Subject: [PATCH 1/2] powerpc/xmon: Specify the full format in DUMP() macro
Date: Wed, 23 May 2018 21:48:36 +1000	[thread overview]
Message-ID: <20180523114837.6980-1-mpe@ellerman.id.au> (raw)

In dump_one_paca() the DUMP macro unconditionally prepends '#' to the
printf format specifier. In most cases we're using either 'x' or 'lx'
etc. and that is OK. But for 'p' and other formats using '#' is
actually undefined, and once we enable printf() checking for
xmon_printf() we will get warnings from the compiler.

So just have each usage specify the full format, that way we can omit
'#' when it's inappropriate.
