This patch lets the early real mode decompressor parse the kernel
command line and look for the 'quiet' option. When 'quiet' is passed
we suppress the "Decompressing Linux... Parsing ELF... done." messages.

This is in line with how the rest of the kernel suppresses informational
debug spew when quiet is given.

You know... we already have a command-line parser in the real-mode part of the boot code, and it already extracts the "quiet" option: we should be able to do this by passing a bit in "loadflags" (bit 5 suggested.) This would have the additional benefit of making it really easy for hypervisors that don't support writing to the screen at all to disable those messages.

What do you think?
