2014-05-03sparc64: Give more detailed information in {pgd,pmd}_ERROR() and kill ↵David S. Miller
pte_ERROR(). pte_ERROR() is not used anywhere, delete it. For pgd_ERROR() and pmd_ERROR(), output something similar to x86, giving the address of the pgd/pmd as well as it's value. Also provide the caller, since these macros are invoked from pgd_clear_bad() and pmd_clear_bad() which provides little context as to what high level operation was occuring when the BAD state was detected.

2014-05-03sparc64: Add basic validations to {pud,pmd}_bad().David S. Miller
Instead of returning false we should at least check the most basic things, otherwise page table corruptions will be very difficult to debug. PMD and PTE tables are of size PAGE_SIZE, so none of the sub-PAGE_SIZE bits should be set. We also complement this with a check that the physical address the pud/pmd points to is valid memory. PowerPC was used as a guide while implementating this. Signed-off-by: David S. Miller <davem@davemloft.net>

2014-05-03sparc64: Fix range check in kern_addr_valid().David S. Miller
In commit b2d438348024b75a1ee8b66b85d77f569a5dfed8 ("sparc64: Make PAGE_OFFSET variable."), the MAX_PHYS_ADDRESS_BITS value was increased (to 47). This constant reference to '41UL' was missed. Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-03sparc64: Fix top-level fault handling bugs.David S. Miller
Make get_user_insn() able to cope with huge PMDs. Next, make do_fault_siginfo() more robust when get_user_insn() can't actually fetch the instruction. In particular, use the MMU announced fault address when that happens, instead of calling compute_effective_address() and computing garbage. Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-03sparc64: Handle 32-bit tasks properly in compute_effective_address().David S. Miller

2014-05-03sparc64: Fix bugs in get_user_pages_fast() wrt. THP.David S. Miller
The large PMD path needs to check _PAGE_VALID not _PAGE_PRESENT, to decide if it needs to bail and return 0. pmd_large() should therefore just check _PAGE_PMD_HUGE. Calls to gup_huge_pmd() are guarded with a check of pmd_large(), so we just need to add a valid bit check. Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-03sparc64: Fix huge PMD invalidation.David S. Miller
On sparc64 "present" and "valid" are seperate PTE bits, this allows us to naturally distinguish between the user explicitly asking for PROT_NONE with mprotect() and other situations. However we weren't handling this properly in the huge PMD paths. First of all, the page table walker in the TSB miss path only checks for _PAGE_PMD_HUGE. So the generic pmdp_invalidate() would clear _PAGE_PRESENT but the TLB miss paths would still load it into the TLB as a valid huge PMD. Fix this by clearing the valid bit in pmdp_invalidate(), and also checking the valid bit in USER_PGTABLE_CHECK_PMD_HUGE using "brgez" since _PAGE_VALID is bit 63 in both the sun4u and sun4v pte layouts.

2014-05-03sparc64: Fix executable bit testing in set_pmd_at() paths.David S. Miller
This code was mistakenly using the exec bit from the PMD in all cases, even when the PMD isn't a huge PMD. If it's not a huge PMD, test the exec bit in the individual ptes down in tlb_batch_pmd_scan(). Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-03sparc64: Normalize NMI watchdog logging and behavior.David S. Miller
Bring this code in line with the perf based generic NMI watchdog in kernel/watchdog.c (which we should convert over to at some point). In particular, don't do anything super fancy when the watchdog triggers, and specifically don't do a do_exit() which only makes things worse. Either panic(), or WARN(). The latter of which will do all of the actions such as give us a stack backtrace. Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-02sparc32: clean up io_32.hSam Ravnborg
After introducing asm-generic/io.h a few things could still be cleaned up o Drop useless macro indirection for sbus_* io access methods They were in the past used to hide casts between long and pointers but this is no longer so o Fix function definitions for sbus memory functions so return value appear on same line as function name Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull CPU hotplug notifiers registration fixes from Rafael Wysocki: "The purpose of this single series of commits from Srivatsa S Bhat (with a small piece from Gautham R Shenoy) touching multiple subsystems that use CPU hotplug notifiers is to provide a way to register them that will not lead to deadlocks with CPU online/offline operations as described in the changelog of commit 93ae4f978ca7f ("CPU hotplug: Provide lockless versions of callback registration functions"). The first three commits in the series introduce the API and document it and the rest simply goes through the users of CPU hotplug notifiers and converts them to using the new method" * tag 'cpu-hotplug-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (52 commits) net/iucv/iucv.c: Fix CPU hotplug callback registration net/core/flow.c: Fix CPU hotplug callback registration mm, zswap: Fix CPU hotplug callback registration mm, vmstat: Fix CPU hotplug callback registration profile: Fix CPU hotplug callback registration trace, ring-buffer: Fix CPU hotplug callback registration xen, balloon: Fix CPU hotplug callback registration hwmon, via-cputemp: Fix CPU hotplug callback registration hwmon, coretemp: Fix CPU hotplug callback registration thermal, x86-pkg-temp: Fix CPU hotplug callback registration octeon, watchdog: Fix CPU hotplug callback registration oprofile, nmi-timer: Fix CPU hotplug callback registration intel-idle: Fix CPU hotplug callback registration clocksource, dummy-timer: Fix CPU hotplug callback registration drivers/base/topology.c: Fix CPU hotplug callback registration acpi-cpufreq: Fix CPU hotplug callback registration zsmalloc: Fix CPU hotplug callback registration scsi, fcoe: Fix CPU hotplug callback registration scsi, bnx2fc: Fix CPU hotplug callback registration scsi, bnx2i: Fix CPU hotplug callback registration ...
