Subject: [RFC PATCH v2 0/6] um: Output messages to stderr and support quiet option

Hello,

Here is version 2 of um-quiet series.

This series fixes some boot time printf output to stderr
by adding os_info() and os_warn(). The information-level
messages via os_info() are suppressed when "quiet" kernel
option is specified.
Also the last one allows user to pass "console=" option
to kernel.

Note that the output of --help and --version are still
sent to stdout since they are intentionally shown by
the user.

Changes from v1:
 - Introduce os_info() and os_warn() to replace most of
   printf() instead of reusing non_fatal().
 - Replace fprintf(stderr, ...) with os_warn() for error
   messages.

Thank you,

---
