      MIPS: Use the entry point from the ELF file header · 27c524d1
      由 Maciej W. Rozycki 提交于 
      In order to fetch the correct entry point with the ISA bit included, for
use by non-ELF boot loaders, parse the output of `objdump -f' for the
start address recorded in the kernel executable itself, rather than
using `nm' to get the value of the `kernel_entry' symbol.

Sign-extend the address retrieved if 32-bit, so that execution is
correctly started on 64-bit processors as well.  The tool always prints
the entry point using either 8 or 16 hexadecimal digits, matching the
address width (aka class) of the ELF file, even in the presence of
leading zeros.

      MIPS: Expand help text to list generic defconfigs · cccd0b9a
      由 James Hogan 提交于 
      Expand the MIPS Makefile help text to list generic board names, generic
defconfigs, and legacy defconfigs which have been converted to generic
and are still usable.

Here's a snippet of the new "make ARCH=mips help" output:
  ...
  If you are targeting a system supported by generic kernels you may
  configure the kernel for a given architecture target like so:

  {micro32,32,64}{r1,r2,r6}{el,}_defconfig <BOARDS="list of boards">

  Where BOARDS is some subset of the following:
    boston
    ni169445
    ranchu
    sead-3
    xilfpga

  Specifically the following generic default configurations are
  supported:

  32r1_defconfig           - Build generic kernel for MIPS32 r1
  32r1el_defconfig         - Build generic kernel for MIPS32 r1 little endian
  32r2_defconfig           - Build generic kernel for MIPS32 r2
  32r2el_defconfig         - Build generic kernel for MIPS32 r2 little endian
  32r6_defconfig           - Build generic kernel for MIPS32 r6
  32r6el_defconfig         - Build generic kernel for MIPS32 r6 little endian
  64r1_defconfig           - Build generic kernel for MIPS64 r1
  64r1el_defconfig         - Build generic kernel for MIPS64 r1 little endian
  64r2_defconfig           - Build generic kernel for MIPS64 r2
  64r2el_defconfig         - Build generic kernel for MIPS64 r2 little endian
  64r6_defconfig           - Build generic kernel for MIPS64 r6
  64r6el_defconfig         - Build generic kernel for MIPS64 r6 little endian
  micro32r2_defconfig      - Build generic kernel for microMIPS32 r2
  micro32r2el_defconfig    - Build generic kernel for microMIPS32 r2 little endian

  The following legacy default configurations have been converted to
  generic and can still be used:

  sead3_defconfig          - Build 32r2el_defconfig BOARDS=sead-3
  sead3micro_defconfig     - Build micro32r2el_defconfig BOARDS=sead-3
  xilfpga_defconfig        - Build 32r2el_defconfig BOARDS=xilfpga

      unify {de,}mangle_poll(), get rid of kernel-side POLL... · 7a163b21
      由 Al Viro 提交于 
      except, again, POLLFREE and POLL_BUSY_LOOP.

With this, we finally get to the promised end result:

 - POLL{IN,OUT,...} are plain integers and *not* in __poll_t, so any
   stray instances of ->poll() still using those will be caught by
   sparse.

 - eventpoll.c and select.c warning-free wrt __poll_t

 - no more kernel-side definitions of POLL... - userland ones are
   visible through the entire kernel (and used pretty much only for
   mangle/demangle)

 - same behavior as after the first series (i.e. sparc et.al. epoll(2)
   working correctly).

      vfs: do bulk POLL* -> EPOLL* replacement · a9a08845
      由 Linus Torvalds 提交于 
      This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.
