When we call tzic_enable_wake function, the kernel will crash because of access to an unmapped address. This is because two register access operations forgot to add base address. Signed-off-by:

The mx3fb driver needs the clock the IPU runs in order to calculate the divider for the LCD clock. This patch adds the clock rate calculation routine for the i.MX35 CPU. Signed-off-by:

According to the Datasheet: "i.MX35 (MCIMX35) Multimedia Applications Processor Reference Manual, Rev. 2" "Table 14-6. PDR0 Field Descriptions" the divider is CCM_PER_AHB[3:0] + 1. This patch adds the missing + 1. Signed-off-by:

In the v2 reference manual there are no dividers combined of two dividers. Instead, all dividers are simple 6bit dividers. I assume the combined dividers only exist in preliminary hardware. Signed-off-by:

If a watchdog reset occurs after booting in internal boot mode, the i.MX35 won't boot anymore. The boot ROM code seems to assume that some clocks are turned on (they are after a power-on reset). This patch turns on the necessary clocks. Signed-off-by:

With this change, the arch/tile Makefile will only check for a valid combination of CROSS_COMPILE vs "uname -m" for a few common targets that are typically the ones we get wrong (vmlinux, all, and modules). The change handles the case of an empty "make" goal like "make all". Signed-off-by:

This commit makes the stack guard page somewhat less visible to user space. It does this by: - not showing the guard page in /proc/<pid>/maps It looks like lvm-tools will actually read /proc/self/maps to figure out where all its mappings are, and effectively do a specialized "mlockall()" in user space. By not showing the guard page as part of the mapping (by just adding PAGE_SIZE to the start for grows-up pages), lvm-tools ends up not being aware of it. - by also teaching the _real_ mlock() functionality not to try to lock the guard page. That would just expand the mapping down to create a new guard page, so there really is no point in trying to lock it in place. It would perhaps be nice to show the guard page specially in /proc/<pid>/maps (or at least mark grow-down segments some way), but let's not open ourselves up to more breakage by user space from programs that depends on the exact deails of the 'maps' file. Special thanks to Henrique de Moraes Holschuh for diving into lvm-tools source code to see what was going on with the whole new warning.
