The high order 32 bits of the registers were never cleared, and garbage was sometimes calculated into the checksum. Fix this by clearing the high order 32 bits of these registers.

2009-08-11arch/ia64/Makefile: Remove -mtune=merced in IA64 kernel buildFenghua Yu1-5/+0
Between GCC version 3.4.0 and 4.3.3 (including 3.4.0 and 4.3.3), -mtune=merced is implemented in GCC. Starting from 4.4.0, -mtune=merced is deprecated. Even implemented in versions between 3.4.0 and 4.3.3, the -mtune=merced feature has been broken in some of the versions. For example, GCC 4.1.2 reports interanl tuning function errors during kernel building with -mtune=merced. Or GCC Bugzilla 16130 reports another -mtune=merced issue on GCC 3.4.1. So I would remove the -mtune=merced from IA64 kernel build. Without this option, kernel on Merced will remain the same except losing an unstable and out-of-date performance tunning feature. Since GCC version 3.4.0, -mtune=mckinley has been implemented. The -mtune=mckinley option functions the same as mtune=itanium2. And mtune=itanium2 is the default option. So we don't need to add mtune=mckinley either since its been the default option in any GCC version which implements this option. Signed-off-by: Fenghua Yu <fenghua.yu@intel.com>

2009-07-27mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()Benjamin Herrenschmidt2-9/+9
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.

It is generally agreed that it would be beneficial for u64 to be an unsigned long long on all architectures. ia64 (in common with several other 64-bit architectures) currently uses unsigned long. Migrating piecemeal is too painful; this giant patch fixes all compilation warnings and errors that come as a result of switching to use int-ll64.h. Note that userspace will still see __u64 defined as unsigned long. This is important as it affects C++ name mangling.

2009-06-16remove put_cpu_no_resched()Thomas Gleixner1-1/+1
put_cpu_no_resched() is an optimization of put_cpu() which unfortunately can cause high latencies. The nfs iostats code uses put_cpu_no_resched() in a code sequence where a reschedule request caused by an interrupt between the get_cpu() and the put_cpu_no_resched() can delay the reschedule for at least HZ. The other users of put_cpu_no_resched() optimize correctly in interrupt code, but there is no real harm in using the put_cpu() function which is an alias for preempt_enable(). The extra check of the preemmpt count is not as critical as the potential source of missing a reschedule. Debugged in the preempt-rt tree and verified in mainline.

2009-06-15[IA64] remove obsolete no_irq_typeThomas Gleixner3-3/+3
The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have been kept around for migration reasons. After more than two years it's time to remove them finally. This patch cleans up one of the remaining users. When all such patches hit mainline we can remove the defines and typedefs finally. Impact: cleanup convert the last remaining users to no_irq_chip Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Tony Luck <tony.luck@intel.com>

2009-06-12module: trim exception table on init free.Rusty Russell1-0/+26
It's theoretically possible that there are exception table entries which point into the (freed) init text of modules. These could cause future problems if other modules get loaded into that memory and cause an exception as we'd see the wrong fixup. The only case I know of is kvm-intel.ko (when CONFIG_CC_OPTIMIZE_FOR_SIZE=n). Amerigo fixed this long-standing FIXME in the x86 version, but this patch is more general. This implements trim_init_extable(); most archs are simple since they use the standard lib/extable.c sort code. Alpha and IA64 use relative addresses in their fixups, so thier trimming is a slight variation. Sparc32 is unique; it doesn't seem to define ARCH_HAS_SORT_EXTABLE, yet it defines its own sort_extable() which overrides the one in lib. It doesn't sort, so we have to mark deleted entries instead of actually trimming them.
