Subject: checkstack.pl: fix for aarch64
X-Git-Tag: v4.20-rc7~1^2~1
X-Git-Url: http://git.samba.org/samba.git/?p=sfrench%2Fcifs-2.6.git;a=commitdiff_plain;h=f1733a1d3cd32a9492f4cf866be37bb46e10163d;hp=f1733a1d3cd32a9492f4cf866be37bb46e10163d

checkstack.pl: fix for aarch64

There is actually a space after "sp," like this,

    ffff2000080813c8:       a9bb7bfd        stp     x29, x30, [sp, #-80]!

Right now, checkstack.pl isn't able to print anything on aarch64,
because it won't be able to match the stating objdump line of a function
due to this missing space.  Hence, it displays every stack as zero-size.

After this patch, checkpatch.pl is able to match the start of a
function's objdump, and is then able to calculate each function's stack
correctly.
