      [PATCH] arm build fail: vfpsingle.c · 42d3fb5a
      Frederik Deweerdt 提交于
      It looks like Zach Brown's patch pr_debug-check-pr_debug-arguments
      worked as inteded. That is, it doesn't "allow completely incorrect code
      to build." :).
      
      The arm build fails with the following message:
        CC      arch/arm/vfp/vfpsingle.o
        arch/arm/vfp/vfpsingle.c: In function `__vfp_single_normaliseround':
        arch/arm/vfp/vfpsingle.c:201: error: `func' undeclared (first use in
        this function)
        arch/arm/vfp/vfpsingle.c:201: error: (Each undeclared identifier is
        reported only once

        make[1]: *** [arch/arm/vfp/vfpsingle.o] Error 1
        make: *** [arch/arm/vfp] Error 2
      
      The following patch fixes the issue by using func only when DEBUG is
      defined.

      [PATCH] restore parport_pc probing on powermac · 873ef76b
      Olaf Hering 提交于
      The last change for partport_pc did fix the common case for all PowerMacs,
      but it broke the case for PCI multiport IO cards.  In fact, the config
      option CONFIG_PARPORT_PC_SUPERIO=y lead to a hard crash when cups probed
      the parport driver.  It enables the winbond and smsc probing.
      
      Remove the PARPORT_BASE check again, parport_pc_find_nonpci_ports() will
      take care of it.  All powerpc configs should have
      CONFIG_PARPORT_PC_SUPERIO=n, the code did not find anything on the chrp
      boards we tested it on.

      [PATCH] VFS: Make filldir_t and struct kstat deal in 64-bit inode numbers · afefdbb2
      David Howells 提交于
      These patches make the kernel pass 64-bit inode numbers internally when
      communicating to userspace, even on a 32-bit system.  They are required
      because some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS
      for example.  The 64-bit inode numbers are then propagated to userspace
      automatically where the arch supports it.
      
      Problems have been seen with userspace (eg: ld.so) using the 64-bit inode
      number returned by stat64() or getdents64() to differentiate files, and
      failing because the 64-bit inode number space was compressed to 32-bits, and
      so overlaps occur.
      
      This patch:
      
      Make filldir_t take a 64-bit inode number and struct kstat carry a 64-bit
      inode number so that 64-bit inode numbers can be passed back to userspace.
      
      The stat functions then returns the full 64-bit inode number where
      available and where possible.  If it is not possible to represent the inode
      number supplied by the filesystem in the field provided by userspace, then
      error EOVERFLOW will be issued.
      
      Similarly, the getdents/readdir functions now pass the full 64-bit inode
      number to userspace where possible, returning EOVERFLOW instead when a
      directory entry is encountered that can't be properly represented.
      
      Note that this means that some inodes will not be stat'able on a 32-bit
      system with old libraries where they were before - but it does mean that
      there will be no ambiguity over what a 32-bit inode number refers to.
      
      Note similarly that directory scans may be cut short with an error on a
      32-bit system with old libraries where the scan would work before for the
      same reasons.
      
      It is judged unlikely that this situation will occur because modern glibc
      uses 64-bit capable versions of stat and getdents class functions
      exclusively, and that older systems are unlikely to encounter
      unrepresentable inode numbers anyway.

      [PATCH] replace cad_pid by a struct pid · 9ec52099
      Cedric Le Goater 提交于
      There are a few places in the kernel where the init task is signaled.  The
      ctrl+alt+del sequence is one them.  It kills a task, usually init, using a
      cached pid (cad_pid).
      
      This patch replaces the pid_t by a struct pid to avoid pid wrap around
      problem.  The struct pid is initialized at boot time in init() and can be
      modified through systctl with
      
      	/proc/sys/kernel/cad_pid
      
      [ I haven't found any distro using it ? ]
      
      It also introduces a small helper routine kill_cad_pid() which is used
      where it seemed ok to use cad_pid instead of pid 1.

      This adds the new kernel_execve function on all architectures that were using
      _syscall3() to implement execve.
      
      The implementation uses code from the _syscall3 macros provided in the
      unistd.h header file.  I don't have cross-compilers for any of these
      architectures, so the patch is untested with the exception of i386.
      
      Most architectures can probably implement this in a nicer way in assembly or
      by combining it with the sys_execve implementation itself, but this should do
      it for now.

      [PATCH] rename the provided execve functions to kernel_execve · 3db03b4a
      Arnd Bergmann 提交于
      Some architectures provide an execve function that does not set errno, but
      instead returns the result code directly.  Rename these to kernel_execve to
      get the right semantics there.  Moreover, there is no reasone for any of these
      architectures to still provide __KERNEL_SYSCALLS__ or _syscallN macros, so
      remove these right away.
