Hexagon fails to build after the final patch that makes CONFIG_HAS_IOPORT
optional:
In file included from arch/hexagon/include/asm/io.h:328:
include/asm-generic/io.h:854:18: error: static declaration of 'ioread8' follows non-static declaration
854 | static inline u8 ioread8(const volatile void __iomem *addr)
| ^
include/asm-generic/io.h:853:17: note: expanded from macro 'ioread8'
853 | #define ioread8 ioread8
| ^
include/asm-generic/iomap.h:29:21: note: previous declaration is here
29 | extern unsigned int ioread8(const void __iomem *);
| ^
As it turns out, most of its asm/io.h and lib/io.c files is redundant now,
and just removing all that makes it build again.
As with the other architectures, defining the __raw_readl()/__raw_writel()
type functions instead of the non-__raw ones is better here for consistency.

On some platforms, there is currently no way for the boot loader
|
|
to pass arguments to the kernel. For these, you should supply some
|
|
command-line options at build time by entering them here. At a
|
|
minimum, you should specify the memory size and the root device
|
|
(e.g., mem=64M root=/dev/nfs).

This allows you to specify the maximum number of CPUs which this
|
|
kernel will support. The maximum supported value is 6 and the
|
|
minimum value which makes sense is 2.
|
|
|
|
This is purely to save memory - each supported CPU adds
|
|
approximately eight kilobytes to the kernel image.
