Subject: powerpc/mce: Reduce the size of event arrays
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=17c5cf0fb993e219bda4f53aa9ec90d3cfcf92ab;p=linux.git

powerpc/mce: Reduce the size of event arrays

Maximum recursive depth of MCE is 4, Considering the maximum depth
allowed reduce the size of event to 10 from 100. This saves us ~19kB
of memory and has no fatal consequences.
