to have xmon and kgdb in the same kernel, but you cannot use both at the same time because there is only one set of debug hooks. The arch specific kgdb implementation saves the previous state of the debug hooks and restores them if you unconfigure the kgdb I/O driver. Kgdb should have no impact on a kernel that has no kgdb I/O driver configured. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>

2008-07-22x86: fix crash due to missing debugctlmsr on AMD K6-3Jan Kratochvil
currently if you use PTRACE_SINGLEBLOCK on AMD K6-3 (i586) it will crash. Kernel now wrongly assumes existing DEBUGCTLMSR MSR register there. Removed the assumption also for some other non-K6 CPUs but I am not sure there (but it can only bring small inefficiency there if my assumption is wrong).

2008-07-22x86: rename PTE_MASK to PTE_PFN_MASKJeremy Fitzhardinge
Rusty, in his peevish way, complained that macros defining constants should have a name which somewhat accurately reflects the actual purpose of the constant. Aside from the fact that PTE_MASK gives no clue as to what's actually being masked, and is misleadingly similar to the functionally entirely different PMD_MASK, PUD_MASK and PGD_MASK, I don't really see what the problem is. But if this patch silences the incessent noise, then it will have achieved its goal (TODO: write test-case).

2008-07-22x86: fix pte_flags() to only return flags, fix lguest (updated)Rusty Russell
(Jeremy said: rusty: use PTE_MASK rusty: use PTE_MASK rusty: use PTE_MASK When I asked: jsgf: does that include the NX flag? He responded eloquently: rusty: use PTE_MASK rusty: use PTE_MASK yes, it's the official constant of masking flags out of ptes ) Change a15af1c9ea2750a9ff01e51615c45950bad8221b 'x86/paravirt: add pte_flags to just get pte flags' removed lguest's private pte_flags() in favor of a generic one. Unfortunately, the generic one doesn't filter out the non-flags bits: this results in lguest creating corrupt shadow page tables and blowing up host memory. Since noone is supposed to use the pfn part of pte_flags(), it seems safest to always do the filtering.

With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype.

2008-07-22powerpc: Fix build bug with binutils < 2.18 and GCC < 4.2Segher Boessenkool
binutils < 2.18 has a bug that makes it misbehave when taking an ELF file with all segments at load address 0 as input. This happens when running "strip" on vmlinux, because of the AT() magic in this linker script. People using GCC >= 4.2 won't run into this problem, because the "build-id" support will put some data into the "notes" segment (at a non-zero load address). To work around this, we force some data into both the "dummy" segment and the kernel segment, so the dummy segment will get a non-zero load address. It's not enough to always create the "notes" segment, since if nothing gets assigned to it, its load address will be zero.

2008-07-22powerpc/eeh: Don't panic when EEH_MAX_FAILS is exceededMike Mason
This patch changes the EEH_MAX_FAILS action from panic to printing an error message. Panicking under under this condition is too harsh. Although performance will be affected and the device may not recover, the system is still running, which at the very least should allow for a more graceful shutdown. The patch also removes the msleep() within a spinlock, which can lead to a deadlock and is not recommended.

2008-07-22powerpc/cell: Add DMA_ATTR_WEAK_ORDERING dma attribute and use in Cell IOMMU ↵Mark Nelson
code Introduce a new dma attriblue DMA_ATTR_WEAK_ORDERING to use weak ordering on DMA mappings in the Cell processor. Add the code to the Cell's IOMMU implementation to use this code. Dynamic mappings can be weakly or strongly ordered on an individual basis but the fixed mapping has to be either completely strong or completely weak. This is currently decided by a kernel boot option (pass iommu_fixed=weak for a weakly ordered fixed linear mapping, strongly ordered is the default).

2008-07-22powerpc: Indicate which oprofile counters to use while in compat modeTorez Smith
While running on a system with new hardware and a kernel where the cpu_specs[] table does not recognize the new hardware, the identify_cpu() routine will select the default case as it searches through cpu_specs[] in an attempt to match the real PVR. Once the default case is selected, non of the oprofile counters and/or fields have been set up or defined. When identify_cpu() is called once more with the logical PVR, some of the cpu specific fields are replaced with the exception of the oprofile related ones. However, in the case where we have actually taken the default case while searching for the real PVR, we need to tell oprofile that we are now running in compatibility mode so it can pick up the correct counters. We do this by setting the oprofile_cpu_type field to be that taken from the cpu_specs[] for the cpu we are now emulating. This change will detect that we are now altering the real PVR and determine if we also need to update the oprofile_cpu_type field.
