docs: process/4.Coding.rst: Fix a couple of document refs In Documentation/process/4.Coding.rst there were a couple of paragraphs that spilled over the 80 character line length. This was likely caused when the document was converted to reStructuredText. Re-flow the paragraphs and make the document references proper reStructuredText :ref: links. This also adds the appropriate reStructuredText file heading to kernel-parameters.rst as referenced by the kernel-parameters link in this patch.

docs: Clean up and organize the admin guide a bit The admin guide is a good start, but it's time to turn it into something better than an unordered blob of files. This is a first step in that direction. The TOC has been split up and annotated, the guides have been reordered, and minor tweaks have been applied to a few of them. One consequence of splitting up the TOC is that we don't really want to use :numbered: anymore, since the count resets every time and there doesn't seem to be a way to change that. Eventually we probably want to group the documents into sub-books, at which point we can go back to a single TOC, but it's probably early to do that.

lib/bitmap.c: enhance bitmap syntax Today there are platforms with many CPUs (up to 4K). Trying to boot only part of the CPUs may result in too long string. For example lets take NPS platform that is part of arch/arc. This platform have SMP system with 256 cores each with 16 HW threads (SMT machine) where HW thread appears as CPU to the kernel. In this example there is total of 4K CPUs. When one tries to boot only part of the HW threads from each core the string representing the map may be long... For example if for sake of performance we decided to boot only first half of HW threads of each core the map will look like: 0-7,16-23,32-39,...,4080-4087 This patch introduce new syntax to accommodate with such use case. I added an optional postfix to a range of CPUs which will choose according to given modulo the desired range of reminders i.e.: <cpus range>:sed_size/group_size For example, above map can be described in new syntax like this: 0-4095:8/16 Note that this patch is backward compatible with current syntax.

lib: bitmap: support "N" as an alias for size of bitmap While this is done for all bitmaps, the original use case in mind was for CPU masks and cpulist_parse() as described below. It seems that a common configuration is to use the 1st couple cores for housekeeping tasks. This tends to leave the remaining ones to form a pool of similarly configured cores to take on the real workload of interest to the user. So on machine A - with 32 cores, it could be 0-3 for "system" and then 4-31 being used in boot args like nohz_full=, or rcu_nocbs= as part of setting up the worker pool of CPUs. But then newer machine B is added, and it has 48 cores, and so while the 0-3 part remains unchanged, the pool setup cpu list becomes 4-47. Multiple deployment becomes easier when we can just simply replace 31 and 47 with "N" and let the system substitute in the actual number at boot; a number that it knows better than we do.

bitmap_parse: Support 'all' semantics RCU code supports an 'all' group as a special case when parsing rcu_nocbs parameter. This patch moves the 'all' support to the core bitmap_parse code, so that all bitmap users can enjoy this extension. Moving 'all' parsing to a bitmap_parse level also allows users to pass patterns together with 'all' in regular group:pattern format, for example, "rcu_nocbs=all:1/2" would offload all the even-numbered CPUs regardless of the number of CPUs on the system.

doc: Add EARLY flag to early-parsed kernel boot parameters Kernel boot parameters declared with early_param() are parsed before embedded parameters are extracted from initrd, and early_param() parameters are not helpful when embedded in initrd. Therefore, mark early_param() kernel boot parameters with "EARLY" in kernel-parameters.txt. The following early_param() calls declare kernel boot parameters that are undocumented: early_param("atmel.pm_modes", at91_pm_modes_select); early_param("mem_fclk_21285", early_fclk); early_param("ecc", early_ecc); early_param("cachepolicy", early_cachepolicy); early_param("nodebugmon", early_debug_disable); early_param("kfence.sample_interval", parse_kfence_early_init); early_param("additional_cpus", setup_additional_cpus); early_param("stram_pool", atari_stram_setup); early_param("disable_octeon_edac", disable_octeon_edac); early_param("rd_start", rd_start_early); early_param("rd_size", rd_size_early); early_param("coherentio", setcoherentio); early_param("nocoherentio", setnocoherentio); early_param("fadump", early_fadump_param); early_param("fadump_reserve_mem", early_fadump_reserve_mem); early_param("no_stf_barrier", handle_no_stf_barrier); early_param("no_rfi_flush", handle_no_rfi_flush); early_param("smt-enabled", early_smt_enabled); early_param("ppc_pci_reset_phbs", pci_reset_phbs_setup); early_param("ps3fb", early_parse_ps3fb); early_param("ps3flash", early_parse_ps3flash); early_param("novx", disable_vector_extension); early_param("nobp", nobp_setup_early); early_param("nospec", nospec_setup_early); early_param("possible_cpus", _setup_possible_cpus); early_param("stp", early_parse_stp); early_param("nopfault", nopfault); early_param("nmi_mode", nmi_mode_setup); early_param("sh_mv", early_parse_mv); early_param("pmb", early_pmb); early_param("hvirq", early_hvirq_major); early_param("cfi", cfi_parse_cmdline); early_param("disableapic", setup_disableapic); early_param("noapictimer", parse_disable_apic_timer); early_param("disable_cpu_apicid", apic_set_disabled_cpu_apicid); early_param("uv_memblksize", parse_mem_block_size); early_param("retbleed", retbleed_parse_cmdline); early_param("no-kvmclock-vsyscall", parse_no_kvmclock_vsyscall); early_param("update_mptable", update_mptable_setup); early_param("alloc_mptable", parse_alloc_mptable_opt); early_param("possible_cpus", _setup_possible_cpus); early_param("lsmsi", early_parse_ls_scfg_msi); early_param("nokgdbroundup", opt_nokgdbroundup); early_param("kgdbcon", opt_kgdb_con); early_param("kasan", early_kasan_flag); early_param("kasan.mode", early_kasan_mode); early_param("kasan.vmalloc", early_kasan_flag_vmalloc); early_param("kasan.page_alloc.sample", early_kasan_flag_page_alloc_sample); early_param("kasan.page_alloc.sample.order", early_kasan_flag_page_alloc_sample_order); early_param("kasan.fault", early_kasan_fault); early_param("kasan.stacktrace", early_kasan_flag_stacktrace); early_param("kasan.stack_ring_size", early_kasan_flag_stack_ring_size); early_param("accept_memory", accept_memory_parse); early_param("page_table_check", early_page_table_check_param); sh_early_platform_init("earlytimer", &sh_cmt_device_driver); early_param_on_off("gbpages", "nogbpages", direct_gbpages, CONFIG_X86_DIRECT_GBPAGES); These are not necessarily bugs, given that some kernel boot parameters are intended for deep debugging rather than general use.

gcov: add gcov profiling infrastructure Enable the use of GCC's coverage testing tool gcov [1] with the Linux kernel. gcov may be useful for: * debugging (has this code been reached at all?) * test improvement (how do I change my test to cover these lines?) * minimizing kernel configurations (do I need this option if the associated code is never run?) The profiling patch incorporates the following changes: * change kbuild to include profiling flags * provide functions needed by profiling code * present profiling data as files in debugfs Note that on some architectures, enabling gcc's profiling option "-fprofile-arcs" for the entire kernel may trigger compile/link/ run-time problems, some of which are caused by toolchain bugs and others which require adjustment of architecture code. For this reason profiling the entire kernel is initially restricted to those architectures for which it is known to work without changes. This restriction can be lifted once an architecture has been tested and found compatible with gcc's profiling. Profiling of single files or directories is still available on all platforms (see config help text).

LoongArch: Make WriteCombine configurable for ioremap() LoongArch maintains cache coherency in hardware, but when paired with LS7A chipsets the WUC attribute (Weak-ordered UnCached, which is similar to WriteCombine) is out of the scope of cache coherency machanism for PCIe devices (this is a PCIe protocol violation, which may be fixed in newer chipsets). This means WUC can only used for write-only memory regions now, so this option is disabled by default, making WUC silently fallback to SUC for ioremap(). You can enable this option if the kernel is ensured to run on hardware without this bug. Kernel parameter writecombine=on/off can be used to override the Kconfig option.

of: property: Add functional dependency link from DT bindings Add device links after the devices are created (but before they are probed) by looking at common DT bindings like clocks and interconnects. Automatically adding device links for functional dependencies at the framework level provides the following benefits: - Optimizes device probe order and avoids the useless work of attempting probes of devices that will not probe successfully (because their suppliers aren't present or haven't probed yet). For example, in a commonly available mobile SoC, registering just one consumer device's driver at an initcall level earlier than the supplier device's driver causes 11 failed probe attempts before the consumer device probes successfully. This was with a kernel with all the drivers statically compiled in. This problem gets a lot worse if all the drivers are loaded as modules without direct symbol dependencies. - Supplier devices like clock providers, interconnect providers, etc need to keep the resources they provide active and at a particular state(s) during boot up even if their current set of consumers don't request the resource to be active. This is because the rest of the consumers might not have probed yet and turning off the resource before all the consumers have probed could lead to a hang or undesired user experience. Some frameworks (Eg: regulator) handle this today by turning off "unused" resources at late_initcall_sync and hoping all the devices have probed by then. This is not a valid assumption for systems with loadable modules. Other frameworks (Eg: clock) just don't handle this due to the lack of a clear signal for when they can turn off resources. This leads to downstream hacks to handle cases like this that can easily be solved in the upstream kernel. By linking devices before they are probed, we give suppliers a clear count of the number of dependent consumers. Once all of the consumers are active, the suppliers can turn off the unused resources without making assumptions about the number of consumers. By default we just add device-links to track "driver presence" (probe succeeded) of the supplier device. If any other functionality provided by device-links are needed, it is left to the consumer/supplier devices to change the link when they probe. kbuild test robot reported clang error about missing const Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Saravana Kannan <saravanak@google.com> Link: https://lore.kernel.org/r/20190904211126.47518-4-saravanak@google.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

security: Convert LSM into a static interface Convert LSM into a static interface, as the ability to unload a security module is not required by in-tree users and potentially complicates the overall security architecture. Needlessly exported LSM symbols have been unexported, to help reduce API abuse. Parameters for the capability and root_plug modules are now specified at boot. The SECURITY_FRAMEWORK_VERSION macro has also been removed. In a nutshell, there is no safe way to unload an LSM. The modular interface is thus unecessary and broken infrastructure. It is used only by out-of-tree modules, which are often binary-only, illegal, abusive of the API and dangerous, e.g. silently re-vectoring SELinux.

pm: boot time suspend selftest Boot-time test for system suspend states (STR or standby). The generic RTC framework triggers wakeup alarms, which are used to exit those states. - Measures some aspects of suspend time ... this uses "jiffies" until someone converts it to use a timebase that works properly even while timer IRQs are disabled. - Triggered by a command line parameter. By default nothing even vaguely troublesome will happen, but "test_suspend=mem" will give you a brief STR test during system boot. (Or you may need to use "test_suspend=standby" instead, if your hardware needs that.) This isn't without problems. It fires early enough during boot that for example both PCMCIA and MMC stacks have misbehaved. The workaround in those cases was to boot without such media cards inserted.

USB: usb-storage: add "quirks=" module parameter This patch (as1163b) adds a "quirks=" module parameter to usb-storage. This will allow people to make short-term changes to their unusual_devs list without rebuilding the entire driver. Testing will become much easier, and less-sophisticated users will be able to access their buggy devices after a simple config-file change instead of having to wait for a new kernel release. The patch also adds a documentation entry for usb-storage's "delay_use" parameter, which has been around for years but but was never listed among the kernel parameters.

x86/platform/uv: Disable UV BAU by default For several years, the common practice has been to boot UVs with the "nobau" parameter on the command line, to disable the BAU. We've decided that it makes more sense to just disable the BAU by default in the kernel, and provide the option to turn it on, if desired. For now, having the on/off switch doesn't buy us any more than just reversing the logic would, but we're working towards having the BAU enabled by default on UV4. When those changes are in place, having the on/off switch will make more sense than an enable flag, since the default behavior will be different depending on the system version. I've also added a bit of documentation for the new parameter to Documentation/kernel-parameters.txt.
