Subject: [PATCH 3/5] powerpc, offset: Change PACA_DSCR to PACA_DSCR_DEFAULT
Date: Mon, 8 Dec 2014 12:00:10 +0530 [thread overview]
Message-ID: <1418020212-4303-3-git-send-email-khandual@linux.vnet.ibm.com> (raw)
In-Reply-To: <1418020212-4303-1-git-send-email-khandual@linux.vnet.ibm.com>
PACA_DSCR offset macro tracks dscr_default element in the paca
structure. Better change the name of this macro to match that
of the data element it tracks. Makes the code more readable.
