mm: remove include/linux/bootmem.h

2018-10-31T15:54:16+00:00

Move remaining definitions and declarations from include/linux/bootmem.h
into include/linux/memblock.h and remove the redundant header.

The includes were replaced with the semantic patch below and then
semi-automated removal of duplicated '#include

x86/boot: Fix memremap() related build failure

2017-07-20T09:37:58+00:00

The following commit:

  5997efb96756 ("x86/boot: Use memremap() to map the MPF and MPC data")

causes new build failures on certain randconfigs:

  drivers/sfi/sfi_core.c: In function ‘sfi_map_memory’:
  drivers/sfi/sfi_core.c:104:10: error: implicit declaration of function ‘memremap’ [-Werror=implicit-function-declaration]
  drivers/sfi/sfi_core.c:104:31: error: ‘MEMREMAP_WB’ undeclared (first use in this function)

This is a case of parasitic header dependencies: the sfi_core.c file indirectly
includes  for typical - but not all configs.

Including  explicitly solves the build failure.

x86, mpparse, x86/acpi, x86/PCI, x86/dmi, SFI: Use memremap() for RAM mappings

2017-07-18T09:37:58+00:00

The ioremap() function is intended for mapping MMIO. For RAM, the
memremap() function should be used. Convert calls from ioremap() to
memremap() when re-mapping RAM.

This will be used later by SME to control how the encryption mask is
applied to memory mappings, with certain memory locations being mapped
decrypted vs encrypted.

SFI: use ioremap_cache() instead of ioremap()

2011-01-12T04:27:25+00:00

We copied ACPI's oversight of using ioremap() and creating
non-cached table mappings when we should have been using
ioremap_cache().

SFI: do not return freed pointer

2010-06-01T16:04:35+00:00

We never actually use the return value of sfi_sysfs_install_table() but
it still seems wrong to return a freed pointer.

SFI: add sysfs interface for SFI tables.

2010-05-27T16:46:20+00:00

Analogous to ACPI's /sys/firmware/acpi/tables/...

create /sys/firmware/sfi/tables/

The tables are primariy for the kernel,
but sometimes it is useful for user-space to be
able to read them.

SFI: add support for v0.81 spec

2010-05-25T15:41:43+00:00

There are 2 major changes from v0.81 to v0.7:
1. Consolidating the SPIB/I2CB tables into a new DEVS table,
   which is more expandable and can support other bus types
   than spi/i2c.
2. Creating a new GPIO table, which list all the GPIO pins
   used in the platform.

However, to avoid breaking current platforms who use SFI v0.7
version firmware, the definitions for SPIB/I2CB will still
be kept for a while

SFI: remove __init from sfi_verify_table

sfi_verify_table() is called at runtime, and thus cannot be __init
