After we ALIGN up the address we need to make sure we didn't overflow
and resulted in zero address. In that case, we need to make sure that
the returned address is greater than mmap_min_addr.
Also when doing top-down search the low_limit is not PAGE_SIZE but rather
max(PAGE_SIZE, mmap_min_addr). T

I often test all Kconfig commands for all architectures. To ease my
workflow, I want 'make defconfig' at least working without any cross
compiler.
Currently, arch/powerpc/Makefile checks CROSS_COMPILE to decide the
default defconfig source.
If CROSS_COMPILE is unset, it is likely to be the native

This patch does a final cleanup dropping the Kconfig GENERIC_CSUM

Hi,

Are you suggesting here to look at the ide-acpi.c sourc file available as
part of the driver code? In my original post I mentioned that I have
modified the ide-generic.c source file to use the IO port addresses and IRQ
numb
The ESAI_xCR_xWA is xCR's bit, not the xCCR's bit, driver set it to
wrong register, correct it.
