Add call to early_memtest() so that kernel compiled with CONFIG_MEMTEST really perform memtest at startup when requested via 'memtest' boot parameter. Tested-by: Daniel Axtens <dja@xxxxxxxxxx> Signed-off-by: Christophe Leroy <christophe.leroy@xxxxxx> --- v3: updated kernel parameters documentation to mention PPC v2: moved the test after initmem_init() as PPC64 sets max_low_pfn later than PPC32.
