#     powerpc/64: Include cache.h directly in paca.h
#     
#     paca.h uses ____cacheline_aligned without directly including cache.h,
#     where it's defined.
#     
#     For Book3S builds that's OK because paca.h includes lppaca.h, and it
#     does include cache.h.
#     
#     But Book3E builds have been getting cache.h indirectly via printk.h,
#     which is dicey, and in fact that include was recently removed, leading
#     to build errors such as:
#     
#       ld: fs/isofs/dir.o:(.bss+0x0): multiple definition of `____cacheline_aligned'; fs/isofs/namei.o:(.bss+0x0): first defined here
#     
#     So include cache.h directly to fix the build error.
#     
#     Fixes: 534aa1dc975a ("printk: stop including cache.h from printk.h")
