      s390/pci: base support · cd248341
      Jan Glauber 提交于
      Add PCI support for s390, (only 64 bit mode is supported by hardware):
      - PCI facility tests
      - PCI instructions: pcilg, pcistg, pcistb, stpcifc, mpcifc, rpcit
      - map readb/w/l/q and writeb/w/l/q to pcilg and pcistg instructions
      - pci_iomap implementation
      - memcpy_fromio/toio
      - pci_root_ops using special pcilg/pcistg
      - device, bus and domain allocation

      s390/topology: fix core id vs physical package id mix-up · 658e5ce7
      Heiko Carstens 提交于
      The current topology code confuses core id vs physical package id.
      
      In other words /sys/devices/system/cpu/cpuX/topology/core_id
      displays the physical_package_id (aka socket id) instead of the
      core id.
      The physical_package_id sysfs attribute always displays "-1"
      instead of the socket id.
      
      Fix this mix-up with a small patch which defines and initializes
      topology_physical_package_id correctly and fixes the broken
      core id handling.

      s390/signal: set correct address space control · fa968ee2
      Martin Schwidefsky 提交于
      If user space is running in primary mode it can switch to secondary
      or access register mode, this is used e.g. in the clock_gettime code
      of the vdso. If a signal is delivered to the user space process while
      it has been running in access register mode the signal handler is
      executed in access register mode as well which will result in a crash
      most of the time.
      
      Set the address space control bits in the PSW to the default for the
      execution of the signal handler and make sure that the previous
      address space control is restored on signal return. Take care
      that user space can not switch to the kernel address space by
      modifying the registers in the signal frame.

      compat: move compat_siginfo_t definition to asm/compat.h · 751f409d
      Denys Vlasenko 提交于
      This is a preparatory patch for the introduction of NT_SIGINFO elf note.
      
      Make the location of compat_siginfo_t uniform across eight architectures
      which have it.  Now it can be pulled in by including asm/compat.h or
      linux/compat.h.
      
      Most of the copies are verbatim.  compat_uid[32]_t had to be replaced by
      __compat_uid[32]_t.  compat_uptr_t had to be moved up before
      compat_siginfo_t in asm/compat.h on a several architectures (tile already
      had it moved up).  compat_sigval_t had to be relocated from linux/compat.h
      to asm/compat.h.

      Make most arch asm/module.h files use asm-generic/module.h · 786d35d4
      David Howells 提交于
      Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
      ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
      into asm-generic/module.h for all arches bar MIPS.
      
      Also, use the generic definition mod_arch_specific where possible.
      
      To this end, I've defined three new config bools:
      
       (*) HAVE_MOD_ARCH_SPECIFIC
      
           Arches define this if they don't want to use the empty generic
           mod_arch_specific struct.
      
       (*) MODULES_USE_ELF_RELA
      
           Arches define this if their modules can contain RELA records.  This causes
           the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
           defined by the arch rather than have the core emit an error message.
      
       (*) MODULES_USE_ELF_REL
      
           Arches define this if their modules can contain REL records.  This causes
           the Elf_Rel mapping to be emitted and allows apply_relocate() to be
           defined by the arch rather than have the core emit an error message.
      
      Note that it is possible to allow both REL and RELA records: m68k and mips are
      two arches that do this.
      
      With this, some arch asm/module.h files can be deleted entirely and replaced
      with a generic-y marker in the arch Kbuild file.
      
      Additionally, I have removed the bits from m32r and score that handle the
      unsupported type of relocation record as that's now handled centrally.
