Subject: Revert "VT: Use macros to define ioctls"
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7bc4244c882a7d7d79f4afefc50893244eb11d07;p=linux.git
Revert "VT: Use macros to define ioctls"
This reverts commit 8c467f3300591a206fa8dcc6988d768910799872.
Turns out this breaks many architectures as the vt ioctls do not all
match up everywhere due to historical reasons, so the original commit is
invalid for many values.
