Add support for AT_L1I_CACHESIZE, AT_L1I_CACHEGEOMETRY,
AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY, AT_L2_CACHESIZE,
AT_L2_CACHEGEOMETRY, AT_L3_CACHESIZE and AT_L3_CACHEGEOMETRY when
LD_SHOW_AUXV=1.
AT_L*_CACHESIZE is printed as decimal and represent the number of
bytes of the cache.
AT_L*_CACHEGEOMETRY is treated in order to specify the cache line size
and its associativity.
Example output from a POWER8:
AT_L1I_CACHESIZE: 32768
AT_L1I_CACHEGEOMETRY: 128B line size, 8-way set associative
AT_L1D_CACHESIZE: 65536
AT_L1D_CACHEGEOMETRY: 128B line size, 8-way set associative
AT_L2_CACHESIZE: 524288
AT_L2_CACHEGEOMETRY: 128B line size, 8-way set associative
AT_L3_CACHESIZE: 8388608
AT_L3_CACHEGEOMETRY: 128B line size, 8-way set associative
Some of the new types are longer than the previous ones, requiring to
increase the indentation in order to keep the values aligned.
* elf/dl-sysdep.c (auxvars): Add AT_L1I_CACHESIZE,
AT_L1I_CACHEGEOMETRY, AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY,
AT_L2_CACHESIZE, AT_L2_CACHEGEOMETRY, AT_L3_CACHESIZE and
AT_L3_CACHEGEOMETRY. Fix indentation when printing the other
fields.
(_dl_show_auxv): Give a special treatment to
AT_L1I_CACHEGEOMETRY, AT_L1D_CACHEGEOMETRY, AT_L2_CACHEGEOMETRY
and AT_L3_CACHEGEOMETRY.
* sysdeps/powerpc/dl-procinfo.h (cache_geometry): New function.
(_dl_procinfo): Fix indentation when printing AT_HWCAP and
AT_HWCAP2. Add support for AT_L1I_CACHEGEOMETRY,
AT_L1D_CACHEGEOMETRY, AT_L2_CACHEGEOMETRY and AT_L3_CACHEGEOMETRY.
