Thomas Pfaff 91c4313206 fbcon: fix color generation for monochrome framebuffer
The current attr_fgcol_ec / attr_bgcol_ec macros do a simple shift of bits
to get the color from vc_video_erase_char.  For a monochrome display
however the attribute does not contain any color, only attribute bits.
Furthermore the reverse bit is lost because it is shifted out, the
resulting color is always 0.

This can bee seen on a monochrome console either directly or by setting it
to inverse mode via "setterm -inversescreen on" .  Text is written with
correct color, fb_fillrects from a bit_clear / bit_clear_margins will get
wrong colors.

Antonino A. Daplas b73deed32d [PATCH] fbcon: Sanitize fbcon
Do not pass the structure display since fbcon is already keeping the pointer
to the current display.

Benjamin Herrenschmidt 1a9c3f78a3 [PATCH] Console rotation fixes
Remove bogus usage of test/set_bit() from fbcon rotation code and just
manipulate the bits directly.  This fixes an oops on powerpc among others
and should be faster.  Seems to work fine on the G5 here.
