Greer" To: Paul Mackerras Subject: [POWERPC] 32-bit early_init() should zero from __bss_start to __bss_stop only Message-ID: <20061025233649.GB17461@mag.az.mvista.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: linuxppc-dev List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Currently, early_init() in setup_32.c zeroes from '_bss_start' to '_end'. It should only zero from '__bss_start' to '__bss_stop'. This patch does that. Signed-off-by: Mark A.
