Subject: libxc: increase lzma max memory constant to 128Mby
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=a14b0eb5844cda6752aa98ab5509e565b92b17d4;p=people%2Fliuw%2Flibxenctrl-split%2Fxen.git

libxc: increase lzma max memory constant to 128Mby

According to lzma's configure.ac (!) the minimum memory limit to cope
with arbitrary input is 128Mby (!)

This is obviously an unreasonable amount of memory for this kind of
task, but we need to increase the constant limit for it not to
randomly fail.  So do so.
