2020-02-17powerpc/hugetlb: Fix 512k hugepages on 8xx with 16k page sizeChristophe Leroy1-11/+18
Commit 55c8fc3f4930 ("powerpc/8xx: reintroduce 16K pages with HW assistance") redefined pte_t as a struct of 4 pte_basic_t, because in 16K pages mode there are four identical entries in the page table. But the size of hugepage tables is calculated based of the size of (void *). Therefore, we end up with page tables of size 1k instead of 4k for 512k pages. As 512k hugepage tables are the same size as standard page tables, ie 4k, use the standard page tables instead of PGT_CACHE tables.

2020-02-17powerpc/eeh: Fix deadlock handling dead PHBSam Bobroff1-10/+11
Recovering a dead PHB can currently cause a deadlock as the PCI rescan/remove lock is taken twice. This is caused as part of an existing bug in eeh_handle_special_event(). The pe is processed while traversing the PHBs even though the pe is unrelated to the loop. This causes the pe to be, incorrectly, processed more than once. Untangling this section can move the pe processing out of the loop and also outside the locked section, correcting both problems.

2020-02-15MIPS: cavium_octeon: Fix syncw generation.Mark Tomlinson1-1/+3
The Cavium Octeon CPU uses a special sync instruction for implementing wmb, and due to a CPU bug, the instruction must appear twice. A macro had been defined to hide this: #define __SYNC_rpt(type) (1 + (type == __SYNC_wmb)) which was intended to evaluate to 2 for __SYNC_wmb, and 1 for any other type of sync. However, this expression is evaluated by the assembler, and not the compiler, and the result of '==' in the assembler is 0 or -1, not 0 or 1 as it is in C. The net result was wmb() producing no code at all. The simple fix in this patch is to change the '+' to '-'.

2020-02-15mips: vdso: add build time check that no 'jalr t9' calls leftVictor Kamensky1-1/+7
vdso shared object cannot have GOT based PIC 'jalr t9' calls because nobody set GOT table in vdso. Contributing into vdso .o files are compiled in PIC mode and as result for internal static functions calls compiler will generate 'jalr t9' instructions. Those are supposed to be converted into PC relative 'bal' calls by linker when relocation are processed. Mips global GOT entries do have dynamic relocations and they will be caught by cmd_vdso_check Makefile rule. Static PIC calls go through mips local GOT entries that do not have dynamic relocations. For those 'jalr t9' calls could be present but without dynamic relocations and they need to be converted to 'bal' calls by linker. Add additional build time check to make sure that no 'jalr t9' slip through because of some toolchain misconfiguration that prevents 'jalr t9' to 'bal' conversion.

2020-02-15mips: vdso: fix 'jalr t9' crash in vdso codeVictor Kamensky1-0/+1
Observed that when kernel is built with Yocto mips64-poky-linux-gcc, and mips64-poky-linux-gnun32-gcc toolchain, resulting vdso contains 'jalr t9' instructions in its code and since in vdso case nobody sets GOT table code crashes when instruction reached. On other hand observed that when kernel is built mips-poky-linux-gcc toolchain, the same 'jalr t9' instruction are replaced with PC relative function calls using 'bal' instructions. The difference boils down to -mrelax-pic-calls and -mexplicit-relocs gcc options that gets different default values depending on gcc target triplets and corresponding binutils. -mrelax-pic-calls got enabled by default only in mips-poky-linux-gcc case. MIPS binutils ld relies on R_MIPS_JALR relocation to convert 'jalr t9' into 'bal' and such relocation is generated only if -mrelax-pic-calls option is on. Please note 'jalr t9' conversion to 'bal' can happen only to static functions. These static PIC calls use mips local GOT entries that are supposed to be filled with start of DSO value by run-time linker (missing in VDSO case) and they do not have dynamic relocations. Global mips GOT entries must have dynamic relocations and they should be prevented by cmd_vdso_check Makefile rule. Solution call out -mrelax-pic-calls and -mexplicit-relocs options explicitly while compiling MIPS vdso code. That would get correct and consistent between different toolchains behaviour.

2020-02-14context-tracking: Introduce CONFIG_HAVE_TIF_NOHZFrederic Weisbecker7-5/+17
A few archs (x86, arm, arm64) don't rely anymore on TIF_NOHZ to call into context tracking on user entry/exit but instead use static keys (or not) to optimize those calls. Ideally every arch should migrate to that behaviour in the long run. Settle a config option to let those archs remove their TIF_NOHZ definitions.

2020-02-14x86/entry: Remove _TIF_NOHZ from _TIF_WORK_SYSCALL_ENTRYThomas Gleixner1-6/+2
Evaluating _TIF_NOHZ to decide whether to use the slow syscall entry path is not only pointless, it's actually counterproductive: 1) Context tracking code is invoked unconditionally before that flag is evaluated. 2) If the flag is set the slow path is invoked for nothing due to #1 Remove it.

2020-02-14arm64: dts: allwinner: pinebook: Remove unused AXP803 regulatorsSamuel Holland1-15/+1
The Pinebook does not use the CSI bus on the A64. In fact it does not use GPIO port E for anything at all. Thus the following regulators are not used and do not need voltages set: - ALDO1: Connected to VCC-PE only - DLDO3: Not connected - ELDO3: Not connected Signed-off-by: Samuel Holland <samuel@sholland.org> Signed-off-by: Maxime Ripard <maxime@cerno.tech>

2020-02-14ARM: dts: sun7i: Add Linutronix Testbox v2 boardBastian Germann2-0/+48
The Testbox board is an open hardware enhancement for the Lamobo R1 router board. The Testbox board is used in the CI-RT project to manage devices under test (https://ci-rt.linutronix.de). The hardware project is located at https://github.com/ci-rt/testbox-shield The Testbox v2 expands the Lamobo R1 router board with - a power supply, - a CAN bus PHY, - a power control, - a relay, - an I2C EEPROM, - a secure key storage (ATECC608a) and - two RS232 compliant serial ports.
