2008-04-28hugetlbfs: common code update for s390Gerald Schaefer
Huge ptes have a special type on s390 and cannot be handled with the standard pte functions in certain cases, e.g. because of a different location of the invalid bit. This patch adds some new architecture- specific functions to hugetlb common code, as a prerequisite for the s390 large page support. This won't affect other architectures in functionality, but I need to add some new dummy inline functions to the headers.

2008-04-28hugetlbfs: add missing TLB flush to hugetlb_cow()Gerald Schaefer
A cow break on a hugetlbfs page with page_count > 1 will set a new pte with set_huge_pte_at(), w/o any tlb flush operation. The old pte will remain in the tlb and subsequent write access to the page will result in a page fault loop, for as long as it may take until the tlb is flushed from somewhere else. This patch introduces an architecture-specific huge_ptep_clear_flush() function, which is called before the the set_huge_pte_at() in hugetlb_cow(). ATTENTION: This is just a nop on all architectures for now, the s390 implementation will come with our large page patch later. Other architectures should define their own huge_ptep_clear_flush() if needed.

2008-04-28hugetlbfs: architecture header cleanupGerald Schaefer
This patch moves all architecture functions for hugetlb to architecture header files (include/asm-foo/hugetlb.h) and converts all macros to inline functions. It also removes (!) ARCH_HAS_HUGEPAGE_ONLY_RANGE, ARCH_HAS_HUGETLB_FREE_PGD_RANGE, ARCH_HAS_PREPARE_HUGEPAGE_RANGE, ARCH_HAS_SETCLEAR_HUGE_PTE and ARCH_HAS_HUGETLB_PREFAULT_HOOK. Getting rid of the ARCH_HAS_xxx #ifdef and macro fugliness should increase readability and maintainability, at the price of some code duplication. An asm-generic common part would have reduced the loc, but we would end up with new ARCH_HAS_xxx defines eventually.

2008-04-28mm: introduce pte_special pte bitNick Piggin
s390 for one, cannot implement VM_MIXEDMAP with pfn_valid, due to their memory model (which is more dynamic than most). Instead, they had proposed to implement it with an additional path through vm_normal_page(), using a bit in the pte to determine whether or not the page should be refcounted: vm_normal_page() { ... if (unlikely(vma->vm_flags & (VM_PFNMAP|VM_MIXEDMAP))) { if (vma->vm_flags & VM_MIXEDMAP) { #ifdef s390 if (!mixedmap_refcount_pte(pte)) return NULL; #else if (!pfn_valid(pfn)) return NULL; #endif goto out; } ... } This is fine, however if we are allowed to use a bit in the pte to determine refcountedness, we can use that to _completely_ replace all the vma based schemes. So instead of adding more cases to the already complex vma-based scheme, we can have a clearly seperate and simple pte-based scheme (and get slightly better code generation in the process): vm_normal_page() { #ifdef s390 if (!mixedmap_refcount_pte(pte)) return NULL; return pte_page(pte); #else ... #endif } And finally, we may rather make this concept usable by any architecture rather than making it s390 only, so implement a new type of pte state for this. Unfortunately the old vma based code must stay, because some architectures may not be able to spare pte bits. This makes vm_normal_page a little bit more ugly than we would like, but the 2 cases are clearly seperate. So introduce a pte_special pte state, and use it in mm/memory.c. It is currently a noop for all architectures, so this doesn't actually result in any compiled code changes to mm/memory.o. BTW: I haven't put vm_normal_page() into arch code as-per an earlier suggestion. The reason is that, regardless of where vm_normal_page is actually implemented, the *abstraction* is still exactly the same. Also, while it depends on whether the architecture has pte_special or not, that is the only two possible cases, and it really isn't an arch specific function -- the role of the arch code should be to provide primitive functions and accessors with which to build the core code; pte_special does that. We do not want architectures to know or care about vm_normal_page itself, and we definitely don't want them being able to invent something new there out of sight of mm/ code. If we made vm_normal_page an arch function, then we have to make vm_insert_mixed (next patch) an arch function too. So I don't think moving it to arch code fundamentally improves any abstractions, while it does practically make the code more difficult to follow, for both mm and arch developers, and easier to misuse.

2008-04-27sparc: Remove old style signal frame support.David S. Miller
Back around the same time we were bootstrapping the first 32-bit sparc Linux kernel with a SunOS userland, we made the signal frame match that of SunOS. By the time we even started putting together a native Linux userland for 32-bit Sparc we realized this layout wasn't sufficient for Linux's needs. Therefore we changed the layout, yet kept support for the old style signal frame layout in there. The detection mechanism is that we had sys_sigaction() start passing in a negative signal number to indicate "new style signal frames please". Anyways, no binaries exist in the world that use the old stuff. In fact, I bet Jakub Jelinek and myself are the only two people who ever had such binaries to be honest. So let's get rid of this stuff. I added an assertion using WARN_ON_ONCE() that makes sure 32-bit applications are passing in that negative signal number still. Signed-off-by: David S.

2008-04-23[SPARC64]: Store magic cookie and trap type in pt_regs.David S. Miller
This sets us up for several simplifications and facilities: 1) The magic cookie lets us identify trap frames more accurately in stack backtraces. 2) The trap type lets us simplify all of the "are we in a syscall" state management and checks. 3) We can now see if a task off the cpu is sleeping in a system call or not. In fact, we can see what trap it is sleeping in whatever the type. The utrace guys will use this. Based upon some discussions with Roland McGrath. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-04-02kvm: provide kvm.h for all architecture: fixes headers_installChristian Borntraeger
Currently include/linux/kvm.h is not considered by make headers_install, because Kbuild cannot handle " unifdef-$(CONFIG_FOO) += foo.h. This problem was introduced by commit fb56dbb31c4738a3918db81fd24da732ce3b4ae6 Author: Avi Kivity <avi@qumranet.com> Date: Sun Dec 2 10:50:06 2007 +0200 KVM: Export include/linux/kvm.h only if $ARCH actually supports KVM Currently, make headers_check barfs due to <asm/kvm.h>, which <linux/kvm.h> includes, not existing. Rather than add a zillion <asm/kvm.h>s, export kvm. only if the arch actually supports it. Signed-off-by: Avi Kivity <avi@qumranet.com> which makes this an 2.6.25 regression. One way of solving the issue is to enhance Kbuild, but Avi and David conviced me, that changing headers_install is not the way to go. This patch changes the definition for linux/kvm.h to unifdef-y. If  unifdef-y is used for linux/kvm.h "make headers_check" will fail on all architectures without asm/kvm.h. Therefore, this patch also provides asm/kvm.h on all architectures.

2008-03-24[SPARC64]: Make save_stack_trace() more efficient.David S. Miller
Doing a 'flushw' every stack trace capture creates so much overhead that it makes lockdep next to unusable. We only care about the frame pointer chain and the function caller program counters, so flush those by hand to the stack frame. This is significantly more efficient than a 'flushw' because: 1) We only save 16 bytes per active register window to the stack. 2) This doesn't push the entire register window context of the current call chain out of the cpu, forcing register window fill traps as we return back down. Note that we can't use 'restore' and 'save' instructions to move around the register windows because that wouldn't work on Niagara processors. They optimize 'save' into a new register window by simply clearing out the registers instead of pulling them in from the on-chip register window backing store. Based upon a report by Tom Callaway.

2008-03-21[SPARC64]: Remove most limitations to kernel image size.David S. Miller
Currently kernel images are limited to 8MB in size, and this causes problems especially when enabling features that take up a lot of kernel image space such as lockdep. The code now will align the kernel image size up to 4MB and map that many locked TLB entries. So, the only practical limitation is the number of available locked TLB entries which is 16 on Cheetah and 64 on pre-Cheetah sparc64 cpus. Niagara cpus don't actually have hw locked TLB entry support. Rather, the hypervisor transparently provides support for "locked" TLB entries since it runs with physical addressing and does the initial TLB miss processing. Fully utilizing this change requires some help from SILO, a patch for which will be submitted to the maintainer. Essentially, SILO will only currently map up to 8MB for the kernel image and that needs to be increased. Note that neither this patch nor the SILO bits will help with network booting. The openfirmware code will only map up to a certain amount of kernel image during a network boot and there isn't much we can to about that other than to implemented a layered network booting facility. Solaris has this, and calls it "wanboot" and we may implement something similar at some point. Signed-off-by: David S. Miller <davem@davemloft.net>
