The variable 'KERNEL_ARCH' is actually a normalized version of 'ARCH'/'BR2_ARCH'. For example, 'arcle' and 'arceb' both become 'arc', just as all powerpc variants become 'powerpc'. It is presumably called 'KERNEL_ARCH' because the Linux kernel is typically the first place where support for a new architecture is added, and thus is the entity that defines the normalized name. However, the term 'KERNEL_ARCH' can also be interpreted as 'the architecture used by the kernel', which need not be exactly the same as 'the normalized name for a certain arch'. In particular, for cases where a 64-bit architecture is running a 64-bit kernel but 32-bit userspace. Examples include: * aarch64 architecture, with aarch64 kernel and 32-bit (ARM) userspace * x86_64 architecture, with x86_64 kernel and 32-bit (i386) userspace In such cases, the 'architecture used by the kernel' needs to refer to the 64-bit name (aarch64, x86_64), whereas all userspace applications need to refer the, potentially normalized, 32-bit name. This means that there need to be two different variables: KERNEL_ARCH: the architecture used by the kernel NORMALIZED_ARCH: the normalized name for the current userspace architecture At this moment, both will actually have the same content. But a subsequent patch will add basic support for situations described above, in which KERNEL_ARCH may become overwritten to the 64-bit architecture, while NORMALIZED_ARCH needs to remain the same (32-bit) case. This commit replaces use of KERNEL_ARCH where actually the userspace arch is needed. Places that use KERNEL_ARCH in combination with building of kernel modules are not touched. There may be cases where a package builds both a kernel module as userspace, in which case it may need to know about both KERNEL_ARCH and NORMALIZED_ARCH, for the case where they differ. But this is to be fixed on a per-need basis.
