2009-10-29ARM: Fix errata 411920 workaroundsRussell King
Errata 411920 indicates that any "invalidate entire instruction cache" operation can fail if the right conditions are present. This is not limited just to those operations in flush.c, but elsewhere. Place the workaround in the already existing __flush_icache_all() function instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-10-29ARM: Fix sparsemem with SPARSEMEM_EXTREME enabledRussell King
When SPARSEMEM_EXTREME is enabled, memory_present() wants to use bootmem to allocate data structures. However, we call memory_present() after declaring memory to bootmem, but before we've reserved areas. This leads to sparsemem data structures being overwritten later in the kernel's initialization (when slab initializes.) Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2009-10-29[S390] smp: fix sigp sense handlingHeiko Carstens
sigp sense only returns the status of a cpu if it is non zero. If the status of the sensed cpu is all zeros condition code 0 (accpeted) is set and no status bits are returned. The current code however assumes that a status was returned and tests bits in it. This means uninitalized data is accessed with random results. Worst case is that the code that checks if cpu is offline on cpu hotplug assumes that the target cpu is offline while it is still running. This leads potentially to memory corruption since resources that are still needed by the target cpu will be freed and could be resused while still in use.

2009-10-29[S390] smp: fix sigp stop handlingHeiko Carstens
According to the architecture a cpu must not necessarily enter stopped state after completion of a sigp instruction with "stop" order code. So remove the BUG() statement after self sending sigp stop to avoid that it ever gets reached. Also add a sigp busy check to make sure that the order gets delivered.

2009-10-29[S390] smp: fix prefix handling of offlined cpusHeiko Carstens
Offlined cpus still have valid prefix register contents. Dumpers will store the register contents of a cpu to the location where its prefix register points to. For offlined cpus the area (lowcore) has been freed and the dumper would write the uninteresting contents of the offline cpu to a memory location which might be in use by some other component and destroy valueable information. To fix this set the prefix register of offline cpus to absolute address zero again. This prevents the current dumpers to write to random memory locations.

2009-10-27powerpc/ppc64: Use preempt_schedule_irq instead of preempt_scheduleBenjamin Herrenschmidt
Based on an original patch by Valentine Barshak <vbarshak@ru.mvista.com> Use preempt_schedule_irq to prevent infinite irq-entry and eventual stack overflow problems with fast-paced IRQ sources. This kind of problems has been observed on the PASemi Electra IDE controller. We have to make sure we are soft-disabled before calling preempt_schedule_irq and hard disable interrupts after that to avoid unrecoverable exceptions. This patch also moves the "clrrdi r9,r1,THREAD_SHIFT" out of the #ifdef CONFIG_PPC_BOOK3E scope, since r9 is clobbered and has to be restored in both cases.

2009-10-27sh: Fix hugetlbfs dependencies for SH-3 && MMU configurations.Paul Mundt
The hugetlb dependencies presently depend on SUPERH && MMU while the hugetlb page size definitions depend on CPU_SH4 or CPU_SH5. This unfortunately allows SH-3 + MMU configurations to enable hugetlbfs without a corresponding HPAGE_SHIFT definition, resulting in the build blowing up. As SH-3 doesn't support variable page sizes, we tighten up the dependenies a bit to prevent hugetlbfs from being enabled. These days we also have a shiny new SYS_SUPPORTS_HUGETLBFS, so switch to using that rather than adding to the list of corner cases in fs/Kconfig.

2009-10-26x86-64: Fix register leak in 32-bit syscall audtingJan Beulich
Restoring %ebp after the call to audit_syscall_exit() is not only unnecessary (because the register didn't get clobbered), but in the sysenter case wasn't even doing the right thing: It loaded %ebp from a location below the top of stack (RBP < ARGOFFSET), i.e. arbitrary kernel data got passed back to user mode in the register.

2009-10-26x86: crash_dump: Fix non-pae kdump kernel memory accessesJiri Slaby
Non-PAE 32-bit dump kernels may wrap an address around 4G and poke unwanted space. ptes there are 32-bit long, and since pfn << PAGE_SIZE may exceed this limit, high pfn bits are cropped and wrong address mapped by kmap_atomic_pfn in copy_oldmem_page. Don't allow this behavior in non-PAE kdump kernels by checking pfns passed into copy_oldmem_page. In the case of failure, userspace process gets EFAULT.

2009-10-26x86: Side-step lguest problem by only building cmpxchg8b_emu for pre-PentiumRusty Russell
Commit 79e1dd05d1a22 "x86: Provide an alternative() based cmpxchg64()" broke lguest, even on systems which have cmpxchg8b support. The emulation code gets used until alternatives get run, but it contains native instructions, not their paravirt alternatives. The simplest fix is to turn this code off except for 386 and 486 builds.

2009-10-26sh: Check for return_to_handler when unwinding the stackMatt Fleming
When CONFIG_FUNCTION_GRAPH_TRACER is enabled the function graph tracer may patch return addresses on the stack with the address of return_to_handler(). This really confuses the DWARF unwinder because it will try find the caller of return_to_handler(), not the caller of the real return address. So teach the DWARF unwinder how to find the real return address whenever it encounters return_to_handler(). This patch does not cope very well when multiple return addresses on the stack have been patched. To make it work properly it would require state to track how many return_to_handler()'s have been seen so that we'd know where to look in current->curr_ret_stack[]. So for now, instead of trying to handle this, just moan if more than one return address on the stack has been patched.
