      remoteproc: qcom: fix initializers for qcom_mss_reg_res array · ec671b53
      Arnd Bergmann 提交于
      The recently added initialization is rather unusual because it uses a constructor for
      a variable-length array to assign a constant structure to a member that uses a fixed-length
      array. This confuses clang and breaks the build.
      
      drivers/remoteproc/qcom_q6v5_pil.c:1024:18: error: incompatible pointer types initializing 'const char *' with an expression of type
      :%s      'struct qcom_mss_reg_res [4]' [-Werror,-Wincompatible-pointer-types]
              .proxy_supply = (struct qcom_mss_reg_res[]) {
                              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      drivers/remoteproc/qcom_q6v5_pil.c:1024:18: warning: suggest braces around initialization of subobject [-Wmissing-braces]
              .proxy_supply = (struct qcom_mss_reg_res[]) {
                              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      
      We can either turn this constructor into a regular initializer by removing
      the 'struct qcom_mss_reg_res[])', or we can make the array variable length.
      
      The latter approach is used for the arrays of strings in the same structure,
      so let's use that here too.

      fix a fencepost error in pipe_advance() · b9dc6f65
      Al Viro 提交于
      The logics in pipe_advance() used to release all buffers past the new
      position failed in cases when the number of buffers to release was equal
      to pipe->buffers.  If that happened, none of them had been released,
      leaving pipe full.  Worse, it was trivial to trigger and we end up with
      pipe full of uninitialized pages.  IOW, it's an infoleak.

      coredump: Ensure proper size of sparse core files · 4d22c75d
      Dave Kleikamp 提交于
      If the last section of a core file ends with an unmapped or zero page,
      the size of the file does not correspond with the last dump_skip() call.
      gdb complains that the file is truncated and can be confusing to users.
      
      After all of the vma sections are written, make sure that the file size
      is no smaller than the current file position.
      
      This problem can be demonstrated with gdb's bigcore testcase on the
      sparc architecture.
