Subject: 3w-xxxx: Pass through compat mode ioctls
X-Git-Tag: v4.5-rc1~17^2^2~4
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=4f44f35dd8cf0818c51f399611ef868ebfdaccba;p=users%2Fjedix%2Flinux-maple.git

3w-xxxx: Pass through compat mode ioctls

This allows 32-bit userspace tools (tw_cli, smartctl) to work on a
64-bit system.  The command buffer is opaque to us, so, no word size
problems.
