2014-03-31Merge branch 'compat' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 compat wrapper rework from Heiko Carstens: "S390 compat system call wrapper simplification work. The intention of this work is to get rid of all hand written assembly compat system call wrappers on s390, which perform proper sign or zero extension, or pointer conversion of compat system call parameters. Instead all of this should be done with C code eg by using Al's COMPAT_SYSCALL_DEFINEx() macro. Therefore all common code and s390 specific compat system calls have been converted to the COMPAT_SYSCALL_DEFINEx() macro. In order to generate correct code all compat system calls may only have eg compat_ulong_t parameters, but no unsigned long parameters. Those patches which change parameter types from unsigned long to compat_ulong_t parameters are separate in this series, but shouldn't cause any harm. The only compat system calls which intentionally have 64 bit parameters (preadv64 and pwritev64) in support of the x86/32 ABI haven't been changed, but are now only available if an architecture defines __ARCH_WANT_COMPAT_SYS_PREADV64/PWRITEV64. System calls which do not have a compat variant but still need proper zero extension on s390, like eg "long sys_brk(unsigned long brk)" will get a proper wrapper function with the new s390 specific COMPAT_SYSCALL_WRAPx() macro: COMPAT_SYSCALL_WRAP1(brk, unsigned long, brk); which generates the following code (simplified): asmlinkage long sys_brk(unsigned long brk); asmlinkage long compat_sys_brk(long brk) { return sys_brk((u32)brk); } Given that the C file which contains all the COMPAT_SYSCALL_WRAP lines includes both linux/syscall.h and linux/compat.h, it will generate build errors, if the declaration of sys_brk() doesn't match, or if there exists a non-matching compat_sys_brk() declaration. In addition this will intentionally result in a link error if somewhere else a compat_sys_brk() function exists, which probably should have been used instead. Two more BUILD_BUG_ONs make sure the size and type of each compat syscall parameter can be handled correctly with the s390 specific macros. I converted the compat system calls step by step to verify the generated code is correct and matches the previous code. In fact it did not always match, however that was always a bug in the hand written asm code. In result we get less code, less bugs, and much more sanity checking" * 'compat' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (44 commits) s390/compat: add copyright statement compat: include linux/unistd.h within linux/compat.h s390/compat: get rid of compat wrapper assembly code s390/compat: build error for large compat syscall args mm/compat: convert to COMPAT_SYSCALL_DEFINE with changing parameter types kexec/compat: convert to COMPAT_SYSCALL_DEFINE with changing parameter types net/compat: convert to COMPAT_SYSCALL_DEFINE with changing parameter types ipc/compat: convert to COMPAT_SYSCALL_DEFINE with changing parameter types fs/compat: convert to COMPAT_SYSCALL_DEFINE with changing parameter types ipc/compat: convert to COMPAT_SYSCALL_DEFINE fs/compat: convert to COMPAT_SYSCALL_DEFINE security/compat: convert to COMPAT_SYSCALL_DEFINE mm/compat: convert to COMPAT_SYSCALL_DEFINE net/compat: convert to COMPAT_SYSCALL_DEFINE kernel/compat: convert to COMPAT_SYSCALL_DEFINE fs/compat: optional preadv64/pwrite64 compat system calls ipc/compat_sys_msgrcv: change msgtyp type from long to compat_long_t s390/compat: partial parameter conversion within syscall wrappers s390/compat: automatic zero, sign and pointer conversion of syscalls s390/compat: add sync_file_range and fallocate compat syscalls ...

2014-03-28x86: fix boot on uniprocessor systemsArtem Fetishev
On x86 uniprocessor systems topology_physical_package_id() returns -1 which causes rapl_cpu_prepare() to leave rapl_pmu variable uninitialized which leads to GPF in rapl_pmu_init(). See arch/x86/kernel/cpu/perf_event_intel_rapl.c. It turns out that physical_package_id and core_id can actually be retreived for uniprocessor systems too. Enabling them also fixes rapl_pmu code.

2014-03-26x86, efi: Abstract x86 efi_early callsMatt Fleming
The ARM EFI boot stub doesn't need to care about the efi_early infrastructure that x86 requires in order to do mixed mode thunking. So wrap everything up in an efi_call_early() macro. This allows x86 to do the necessary indirection jumps to call whatever firmware interface is necessary (native or mixed mode), but also allows the ARM folks to mask the fact that they don't support relocation in the boot stub and need to pass 'sys_table_arg' to every function.

2014-03-25Revert "xen: properly account for _PAGE_NUMA during xen pte translations"David Vrabel
This reverts commit a9c8e4beeeb64c22b84c803747487857fe424b68. PTEs in Xen PV guests must contain machine addresses if _PAGE_PRESENT is set and pseudo-physical addresses is _PAGE_PRESENT is clear. This is because during a domain save/restore (migration) the page table entries are "canonicalised" and uncanonicalised". i.e., MFNs are converted to PFNs during domain save so that on a restore the page table entries may be rewritten with the new MFNs on the destination. This canonicalisation is only done for PTEs that are present. This change resulted in writing PTEs with MFNs if _PAGE_PROTNONE (or _PAGE_NUMA) was set but _PAGE_PRESENT was clear. These PTEs would be migrated as-is which would result in unexpected behaviour in the destination domain. Either a) the MFN would be translated to the wrong PFN/page; b) setting the _PAGE_PRESENT bit would clear the PTE because the MFN is no longer owned by the domain; or c) the present bit would not get set. Symptoms include "Bad page" reports when munmapping after migrating a domain.

2014-03-24sparc64: Make sure %pil interrupts are enabled during hypervisor yield.David S. Miller
In arch_cpu_idle() we must enable %pil based interrupts before potentially invoking the hypervisor cpu yield call. As per the Hypervisor API documentation for cpu_yield: Interrupts which are blocked by some mechanism other that pstate.ie (for example %pil) are not guaranteed to cause a return from this service. It seems that only first generation Niagara chips are hit by this bug. My best guess is that later chips implement this in hardware and wake up anyways from %pil events, whereas in first generation chips the yield is implemented completely in hypervisor code and requires %pil to be enabled in order to wake properly from this call.

Since this macro is identical to pgprot_writecombine() and is only used in a single place, remove it completely to avoid confusion. On ARMv7+ processors, the coherent DMA mapping must be Normal NonCacheable (a.k.a. writecombine) to avoid mismatched hardware attribute aliases (with the kernel linear mapping as Normal Cacheable).

2014-03-24arm64: Implement custom mmap functions for dma mappingLaura Abbott
The current dma_ops do not specify an mmap function so maping falls back to the default implementation. There are at least two issues with using the default implementation: 1) The pgprot is always pgprot_noncached (strongly ordered) memory even with coherent operations 2) dma_common_mmap calls virt_to_page on the remapped non-coherent address which leads to invalid memory being mapped. Fix both these issue by implementing a custom mmap function which correctly accounts for remapped addresses and sets vm_pg_prot appropriately.
