[Qemu-devel] [PATCHv2 1/2] vl.c: Fix error messages when parsing maxmem parameters

2015-01-28 Thread Peter Krempa
Produce more human readable error messages and fix few spelling
mistakes.

Also remove a redundant check for the max memory size.

Signed-off-by: Peter Krempa pkre...@redhat.com

Notes:
Version 2:
- fixed spacing in error message
- changed control flow to allow maxmem == ram_size in case slots == 0

 Hmm, right. Should I respin the series to fix it?
Send an extra incremental patch with subject:

I'd simply respin, especially a small series like this one.
