This broke because skb_trim no longer allows paged packets to be trimmed. Paged packets must be given to one of the pskb_trim functions instead. This patch adds a new pskb_trim_unique function to cover the IPv4/IPv6 datagram output path scenario and replaces the corresponding skb_trim calls with it.

But depending on the console driver (vgacon or fbcon for instance), that's bit 3 or bit 0. And there is no way for userland to know that, thus no way for userland to safely grab the screen content. So here is a (tested) patch: Add a VT_GETHIFONTMASK ioctl for knowing which bit is the 9th bit for VC text (vc_hi_font_mask field of the vc_data structure).
