      inflate: refactor inflate malloc code · 2d6ffcca
      Thomas Petazzoni 提交于
      Inflate requires some dynamic memory allocation very early in the boot
      process and this is provided with a set of four functions:
      malloc/free/gzip_mark/gzip_release.
      
      The old inflate code used a mark/release strategy rather than implement
      free.  This new version instead keeps a count on the number of outstanding
      allocations and when it hits zero, it resets the malloc arena.
      
      This allows removing all the mark and release implementations and unifying
      all the malloc/free implementations.
      
      The architecture-dependent code must define two addresses:
       - free_mem_ptr, the address of the beginning of the area in which
         allocations should be made
       - free_mem_end_ptr, the address of the end of the area in which
         allocations should be made. If set to 0, then no check is made on
         the number of allocations, it just grows as much as needed
      
      The architecture-dependent code can also provide an arch_decomp_wdog()
      function call.  This function will be called several times during the
      decompression process, and allow to notify the watchdog that the system is
      still running.  If an architecture provides such a call, then it must
      define ARCH_HAS_DECOMP_WDOG so that the generic inflate code calls
      arch_decomp_wdog().
      
      Work initially done by Matt Mackall, updated to a recent version of the
      kernel and improved by me.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
