2020-05-21arm64/cpufeature: Make doublelock a signed feature in ID_AA64DFR0Anshuman Khandual
Double lock feature can have the following possible values. 0b0000 - Double lock implemented 0b1111 - Double lock not implemented But in case of a conflict the safe value should be 0b1111. Hence this must be a signed feature instead. Also change FTR_EXACT to FTR_LOWER_SAFE. While here, fix the erroneous bit width value from 28 to 4.

ID_ISAR0[31..28] bits are RES0 in ARMv8, Reserved/UNK in ARMv7. Currently these bits get exposed through generic_id_ftr32[] which is not desirable.

2020-05-22powerpc/64s: Disable STRICT_KERNEL_RWXMichael Ellerman
Several strange crashes have been eventually traced back to STRICT_KERNEL_RWX and its interaction with code patching. Various paths in our ftrace, kprobes and other patching code need to be hardened against patching failures, otherwise we can end up running with partially/incorrectly patched ftrace paths, kprobes or jump labels, which can then cause strange crashes. Although fixes for those are in development, they're not -rc material. There also seem to be problems with the underlying strict RWX logic, which needs further debugging. So for now disable STRICT_KERNEL_RWX on 64-bit to prevent people from enabling the option and tripping over the bugs.

2020-05-21arm64: vdso: Fix CFI directives in sigreturn trampolineWill Deacon
Daniel reports that the .cfi_startproc is misplaced for the sigreturn trampoline, which causes LLVM's unwinder to misbehave: | I run into this with LLVM’s unwinder. | This combination was always broken. This prompted Dave to question our use of CFI directives more generally, and I ended up going down a rabbit hole trying to figure out how this very poorly documented stuff gets used. Move the CFI directives so that the "mysterious NOP" is included in the .cfi_{start,end}proc block and add a bunch of comments so that I can save myself another headache in future.

2020-05-21arm64: vdso: Don't prefix sigreturn trampoline with a BTI C instructionWill Deacon
For better or worse, GDB relies on the exact instruction sequence in the VDSO sigreturn trampoline in order to unwind from signals correctly. Commit c91db232da48 ("arm64: vdso: Convert to modern assembler annotations") unfortunately added a BTI C instruction to the start of __kernel_rt_sigreturn, which breaks this check. Thankfully, it's also not required, since the trampoline is called from a RET instruction when returning from the signal handler Remove the unnecessary BTI C instruction from __kernel_rt_sigreturn, and do the same for the 32-bit VDSO as well for good measure.

So with a series of changes from Suman Anna and Tero Kristo, let's configure IPUs and DSPs for dra7 devices like beagle-x15. And let's also configure the missing crypto accelerators for omap5 as those have been missing. Note that there are still some pending driver related patches to use IPU and DSP related features with mainline kernel, but those are independent of the devicetree changes.

2020-05-21mips: MAAR: Use more precise address maskSerge Semin
Indeed according to the MIPS32 Privileged Resource Architecgture the MAAR pair register address field either takes [12:31] bits for non-XPA systems and [12:55] otherwise. In any case the current address mask is just wrong for 64-bit and 32-bits XPA chips. So lets extend it to 59-bits of physical address value. This shall cover the 64-bits architecture and systems with XPA enabled, and won't cause any problem for non-XPA 32-bit systems, since address values exceeding the architecture specific MAAR mask will be just truncated with setting zeros in the unsupported upper bits.
