Syslinux - Feb 2011 - [PATCH][git-pull] MEMDISK: Process "mem=" parameter and apply to e820 ranges

git://git.zytor.com/users/genec/syslinux.git

Branch memdisk-maxmem-for-hpa

The goal of the changes was to process a "mem=" parameter (ie
"mem=128M" or "mem=134217728"; same value) and alter the
memory map
that MEMDISK returns in INT15h AXe820h by changing any type 1
(available) ranges above the "mem=" value to type 2 (reserved) and
splitting a type 1 that crosses this boundary if needed.  This reuses
code from com32/lib/ and copies suffix_number() from
com32/lib/syslinux/load_linux.c to com32/libutil/suffix_number.c.

This has shown useful for an end user when using a particular legacy
DOS application in a machine with 1024MiB or more of RAM.  Specifying
"mem=" without modifying MEMDISK was insufficient.

 I mentioned that some colleagues and friends would test this for you,
 just like to mention that we tested this on a Dell Poweredge 4600
 with 16GB of RAM, limited down to 1020MB and it did the business.

 I'd just like to take this opportunity to thank everyone on the list
 and IRC who helped me out.

 Cheers,
 Robert
