Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! 2005-04-17 06:20:36 +08:00			`/*`

[PATCH] vgacon: make VGA_MAP_MEM take size, remove extra use VGA_MAP_MEM translates to ioremap() on some architectures. It makes sense to do this to vga_vram_base, because we're going to access memory between vga_vram_base and vga_vram_end. But it doesn't really make sense to map starting at vga_vram_end, because we aren't going to access memory starting there. On ia64, which always has to be different, ioremapping vga_vram_end gives you something completely incompatible with ioremapped vga_vram_start, so vga_vram_size ends up being nonsense. As a bonus, we often know the size up front, so we can use ioremap() correctly, rather than giving it a zero size. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: "Antonino A.
