[PATCH] arch/unicore32/kernel/ksyms.c: remove several undefined exported symbols

[PATCH] arch/unicore32/kernel/ksyms.c: remove several undefined exported symbols

[Chen Gang]

For 'csum_partial_copy_nocheck()', it has default definition in
'asm-generic'.

For '__raw_reads?()' and '__raw_writes?()' are used by the drivers
which no relationship with allmodconfig for unicode32, the related
modules are:

  drivers/mmc/host/omap.c
  drivers/mtd/nand/atmel_nand.c
  drivers/mtd/nand/pxa3xx_nand.c
  drivers/usb/gadget/at91_udc.c

Others are only within some architectures (not kernel wide).


The related error with allmodconfig for unicode32:

Thanks Chen.
Need I add these patches to unicore32 repo?

Thank all of you for these 3 patches. Please help add them to the
related git tree (and/or related repo), when you have time, thanks.

And I will/should continue to fine another patches for unicore32 to let
it pass allmodconfig compiling under Linux. Hope I can finish within
next month (2014-04-30)


Thanks.
