PNP: isapnp: make core more explicitly non-modular

2016-08-16T20:53:59Z

The Makefile currently controlling compilation of this code is: obj-y += pnp.o pnp-y := core.o compat.o ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. We don't replace module.h with init.h since the file already has that. But we do add moduleparam.h since the file does use module_param().

x86/uaccess: Move thread_info::addr_limit to thread_struct

2016-07-15T08:26:30Z

struct thread_info is a legacy mess. To prepare for its partial removal, move thread_info::addr_limit out. As an added benefit, this way is simpler.

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

pnp: pnpbios: Add explicit X86_32 dependency to PNPBIOS

2016-05-02T14:48:20Z

The PNPBIOS driver requires preprocessor defines (located in include/asm/segment.h) only declared if the architecture is set to X86_32. If the architecture is set to X86_64, the PNPBIOS driver will not build properly. The X86 dependecy for the PNPBIOS configuration option is changed to an explicit X86_32 dependency in order to prevent an attempt to build for an unsupported architecture. Acked-by: Rafael J.

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.

PNP / ACPI: add ACPI_RESOURCE_TYPE_SERIAL_BUS as a valid type

An error message is printed for resources of type 19, which is a valid supported resource type. The Firmware Test Suite tool (fwts) reports this as a test failure.
