[Suggest] arch: metag: compiler: Are they compiler's issues?

[Chen Gang]

Helllo Maintainers:

When compile metag with allmodconfig, I met the 2 kinds of issues, I
guess they are compiler's issues, please help check, thanks.


Issue 1: compiler report the issue, but after check the related kernel
source code, I can not find any issues.

    CC [M]  drivers/isdn/hisax/s0box.o
  drivers/isdn/hisax/hscx_irq.c: In function 'hscx_fill_fifo':
  /upstream/linux-next/arch/metag/include/asm/io.h:62: error: 'asm' operand requires impossible reload
  make[3]: *** [drivers/isdn/hisax/s0box.o] Error 1
  make[2]: *** [drivers/isdn/hisax] Error 2
  make[1]: *** [drivers/isdn] Error 2
  make: *** [drivers] Error 2


Issue 2: they are about structure variables alignment, I guess, the
compiler can not notice about the "#pragma pack()" correctly.

    CC [M]  drivers/staging/lustre/lustre/lov/lov_pack.o
  drivers/staging/lustre/lustre/lov/lov_pack.c: In function 'lov_getstripe':

Making cross-compiler:

  git clone git://github.com/img-meta/metag-buildroot.git metag-core-2013.11
  make meta2_defconfig.
  "cd metag-core-2013.11; cp -r output/host/usr/* /usr/"


Welcome any additional suggestions, discussions or completions.

Thanks.
