exit: Rename complete_and_exit to kthread_complete_and_exit

2021-12-13T18:04:45Z

Update complete_and_exit to call kthread_exit instead of do_exit. Change the name to reflect this change in functionality. All of the users of complete_and_exit are causing the current kthread to exit so this change makes it clear what is happening. Move the implementation of kthread_complete_and_exit from kernel/exit.c to to kernel/kthread.c. As this function is kthread specific it makes most sense to live with the kthread functions. There are no functional change. Signed-off-by: "Eric W. Biederman"

Make static usermode helper binaries constant

2017-01-19T11:59:45Z

There are a number of usermode helper binaries that are "hard coded" in the kernel today, so mark them as "const" to make it harder for someone to change where the variables point to.

PNP: make pnpbios core explicitly non-modular

2016-07-05T20:37:25Z

The Kconfig currently controlling compilation of this code is: config PNPBIOS bool "Plug and Play BIOS support" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modularity, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. Signed-off-by: Paul Gortmaker Signed-off-by: Rafael J. Wysocki

x86, drivers/pnpbios: Replace paravirt_enabled() check with legacy device check

2016-04-22T08:29:05Z

Since we are removing paravirt_enabled() replace it with a logical equivalent. Even though PNPBIOS is x86 specific we add an arch-specific type call, which can be implemented by any architecture to show how other legacy attribute devices can later be also checked for with other ACPI legacy attribute flags. This implicates the first ACPI 5.2.9.3 IA-PC Boot Architecture ACPI_FADT_LEGACY_DEVICES flag device, and shows how to add more. The reason pnpbios gets a defined structure and as such uses a different approach than the RTC legacy quirk is that ACPI has a respective RTC flag, while pnpbios does not. We fold the pnpbios quirk under ACPI_FADT_LEGACY_DEVICES ACPI flag use case, and use a struct of possible devices to enable future extensions of this. As per 0-day, this bumps the vmlinux size using i386-tinyconfig as follows: TOTAL TEXT init.text x86_early_init_platform_quirks() +32 +28 +28 +28 That's 4 byte overhead total, the rest is cleared out on init as its all __init text. v2: split out subarch handlng on switch to make it easier later to add other subarchs. The 'fall-through' switch handling can be confusing and we'll remove it later when we add handling for X86_SUBARCH_CE4100. v3: document vmlinux size impact as per 0-day, and also explain why pnpbios is treated differently than the RTC legacy feature.

pnpbios: bail out on strange errors

2015-01-25T17:17:59Z

A small number of systems respond to PnP dock queries with bogus values. This causes us to keep logging an error every 2 seconds. Instead of trying again just assume the BIOS is crapware and doesn't actually have dock functionality. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman
