of: fdt: Remove weak early_init_dt_mark_hotplug_memory_arch()

2021-08-15T14:56:03Z

Commit 41a9ada3e6b4253f ("of/fdt: mark hotpluggable memory") introduced two (for systems with and without memblock) weak versions of early_init_dt_mark_hotplug_memory_arch(), that could be overridden by an architecture-specific version. However, no overrides ever emerged. Later, commit aca52c3983891060 ("mm: remove CONFIG_HAVE_MEMBLOCK") removed the non-memblock version. Remove early_init_dt_mark_hotplug_memory_arch(), and replace it by a direct call to memblock_mark_hotplug().

Commit e7ae8d174eec0b3b ("MIPS: replace add_memory_region with memblock") removed the last architecture-specific override of early_init_dt_reserve_memory_arch(). Convert the common implementation from a weak global function to a static function.

of/fdt: Remove dead code and mark functions with __init

2019-05-24T21:39:14Z

Some functions in here are never called, and others are only called during __init. Remove the dead code and some dead exports for functions that don't exist (I'm looking at you of_fdt_get_string!). Mark some functions with __init so we can throw them away after we boot up and poke at the FDT blob too. Cc: Hsin-Yi Wang Signed-off-by: Stephen Boyd Signed-off-by: Rob Herring

x86/headers: Fix -Wmissing-prototypes warning

2018-11-23T06:59:59Z

When building the kernel with W=1 we get a lot of -Wmissing-prototypes warnings, which are trivial in nature and easy to fix - and which may mask some real future bugs if the prototypes get out of sync with the function definition. This patch fixes most of -Wmissing-prototypes warnings which are in the root directory of arch/x86/kernel, not including the subdirectories. These are the warnings fixed in this patch: arch/x86/kernel/signal.c:865:17: warning: no previous prototype for ‘sys32_x32_rt_sigreturn’ [-Wmissing-prototypes] arch/x86/kernel/signal_compat.c:164:6:

of/fdt: use memblock_virt_alloc for early alloc

2018-01-08T14:24:34Z

memblock_virt_alloc() works for both memblock and bootmem, so use it and make early_init_dt_alloc_memory_arch a static function. The arches using bootmem define early_init_dt_alloc_memory_arch as either: __alloc_bootmem(size, align, __pa(MAX_DMA_ADDRESS)) or: alloc_bootmem_align(size, align) Both of these evaluate to the same thing as does memblock_virt_alloc for bootmem. So we can disable the arch specific functions by making early_init_dt_alloc_memory_arch static and they can be removed in subsequent commits. Cc: Frank Rowand Signed-off-by: Rob Herring

of/fdt: mark hotpluggable memory

2016-12-13T02:55:07Z

When movable nodes are enabled, any node containing only hotpluggable memory is made movable at boot time. On x86, hotpluggable memory is discovered by parsing the ACPI SRAT, making corresponding calls to memblock_mark_hotplug(). If we introduce a dt property to describe memory as hotpluggable, configs supporting early fdt may then also do this marking and use movable nodes.
