2009-07-27mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()Benjamin Herrenschmidt
mm: Pass virtual address to [__]p{te,ud,md}_free_tlb() Upcoming paches to support the new 64-bit "BookE" powerpc architecture will need to have the virtual address corresponding to PTE page when freeing it, due to the way the HW table walker works. Basically, the TLB can be loaded with "large" pages that cover the whole virtual space (well, sort-of, half of it actually) represented by a PTE page, and which contain an "indirect" bit indicating that this TLB entry RPN points to an array of PTEs from which the TLB can then create direct entries. Thus, in order to invalidate those when PTE pages are deleted, we need the virtual address to pass to tlbilx or tlbivax instructions. The old trick of sticking it somewhere in the PTE page struct page sucks too much, the address is almost readily available in all call sites and almost everybody implemets these as macros, so we may as well add the argument everywhere. I added it to the pmd and pud variants for consistency.

Pull the initial preempt_count value into a single definition site. Maintainers for: alpha, ia64 and m68k, please have a look, your arch code is funny. The header magic is a bit odd, but similar to the KERNEL_DS one, CPP waits with expanding these macros until the INIT_THREAD_INFO macro itself is expanded, which is in arch/*/kernel/init_task.c where we've already included sched.h so we're good.

2009-06-28KVM: s390: Allow stfle instruction in the guestChristian Borntraeger
2.6.31-rc introduced an architecture level set checker based on facility bits. e.g. if the kernel is compiled to run only on z9, several facility bits are checked very early and the kernel refuses to boot if a z9 specific facility is missing. Until now kvm on s390 did not implement the store facility extended (STFLE) instruction. A 2.6.31-rc kernel that was compiled for z9 or higher did not boot in kvm. This patch implements stfle. This patch should go in before 2.6.31. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2009-06-16kmap_types: make most arches use generic header fileRandy Dunlap
Convert most arches to use asm-generic/kmap_types.h. Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h, controlled by __WITH_KM_FENCE from each arch's kmap_types.h file. Would be nice to be able to add custom KM_types per arch, but I don't yet see a nice, clean way to do that. Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and 68k(tonyb). Note: avr32 should be able to remove KM_PTE2 (since it's not used) and then just use the generic kmap_types.h file. Get avr32 maintainer approval.

2009-06-11asm-generic: introduce asm/bitsperlong.hArnd Bergmann
This provides a reliable way for asm-generic/types.h and other files to find out if it is running on a 32 or 64 bit platform. We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.

2009-06-10KVM: s390: use hrtimer for clock wakeup from idle - v2Christian Borntraeger
This patch reworks the s390 clock comparator wakeup to hrtimer. The clock comparator is a per-cpu value that is compared against the TOD clock. If ckc <= TOD an external interrupt 1004 is triggered. Since the clock comparator and the TOD clock have a much higher resolution than jiffies we should use hrtimers to trigger the wakeup. This speeds up guest nanosleep for small values. Since hrtimers callbacks run in hard-irq context, I added a tasklet to do the actual work with enabled interrupts.

2009-03-26[S390] cpumask: use mm_cpumask() wrapperRusty Russell
Makes code futureproof against the impending change to mm->cpu_vm_mask. It's also a chance to use the new cpumask_ ops which take a pointer (the older ones are deprecated, but there's no hurry for arch code).
