From ea4407834118405ef419e9b07794ceacadc01bae Mon Sep 17 00:00:00 2001 From: NISHIMOTO Hiroki Date: Fri, 15 Jan 2010 08:25:00 +0900 Subject: sh: mach-ecovec24: Add motion sensor driver support. This patch adds support for the lis3lv02d motion sensor connected via i2c on the Ecovec board. Tested with evtest.

As there are binaries that use both socketcall has to stay around. The current ABI prefers direct syscalls. It was pointed out that when sys_recvmmsg was added in, sys_accept4 was overlooked. This takes care of wiring it up.

It doesn't just flush the old executable environment, it also starts up the new one. Which is very inconvenient for things like setting up the new personality, because we want the new personality to affect the starting of the new environment, but at the same time we do _not_ want the new personality to take effect if flushing the old one fails. As a result, the x86-64 '32-bit' personality is actually done using this insane "I'm going to change the ABI, but I haven't done it yet" bit (TIF_ABI_PENDING), with SET_PERSONALITY() not actually setting the personality, but just the "pending" bit, so that "flush_thread()" can do the actual personality magic. This patch in no way changes any of that insanity, but it does split the 'flush_old_exec()' function up into a preparatory part that can fail (still called flush_old_exec()), and a new part that will actually set up the new exec environment (setup_new_exec()). All callers are changed to trivially comply with the new world order. Signed-off-by: H.
