Anyone shed some light on this please?
There is a KERNEL CONFIG option "CONFIG_REGPARM=Y/N that some software build scripts check for, OSS for example. I have noticed that neither TC-7.2 x86 or x86_64 KERNEL CONFIG's use this option, in fact it doesn't even exist in the config files.
This option appears to be valid only for x86 kernels, from what I can tell x86_64 KERNELS don't use the option (calls go elsewhere..)
So is it only used in 32bit configs? and appears only if prompted by another option which = Y
