[PATCH 0/2] m32r: fix build failure

[Sudip Mukherjee]

Hi Andrew,

m32r allmodconfig was failing for quite some time.

The first error being:
In file included from ../include/linux/kvm_para.h:4:0,
		 from ../kernel/watchdog.c:26:
../include/uapi/linux/kvm_para.h:30:26: fatal error: asm/kvm_para.h: No such file or directory

patch 1/2 will address this.

After fixing this some more errors surfaced which led to the missing
helpers.

The build still fails for one of the media driver. But atleast with this
series the first few reasons of the failures will be fixed.

Sending to you as m32r architecture is orphan.

[PATCH 1/2] m32r: fix build failure

[Sudip Mukherjee]

m32r allmodconfig is failing with:
In file included from ../include/linux/kvm_para.h:4:0,
                 from ../kernel/watchdog.c:26:
../include/uapi/linux/kvm_para.h:30:26: fatal error: asm/kvm_para.h: No such file or directory

The kvm_para.h was not included in the build.

[PATCH 2/2] m32r: add io*_rep helpers

[Sudip Mukherjee]

m32r allmodconfig was failing with the error:
error: implicit declaration of function 'read'

On checking io.h it turned out that 'read' is not defined but 'readb' is
defined and 'ioread8' will then obviously mean 'readb'.

At the same time some of the helper functions ioreadN_rep() and
iowriteN_rep() were missing which also led to the build failure.

After the change from read to readb the build has been verified with a
defconfig build.
