From: Arnd Bergmann arnd@arndb.de
commit fbdf0e28d061708cf18ba0f8e0db5360dc9a15b9 upstream.
I got a warning about broken code on ARM64 with 64K pages:
drivers/net/vmxnet3/vmxnet3_drv.c: In function 'vmxnet3_rq_init': drivers/net/vmxnet3/vmxnet3_drv.c:1679:29: error: large integer implicitly truncated to unsigned type [-Werror=overflow] rq->buf_info[0][i].len = PAGE_SIZE;
'len' here is a 16-bit integer, so this clearly won't work. I don't think this driver is used much on anything other than x86, so there is no need to fix this properly and we can work around it with a Kconfig dependency to forbid known-broken configurations. qemu in theory supports it on other architectures too, but presumably only for compatibility with x86 guests that also run on vmware.
CONFIG_PAGE_SIZE_64KB is used on hexagon, mips, sh and tile, the other symbols are architecture-specific names for the same thing.
