      improve sys_newuname() for compat architectures · e28cbf22
      Christoph Hellwig 提交于
      On an architecture that supports 32-bit compat we need to override the
      reported machine in uname with the 32-bit value.  Instead of doing this
      separately in every architecture introduce a COMPAT_UTS_MACHINE define in
      <asm/compat.h> and apply it directly in sys_newuname().

      Add generic sys_ipc wrapper · baed7fc9
      Christoph Hellwig 提交于
      Add a generic implementation of the ipc demultiplexer syscall.  Except for
      s390 and sparc64 all implementations of the sys_ipc are nearly identical.
      
      There are slight differences in the types of the parameters, where mips
      and powerpc as the only 64-bit architectures with sys_ipc use unsigned
      long for the "third" argument as it gets casted to a pointer later, while
      it traditionally is an "int" like most other paramters.  frv goes even
      further and uses unsigned long for all parameters execept for "ptr" which
      is a pointer type everywhere.  The change from int to unsigned long for
      "third" and back to "int" for the others on frv should be fine due to the
      in-register calling conventions for syscalls (we already had a similar
      issue with the generic sys_ptrace), but I'd prefer to have the arch
      maintainers looks over this in details.
      
      Except for that h8300, m68k and m68knommu lack an impplementation of the
      semtimedop sub call which this patch adds, and various architectures have
      gets used - at least on i386 it seems superflous as the compat code on
      x86-64 and ia64 doesn't even bother to implement it.
