This patch fixes a non-booting issue in Mainline. When booting with a compressed kernel, we need to be careful how we populate memory close to DDR start. AUTO_ZRELADDR is enabled by default in multi-arch enabled configurations, which place some restrictions on where the kernel is placed and where it will be uncompressed to on boot. AUTO_ZRELADDR takes the decompressor code's start address and masks out the bottom 28 bits to obtain an address to uncompress the kernel to (thus a load address of 0x42000000 means that the kernel will be uncompressed to 0x40000000 i.e. DDR START on this platform). Even changing the load address to after the co-processor's shared memory won't render a booting platform, since the AUTO_ZRELADDR algorithm still ensures the kernel is uncompressed into memory shared with the first co-processor (0x40000000). Another option would be to move loading to 0x4A000000, since this will mean the decompressor will decompress the kernel to 0x48000000. However, this would mean a large chunk (0x44000000 => 0x48000000 (64MB)) of memory would essentially be wasted for no good reason. Until we can work with ST to find a suitable memory location to relocate co-processor shared memory, let's disable the shared memory nodes. This will ensure a working platform in the mean time. NB: The more observant of you will notice that we're leaving the DMU shared memory node enabled; this is because a) it is the only one in active use at the time of this writing and b) it is not affected by the current default behaviour which is causing issues.

Based on the latest timing specifications for the TPS65218 from the data sheet, http://www.ti.com/lit/ds/symlink/tps65218.pdf, document SLDS206 from November 2014, we must change the i2c bus speed to better fit within the minimum high SCL time required for proper i2c transfer. When running at 400khz, measurements show that SCL spends 0.8125 uS/1.666 uS high/low which violates the requirement for minimum high period of SCL provided in datasheet Table 7.6 which is 1 uS. Switching to 100khz gives us 5 uS/5 uS high/low which both fall above the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low. Without this patch occasionally a voltage set operation from the kernel will appear to have worked but the actual voltage reflected on the PMIC will not have updated, causing problems especially with cpufreq that may update to a higher OPP without actually raising the voltage on DCDC2, leading to a hang.

A few platforms are currently missing clocksource_probe() completely in their time_init functionality. On OMAP3430 for example, this is causing cpuidle to be pretty much dead, as the counter32k is not going to be registered and instead a gptimer is used as a clocksource. This will tick in periodic mode, preventing any deeper idle states. While here, also drop one unnecessary check for populated DT before existing clocksource_probe() call. Signed-off-by:

In the omap gpmc driver it can be noticed that GPMC_CONFIG4_OEEXTRADELAY is overwritten by the WEEXTRADELAY value from the device tree and GPMC_CONFIG4_WEEXTRADELAY is not updated by the value from the device tree. As a consequence, the memory accesses cannot be configured properly when the extra delay are needed for OE and WE. Fix the update of GPMC_CONFIG4_WEEXTRADELAY with the value from the device tree file and prevents GPMC_CONFIG4_OEXTRADELAY being overwritten by the WEXTRADELAY value from the device tree.

Further testing with false negatives suppressed by commit 293e2421 ("rcu: Remove superfluous versions of rcu_read_lock_sched_held()") identified another unprotected use of RCU from the idle loop.

This prevents stacking filesystems (ecryptfs and overlayfs) from using procfs as lower filesystem. There is too much magic going on inside procfs, and there is no good reason to stack stuff on top of procfs. (For example, procfs does access checks in VFS open handlers, and ecryptfs by design calls open handlers from a kernel thread that doesn't drop privileges or so.) Signed-off-by:
