Add defconfig for Linux on Vybrid (vf610) on the secondary Cortex- M4 CPU. The use of a XIP image has been tested which needs to be loaded (e.g. using the custom m4boot loader) to the end of the available RAM at address 0x8f000000. The Cortex-M4 has a code-alias which makes sure that the instructions get fetched through the code bus (alias starts at 0x00800000 => 0x80800000 in system address). Hence, to get optimal performance, use 0x0f000000 as XIP_PHYS_ADDR. This address is additionally shifted by the length of the minimal loader which is inserted by m4boot. Currently, this offset is 0x80. The standard DRAM base address is configured to 0x8C000000, which gives the Cortex-M4 48MiB of RAM.

Commit ea08de16 ("ARM: dts: Add DISP1 power domain for exynos5420") added a device node for the Exynos5420 DISP1 power domain but dit not make the DP controller a consumer of that power domain. This causes an "Unhandled fault: imprecise external abort" error if the exynos-dp driver tries to access the DP controller registers and the PD was turned off. This lead to a kernel panic and a complete system hang. Make the DP controller device node a consumer of the DISP1 power domain to ensure that the PD is turned on when the exynos-dp driver is probed.

The following commit: f893959b ("x86/fpu: Don't abuse drop_init_fpu() in flush_thread()") removed drop_init_fpu() usage from flush_thread(). This seems to break things for me - the Go 1.4 test suite fails all over the place with floating point comparision errors (offending commit found through bisection). The functional change was that flush_thread() after this commit only calls restore_init_xstate() when both use_eager_fpu() and !used_math() are true. drop_init_fpu() (now fpu_reset_state()) calls restore_init_xstate() regardless of whether current used_math() - apply the same logic here. Switch used_math() -> tsk_used_math(tsk) to consistently use the grabbed tsk instead of current, like in the rest of flush_thread().

Commit 61f01dd9 ("x86_64, asm: Work around AMD SYSRET SS descriptor attribute issue") makes AMD processors set SS to __KERNEL_DS in __switch_to() to deal with cases when SS is NULL. This breaks Xen PV guests who do not want to load SS with__KERNEL_DS. Since the problem that the commit is trying to address would have to be fixed in the hypervisor (if it in fact exists under Xen) there is no reason to set X86_BUG_SYSRET_SS_ATTRS flag for PV VPCUs here. This can be easily achieved by adding x86_hyper_xen_hvm.set_cpu_features op which will clear this flag. (And since this structure is no longer HVM-specific we should do some renaming).

A spinlock is regarded as contended when there is at least one waiter. Currently, the code that checks whether there are any waiters rely on tail value being greater than head. However, this is not true if tail reaches the max value and wraps back to zero, so arch_spin_is_contended() incorrectly returns 0 (not contended) when tail is smaller than head. The original code (before regression) handled this case by casting the (tail - head) to an unsigned value. This change simply restores that behavior.

The L3 Error handling on OMAP5 for the most part is very similar to that of OMAP4, and had leveraged common data structures and register layout definitions so far. Upon closer inspection, there are a few minor differences causing an incorrect decoding and reporting of the master NIU upon an error: 1. The L3_TARG_STDERRLOG_MSTADDR.STDERRLOG_MSTADDR occupies 11 bits on OMAP5 as against 8 bits on OMAP4, with the master NIU connID encoded in the 6 MSBs of the STDERRLOG_MSTADDR field. 2. The CLK3 FlagMux component has 1 input source on OMAP4 and 3 input sources on OMAP5. The common DEBUGSS source is at a different input on each SoC. Fix the above issues by using a OMAP5-specific compatible property and using SoC-specific data where there are differences.
