commit 97d69b16cb973e04ea5309b9cb4356aa6b42c54e
Author: Coly Li <[email protected]>
Date: Wed Apr 14 13:46:36 2021 +0800

bcache: add initial data structures for nvm pages

contains this code:

+#if (__BITS_PER_LONG != 64)
+ #error "Non-64bit platform is not supported"
+#endif

This breaks the build on arm and other 32-bit systems:

HDRTEST usr/include/linux/bcache-nvm.h
In file included from <command-line>:32:
./usr/include/linux/bcache-nvm.h:109:3: error: #error "Non-64bit platform is not supported"
#error "Non-64bit platform is not supported"
^~~~~
