Raw Normal View History

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!

[SERIAL] typo: buad -> baud Replacing mistyped "buad" with "baud" where applicable. Signed-off-by: Horst Schirmeier <horst@schirmeier.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[ARM] Fix decompressor serial IO to give CRLF not LFCR As per the corresponding change to the serial drivers, arrange for ARM decompressors to give CRLF. Move the common putstr code into misc.c such that machines only need to supply "putc" and "flush" functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
