* parisc: Prevent panic at system haltHelge Deller2018-04-111-8/+5
| | | | | | | | | | | | | | | | | | | | | When issuing a "shutdown -h now", the reboot syscall calls kernel_halt() which shouldn't return, otherwise one gets this panic: reboot: System halted Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000000 CPU: 0 PID: 1 Comm: systemd-shutdow Not tainted 4.16.0-32bit+ #560 Backtrace: [<1018a694>] show_stack+0x18/0x28 [<106e68a8>] dump_stack+0x80/0x10c [<101a4df8>] panic+0xfc/0x290 [<101a90b8>] do_exit+0x73c/0x914 [<101c7e38>] SyS_reboot+0x190/0x1d4 [<1017e444>] syscall_exit+0x0/0x14 Fix it by letting machine_halt() call machine_power_off() which doesn't return.

* parisc: Switch to generic COMPAT_BINFMT_ELFHelge Deller2018-04-114-132/+42
| | | | | | | | | | | | | | | Drop our own compat binfmt implementation in arch/parisc/kernel/binfmt_elf32.c in favour of the generic implementation with CONFIG_COMPAT_BINFMT_ELF. While cleaning up the dependencies, I noticed that ELF_PLATFORM was strangely defined: On a 32-bit kernel, it was defined to "PARISC", while when running in compat mode on a 64-bit kernel it was defined to "PARISC32". Since it doesn't seem to be used in glibc yet, it's now defined in both cases to "PARISC". In any case, it can be distinguished because it's either a 32-bit or a 64-bit ELF file.

| * c6x: pass endianness info to sparseLuc Van Oostenryck2018-04-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | c6x depends on the macro '_BIG_ENDIAN' being defined or not to correctly select or define endian-specific macros, structures or pieces of code. This macro is predefined by the compiler but sparse knows nothing about it and thus may pre-process files differently from what gcc would. Fix this by passing '-D_BIG_ENDIAN' when compiling a big-endian kernel, like GCC would have done.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Luxul devices use PCIe connected GPIO LEDs that are not available until the PCI subsytem and its drivers load. Using the same array for these LEDs would block registering any LEDs until all GPIOs become available. This may be undesired behavior as some LEDs should be available as early as possible (e.g. system status LED). This patch will allow registering available LEDs while deferring these PCIe GPIO connected 'extra' LEDs until they become available.

Of course PHYSICAL_START itself is a misnomer as the load address is virtual rather than physical (or otherwise sign-extension would not apply).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to fetch the correct entry point with the ISA bit included, for use by non-ELF boot loaders, parse the output of `objdump -f' for the start address recorded in the kernel executable itself, rather than using `nm' to get the value of the `kernel_entry' symbol. Sign-extend the address retrieved if 32-bit, so that execution is correctly started on 64-bit processors as well. The tool always prints the entry point using either 8 or 16 hexadecimal digits, matching the address width (aka class) of the ELF file, even in the presence of leading zeros. Signed-off-by: Maciej W.

While set, attempting to send a power-down command to a core will be blocked, and the CPC will instead send the core to clock-off state. This can interfere with systems fully entering a low power state where all cores, CM, GIC, etc are powered down. Detect that a JTAG probe is / has been connected to the cluster and block the suspend attempt. Attempting to suspend the system while a JTAG probe is connected now yields: # echo mem > /sys/power/state [ 11.654000] PM: Syncing filesystems ... done. [ 11.658000] JTAG probe is connected - abort suspend -sh: echo: write error: Operation not permitted # To restore suspend, the JTAG probe should be disconnected or put into quiescent state.

| * | MIPS: Introduce isa-rev.h to define MIPS_ISA_REVMatt Redfearn2018-03-091-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are multiple instances in the kernel where we need to include or exclude particular instructions based on the ISA revision of the target processor. For MIPS32 / MIPS64, the compiler exports a __mips_isa_rev define. However, when targeting MIPS I - V, this define is absent. This leads to each use of __mips_isa_rev having to check that it is defined first. To simplify this, introduce the isa-rev.h header which always exports MIPS_ISA_REV. The name is changed so as to avoid confusion with the compiler builtin and to avoid accidentally using the builtin. MIPS_ISA_REV is defined to the compilers builtin if provided, or 0, which satisfies all current usages.

We have many platforms which avoid this loop by implementing their own, many using some variation upon executing a wait instruction to lower CPU power usage if we reach this point. In order to prepare for cleaning up these various custom implementations of the same thing, this patch makes the generic machine_halt(), machine_power_off() & machine_restart() functions each make use of the wait instruction to lower CPU power usage in cases where we know that the wait instruction is available. If wait isn't known to be supported then we fall back to calling cpu_wait(), and if we don't have a cpu_wait() callback then we effectively continue using a busy loop. In effect the new machine_hang() function provides a superset of the functionality that the various platforms currently provide differing subsets of.

Half of the branch up to commit d2c997c0f145 ("fs, dax: use page->mapping to warn...") have been in -next for several releases. The of_pmem driver and the address range scrub rework were late arrivals, and the dax work was scaled back at the last moment. The of_pmem driver missed a previous merge window due to an oversight. A sense of obligation to rectify that miss is why it is included for 4.17. It has acks from PowerPC folks. Stephen reported a build failure that only occurs when merging it with your latest tree, for now I have fixed that up by disabling modular builds of of_pmem. A test merge with your tree has received a build success report from the 0day robot over 156 configs. An initial version of the ARS rework was submitted before the merge window. It is self contained to libnvdimm, a net code reduction, and passing all unit tests. The filesystem-dax changes are based on the wait_var_event() functionality from tip/sched/core. However, late review feedback showed that those changes regressed truncate performance to a large degree. The branch was rewound to drop the truncate behavior change and now only includes preparation patches and cleanups (with full acks and reviews). The finalization of this dax-dma-vs-trnucate work will need to wait for 4.18. Summary: - A rework of the filesytem-dax implementation provides for detection of unmap operations (truncate / hole punch) colliding with in-progress device-DMA. A fix for these collisions remains a work-in-progress pending resolution of truncate latency and starvation regressions. - The of_pmem driver expands the users of libnvdimm outside of x86 and ACPI to describe an implementation of persistent memory on PowerPC with Open Firmware / Device tree. - Address Range Scrub (ARS) handling is completely rewritten to account for the fact that ARS may run for 100s of seconds and there is no platform defined way to cancel it. ARS will now no longer block namespace initialization. - The NVDIMM Namespace Label implementation is updated to handle label areas as small as 1K, down from 128K. - Miscellaneous cleanups and updates to unit test infrastructure" * tag 'libnvdimm-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (39 commits) libnvdimm, of_pmem: workaround OF_NUMA=n build error nfit, address-range-scrub: add module option to skip initial ars nfit, address-range-scrub: rework and simplify ARS state machine nfit, address-range-scrub: determine one platform max_ars value powerpc/powernv: Create platform devs for nvdimm buses doc/devicetree: Persistent memory region bindings libnvdimm: Add device-tree based driver libnvdimm: Add of_node to region and bus descriptors libnvdimm, region: quiet region probe libnvdimm, namespace: use a safe lookup for dimm device name libnvdimm, dimm: fix dpa reservation vs uninitialized label area libnvdimm, testing: update the default smart ctrl_temperature libnvdimm, testing: Add emulation for smart injection commands nfit, address-range-scrub: introduce nfit_spa->ars_state libnvdimm: add an api to cast a 'struct nd_region' to its 'struct device' nfit, address-range-scrub: fix scrub in-progress reporting dax, dm: allow device-mapper to operate without dax support dax: introduce CONFIG_DAX_DRIVER fs, dax: use page->mapping to warn if truncate collides with a busy page ext2, dax: introduce ext2_dax_aops ...

Changing TBI PHY address therefore does not work on LS1021A. The real (and documented) address of the TBIPA registere lies in the eTSEC block and not in MDIO/MII, which is read/write, so using that fixes the problem.
