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

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:
