While doing some easy cleanups on the sparc code I noticed that the CONFIG_SUN4 code seems to be worse than the rest - there were some "I don't know how it should work, but the current code definitely cannot work." places. And while I have seen people running Linux on machines like a SPARCstation 5 a few years ago I don't recall having seen sun4 machines, even less ones running Linux.

And stick the iommu archdata pointer into the generic OF device tree of_device struct as well. We still have to pass the sbus_bus object down into the routines so that the SBUS bus objects get the iommu cookies set properly. After drivers get converted to being pure OF drivers, that can go away. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This thing was completely pointless. Just find the OF device in the parent of drivers that want to program this device, and map the DMA regs inside such drivers too. This also moves the dummy claim_dma_lock() and release_dma_lock() implementation to floppy_32.h, which makes it handle this issue just like floppy_64.h does. Signed-off-by: NDavid S.

Stephen Rothwell noticed that I committed an earlier version of the patch that didn't have two things fixed: 1) irq_of_parse_and_map() should return "unsigned int" not "int" and it should return zero for "no irq" 2) irq_dispose_mapping() should be an inline function, not a macro, for type checking With feedback and suggestions from Anton Vorontsov.

On some platforms, the I2C controller is shared between the OS and OBP. OBP uses this I2C controller to access the EEPROM, and thus is programmed when the kernel calls prom_setprop(). Wrap such calls with the new of_set_property_mutex. Relevant I2C bus drivers can grab this mutex around top-level I2C operations to provide the proper protection. Signed-off-by: NDavid S.

This patch introduces the new syscall pipe2 which is like pipe but it also takes an additional parameter which takes a flag value. This patch implements the handling of O_CLOEXEC for the flag. I did not add support for the new syscall for the architectures which have a special sys_pipe implementation. I think the maintainers of those archs have the chance to go with the unified implementation but that's up to them. The implementation introduces do_pipe_flags. I did that instead of changing all callers of do_pipe because some of the callers are written in assembler. I would probably screw up changing the assembly code. To avoid breaking code do_pipe is now a small wrapper around do_pipe_flags. Once all callers are changed over to do_pipe_flags the old do_pipe function can be removed. The following test must be adjusted for architectures other than x86 and x86-64 and in case the syscall numbers changed. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #include <fcntl.h> #include <stdio.h> #include <unistd.h> #include <sys/syscall.h> #ifndef __NR_pipe2 # ifdef __x86_64__ # define __NR_pipe2 293 # elif defined __i386__ # define __NR_pipe2 331 # else # error "need __NR_pipe2" # endif #endif int main (void) { int fd[2]; if (syscall (__NR_pipe2, fd, 0) != 0) { puts ("pipe2(0) failed"); return 1; } for (int i = 0; i < 2; ++i) { int coe = fcntl (fd[i], F_GETFD); if (coe == -1) { puts ("fcntl failed"); return 1; } if (coe & FD_CLOEXEC) { printf ("pipe2(0) set close-on-exit for fd[%d]\n", i); return 1; } } close (fd[0]); close (fd[1]); if (syscall (__NR_pipe2, fd, O_CLOEXEC) != 0) { puts ("pipe2(O_CLOEXEC) failed"); return 1; } for (int i = 0; i < 2; ++i) { int coe = fcntl (fd[i], F_GETFD); if (coe == -1) { puts ("fcntl failed"); return 1; } if ((coe & FD_CLOEXEC) == 0) { printf ("pipe2(O_CLOEXEC) does not set close-on-exit for fd[%d]\n", i); return 1; } } close (fd[0]); close (fd[1]); puts ("OK"); return 0; } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: NUlrich Drepper <drepper@redhat.com> Acked-by: NDavide Libenzi <davidel@xmailserver.org> Cc: Michael Kerrisk <mtk.manpages@googlemail.com> Cc: <linux-arch@vger.kernel.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
