devm_kfree should not have to be explicitly used. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,d; @@ x = devm_kzalloc(...) ... ?-devm_kfree(d,x); // </smpl> Signed-off-by:

This driver was for the ProGear webpad device which was produced in 2000/2001 and is not available on a market. I no longer have this hardware so can not even check how Linux works on it. Signed-off-by:

If you're going to have a conditional branch after each 32x32->64-bit multiply, might as well shrink the code and make it a loop. This also avoids using the long multiply for small integers. (This leaves the comments in a confusing state, but that's a separate patch to make review easier.) Signed-off-by:

orderly_poweroff is trying to poweroff platform in two steps: step 1: Call user space application to poweroff step 2: If user space poweroff fail, then do a force power off if force param is set. The bug here is, step 1 is always successful with param UMH_NO_WAIT, which obey the design goal of orderly_poweroff. We have two choices here: UMH_WAIT_EXEC which means wait for the exec, but not the process; UMH_WAIT_PROC which means wait for the process to complete. we need to trade off the two choices: If using UMH_WAIT_EXEC, there is potential issue comments by Serge E. Hallyn: The exec will have started, but may for whatever (very unlikely) reason fail. If using UMH_WAIT_PROC, there is potential issue comments by Eric W. Biederman: If the caller is not running in a kernel thread then we can easily get into a case where the user space caller will block waiting for us when we are waiting for the user space caller. Thanks for their excellent ideas, based on the above discussion, we finally choose UMH_WAIT_EXEC, which is much more safe, if the user application really fails, we just complain the application itself, it seems a better choice here.

As kernel_power_off() calls disable_nonboot_cpus(), we may also want to have kernel_restart() call disable_nonboot_cpus(). Doing so can help machines that require boot cpu be the last alive cpu during reboot to survive with kernel restart. This fixes one reboot issue seen on imx6q (Cortex-A9 Quad). The machine requires that the restart routine be run on the primary cpu rather than secondary ones. Otherwise, the secondary core running the restart routine will fail to come to online after reboot.

Historically, the top three bytes of personality have been used for things such as ADDR_NO_RANDOMIZE, which made sense only for specific architectures. We now however have a flag there that is general no matter the architecture (UNAME26); generally we have to be careful to preserve the personality flags across exec(). This patch fixes tile architecture not to forcefully overwrite personality flags during exec(). In addition to that, we fix two other things along the way: - exec_domain switching is fixed -- set_personality() should always be used instead of directly assigning to current->personality. - as pointed out by Arnd Bergmann, PER_LINUX_32BIT is not used anywhere by tile, so let's just drop that in favor of PER_LINUX Signed-off-by:

We now however have a flag there that is general no matter the architecture (UNAME26); generally we have to be careful to preserve the personality flags across exec(). This patch tries to fix all architectures that forcefully overwrite personality flags during exec() (ppc32 and s390 have been fixed recently by commits f9783ec8 ("[S390] Do not clobber personality flags on exec") and 59e4c3a2 ("powerpc/32: Don't clobber personality flags on exec") in a similar way already).

Fix the const sections for the code generated by crc32 table. There's no ro version of the cacheline aligned section, so we cannot put in const data without a conflict Just don't make the crc tables const for now.
