Subject: [PATCH v3 0/6] um: Output messages to stderr and support quiet option

Hello,

Here is version 3 of um-quiet series. In this version
I just fixed some printf format issues.

V2 is here.

 https://lkml.org/lkml/2017/5/8/35

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 v2:
  - Cast rlim_min/max to unsigned long long explicitly
    for avoiding printf-format warning.
  - Fix printf format in physmem.c so that it matches
    the type of arguments.

Thank you,

---

      um: Use printk instead of printf in make_uml_dir
      um: Add os_info() for pre-boot information messages
      um: Use os_info for the messages on normal path
      um: Add os_warn() for pre-boot warning/error messages
      um: Use os_warn to print out pre-boot warning/error messages
      um: console: Ignore console= option
