According to Russell King handle_edge_irq is only useful for "edge-based inputs where the controller does not remember transitions with the input masked." So using handle_edge_irq unconditionally for both edge and level irqs is wrong. Testing showed that the controller does remember transitions while the interrupt is masked. So use handle_level_irq unconditionally.

We get rid of CTS/RTS lines on uart0 on our platform. This is the port we use as main kernel console. We do not want it to be blocking because of CTS/RTS signals, not allowing the system to boot or print messages. However we often use it with a bluetooth module needing CTS/RTS lines as backup login in case of trouble. To be able to use it, we assert CTS low so that the module can always send chars.

Mapping the same memory using two different attributes (memory type, shareability, cacheability) is unpredictable. During boot, we encounter a situation when we're updating the kernel's page tables which can lead to dirty cache lines existing in the cache which are subsequently missed. This causes stack corruption, and therefore a crash. Therefore, ensure that the shared and cacheability settings matches the configuration that will be used later; this together with the restriction in early_cachepolicy() ensures that we won't create a mismatch during boot.

When SPARSEMEM_EXTREME is enabled, memory_present() wants to use bootmem to allocate data structures. However, we call memory_present() after declaring memory to bootmem, but before we've reserved areas. This leads to sparsemem data structures being overwritten later in the kernel's initialization (when slab initializes.) Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

The signal restarting code was placed on the user stack when OABI compatibility is enabled. Unfortunately, with an EABI NX executable, this results in an attempt to run code from the non-executable stack, which segfaults the application. Fix this by placing the code in the vectors page, along side the signal return code, and directing the application to that code.
