Commit 6afe1a1f ("PM: Remove legacy PM") removed the initialization of retval, causing: arch/frv/kernel/pm.c: In function 'sysctl_pm_do_suspend': arch/frv/kernel/pm.c:165:5: warning: 'retval' may be used uninitialized in this function [-Wuninitialized] Remove the variable completely to fix this, and convert to a proper switch (...) { ... } construct to improve readability.

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.

The PA-RISC tool chain seems to have some problem with correct read/write attributes on sections. This causes problems when the const sections are fixed up for other architecture to only contain truly read-only data. Disable const sections for PA-RISC This can cause a bit of noise with modpost.

The ACARD driver calls udelay() with a value > 2000, which leads to to the following compilation error on ARM: ERROR: "__bad_udelay" [drivers/scsi/atp870u.ko] undefined! make[1]: *** [__modpost] Error 1 This is because udelay is defined on ARM, roughly speaking, as #define udelay(n) ((n) > 2000 ? __bad_udelay() : \ __const_udelay((n) * ((2199023U*HZ)>>11))) The argument to __const_udelay is the number of jiffies to wait divided by 4, but this does not work unless the multiplication does not overflow, and that is what the build error is designed to prevent. The intended behavior can be achieved by using mdelay to call udelay multiple times in a loop. [jrnieder@gmail.com: adding context] Signed-off-by:

The call if_changed mechanism does not work when the command contains backslashes. This basically is an issue with lzo and bzip2 compressed kernels. The compressed binaries do not contain the uncompressed image size, so these use size_append to append the size. This results in backslashes in the executed command. With this if_changed always detects a change in the command and rebuilds the compressed image even if nothing has changed. Fix this by escaping backslashes in make-cmd Signed-off-by:

It seems the current (gcc 4.6.3) no longer provides this so make it conditional. As reported by Tony before, the mn10300 architecture cross-compiles with gcc-4.6.3 if -mmem-funcs is not added to KBUILD_CFLAGS. Reported-by:

Fengguang correctly points out that the firmware reading should not use vfs_read(), since the buffer is in kernel space. The vfs_read() just happened to work for kernel threads, but sparse warns about the incorrect address spaces, and it's definitely incorrect and could fail for other users of the firmware loading.

Pull remoteproc update from Ohad Ben-Cohen: - Remoteproc Recovery - by Fernando Guzman Lugo When a remote processor crash is detected, this mechanism will remove all virtio children devices, wait until their drivers let go, hard reset the remote processor and reload the firmware (resulting in the relevant virtio children devices re-added). Essentially the entire software stack is reset, together with the relevant hardware, so users don't have to reset the entire phone. - STE Modem driver is added - by Sjur Brændeland - OMAP DSP boot address support is added - by Juan Gutierrez - A handful of fixes/cleanups - Sjur Brændeland, Dan Carpenter, Emil Goode * tag 'remoteproc-for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc: remoteproc: Fix use of format specifyer remoteproc: fix a potential NULL-dereference on cleanup remoteproc: select VIRTIO to avoid build breakage remoteproc: return -EFAULT on copy_from_user failure remoteproc: snprintf() can return more than was printed remoteproc: Add STE modem driver remtoteproc: maintain max notifyid remoteproc: create a 'recovery' debugfs entry remoteproc: add actual recovery implementation remoteproc: add rproc_report_crash function to notify rproc crashes remoteproc: Add dependency to HAS_DMA remoteproc/omap: set bootaddr support
