The timeout value is in jiffies, so it should be using HZ, not a plain number. As '10000' is ambiguous, 1HZ is used as conservative default. Signed-off-by: NWolfram Sang <w.sang@pengutronix.de> Cc: Valentin Yakovenkov <yakovenkov@gmail.com> Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Architectures that handle DMA-non-coherent memory need to set ARCH_KMALLOC_MINALIGN to make sure that kmalloc'ed buffer is DMA-safe: the buffer doesn't share a cache with the others.

Add a little strncpy optimization which can easily cut boot time by 20%. When the kernel is booting with initramfs, it builds up the filesystem from a cpio archive by calling strncpy_from_user() via fs/namei.c's do_getname() on every file in the archive (which can be lots) with a length of PATH_MAX (1024). This causes the dest of the strncpy to be padded with many NUL bytes. This optimization mostly causes these NUL bytes to be padded with a call to memset() which is already optimized for filling memory quickly, but the hardware loop helps a little bit as well. Boot time measured with 'loglevel=0' so UART speed doesn't get in the way. Signed-off-by: NRobin Getz <robin.getz@analog.com> Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The IADDR2DTEST() macro had some duplicated logic with bit 11 and some incorrect comments, so scrub all of that. In order to verify these aren't a problem (and won't be in the future), extend the self tests to operate on as much L1 SRAM as possible. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Since 'extern inline' doesn't work correctly in the context of the Linux kernel (too many overriding defines), move the string functions to normal lib/ assembly files (like the existing mem funcs). This avoids the forced inline all over the kernel and allows us to place them constantly in L1. This also avoids some module failures when gcc inserts calls to string functions but the kernel build system doesn't fully consult the library archives.

Tweak the for loops that operate on the SIC IAR system MMRs to avoid re-reading them multiple times in a row. System MMRs are a little slower to access, so avoid the penalty when possible. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

While the CC pseudo register can be deduced from the ASTAT register, make sure we set its value correctly instead of always stubbing it out as 0. GDB itself looks at this pseudo register instead of ASTAT, so we have to supply the right value. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

NMIs are not safe to return from because many anomaly workarounds are implemented by disabling interrupts. The NMI obviously violates this assumption. Since the NMI watchdog never returns, we don't have to worry about it clobbering RETN when it is being used as a scratch register with the exception stack.

A few pseudo debug insns exist to make testing of simulators easier. Since these don't actually exist in the hardware, we have to have the exception handler take care of emulating these. This allows sim test cases to be executed unmodified under Linux and thus simplify debugging greatly.

Now that the split traps code has moved all the verbose output to the trace.c file, we can unify all the CONFIG_DEBUG_VERBOSE handling. This gets rid of much of the crappy ifdef forest and enables usage of normal pr_xxx functions so checkpatch stops complaining.

The current kernel/traps.c file has grown a bit unwieldy as more debugging functionality has been added over time, so split it up into more logical files. There should be no functional changes here, just minor whitespace tweaking. This should make future extensions easier to manage.

This patch removes a custom GPIO wakeup API which allowed GPIOs to act as wakeup sources, which are not configured as Interrupts. This API is a leftover from the time before irq_wake was established. From now on people must use enable_irq_wake(GPIO_IRQx) and the GPIO in question needs to be configured as Interrupt.
