The kernel patch applies to all platforms (it changes arch-independent sources).
But the bug doesn't occur on the other platforms: - x86 is 32bit userspace on a 32bit kernel - amd64 is 64bit userspace on a 64bit kernel.
The bug only appears when a 32bit userspace is used on a 64bit kernel - this is the powerpc64 platform.
So the kernel patch applies to all platforms, but it only fixes breakage specific for powerpc64.
