Hi,

This is a patchset v2 to add dynamic memory allocator support
for nolibc after 2 RFCs, please review the changes carefully.

@@ Changelog:
---
   Link v1: https://lore.kernel.org/lkml/20220324073039.140946-1-ammarfaizi2@gnuweeb.org
   v1 -> v2:
     - Sync with Paul's tree.
     - Drop 2 patches that tried to remove register variables
       (comment from Willy).
     - Make the patch that replaces `asm` with `__asm__` the
       second patch (comment from Willy).

   Link RFC v2: https://lore.kernel.org/lkml/20220322102115.186179-1-ammarfaizi2@gnuweeb.org
   RFC v2 -> v1:
     - Rebase, sync with Paul's tree.
     - Add new 3 patches [PATCH 03/11], [PATCH 04/11], [PATCH 05/11].

     [PATCH 02/11]
     - Append Reviewed-by tag from Nick.
     - s/Removing/remove/

     [PATCH 06/11]
     - Use the same pattern for syscall6, regardless using GCC or Clang
      (comment from David).
     - Use appropriate constraints for syscall6 instead of always using
      register variables (comment from David).

     [PATCH 09/11]
     - Round up the malloc() allocation to 4096 (comment from David).
     - Don't realloc() if we still have enough memory to contain the
       requested new size (comment from David).
     - Fix conflict with getenv() fix (after rebase).

   Link RFC v1: https://lore.kernel.org/lkml/20220320093750.159991-1-ammarfaizi2@gnuweeb.org
   RFC v1 -> RFC v2:
    - Add 2 new patches [PATCH 5/8] and [PATCH 7/8].

    [PATCH 2/8]
    - Remove all `.global _start` for all build (GCC and Clang) instead of
      removing all `.weak _start` for clang build (Comment from Willy).

    [PATCH 3/8]
    - Fix %ebp saving method. Don't use redzone, i386 doesn't have a redzone
      (comment from David and Alviro).

    [PATCH 6/8]
    - Move container_of() and offsetof() macro to types.h with a
      separate patch (comment from Willy).

    [PATCH 8/8]
    - Update strdup and strndup implementation, use strlen and strnlen to get
      the string length first (comment from Willy and Alviro).
    - Fix the subject line prefix, it was "tools/include/string: ", it should be
      "tools/nolibc/string: ".
    - Update the commit message.
