parisc: Allow CONFIG_64BIT with ARCH=parisc
The previous patch triggered a build failure for the debian kernel, which has CONFIG_64BIT enabled, uses the CROSS_COMPILER environment variable and uses ARCH=parisc to configure the kernel for 64-bit support. This patch weakens the previous patch while keeping the recommended way to configure the kernel with: ARCH=parisc -> build 32-bit kernel ARCH=parisc64 -> build 64-bit kernel while adding the possibility for debian to configure a 64-bit kernel even if ARCH=parisc is set (PA8X00 CPU has to be selected and CONFIG_64BIT needs to be enabled). The downside of this patch is, that we now have a small window open again where people may get it wrong: if they enable CONFIG_64BIT and try to compile with a 32-bit compiler. Fixes: 3dcfb729 ("parisc: Make CONFIG_64BIT available for ARCH=parisc64 only") Signed-off-by:Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org> # 5.15+
