      x86/acpi: Prevent out of bound access caused by broken ACPI tables · dad5ab0d
      由 Seunghun Han 提交于 
      The bus_irq argument of mp_override_legacy_irq() is used as the index into
the isa_irq_to_gsi[] array. The bus_irq argument originates from
ACPI_MADT_TYPE_IO_APIC and ACPI_MADT_TYPE_INTERRUPT items in the ACPI
tables, but is nowhere sanity checked.

That allows broken or malicious ACPI tables to overwrite memory, which
might cause malfunction, panic or arbitrary code execution.

Add a sanity check and emit a warning when that triggers.

      x86, mpparse, x86/acpi, x86/PCI, x86/dmi, SFI: Use memremap() for RAM mappings · f7750a79
      由 Tom Lendacky 提交于 
      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.

      由 Ingo Molnar 提交于 
      So there's a number of constants that start with "E820" but which
are not types - these create a confusing mixture when seen together
with 'enum e820_type' values:

	E820MAP
	E820NR
	E820_X_MAX
	E820MAX

To better differentiate the 'enum e820_type' values prefix them
with E820_TYPE_.

No change in functionality.

      x86/boot/e820: Create coherent API function names for E820 range operations · ab6bc04c
      由 Ingo Molnar 提交于 
      We have these three related functions:

 extern void e820_add_region(u64 start, u64 size, int type);
 extern u64  e820_update_range(u64 start, u64 size, unsigned old_type, unsigned new_type);
 extern u64  e820_remove_range(u64 start, u64 size, unsigned old_type, int checktype);

But it's not clear from the naming that they are 3 operations based around the
same 'memory range' concept. Rename them to better signal this, and move
the prototypes next to each other:

 extern void e820__range_add   (u64 start, u64 size, int type);
 extern u64  e820__range_update(u64 start, u64 size, unsigned old_type, unsigned new_type);
 extern u64  e820__range_remove(u64 start, u64 size, unsigned old_type, int checktype);

Note that this improved organization of the functions shows another problem that was easy
to miss before: sometimes the E820 entry type is 'int', sometimes 'unsigned int' - but this
will be fixed in a separate patch.

No change in functionality.

      x86/boot/e820: Rename update_e820() to e820__update_table() · 6464d294
      由 Ingo Molnar 提交于 
      update_e820() should have 'e820' as a prefix as most of the other E820
functions have - but it's also a bit unclear about its purpose, as
it's unclear what is updated - the whole table, or an entry?

Also, the name does not express that it's a trivial wrapper
around sanitize_e820_table() that also prints out the resulting
table.

So rename it to e820__update_table_print(). This also makes it
harmonize with the e820__update_table_firmware() function which
has a very similar purpose.

      由 Ingo Molnar 提交于 
      A commonly used lowlevel x86 header, asm/pgtable.h, includes asm/e820/api.h
spuriously, without making direct use of it.

Removing it is not simple: over the years various .c code learned to rely
on this indirect inclusion.

Remove the unnecessary include - this should speed up the kernel build a bit,
as a large header is not included anymore in totally unrelated code.

      x86/acpi: Prevent LAPIC id 0xff from being accounted · f3bf1dbe
      由 Thomas Gleixner 提交于 
      Yinghai reported that the recent changes to make the cpuid - nodeid
relationship permanent causes a cpuid ordering regression on a system which
has 2apic enabled..

The reason is that the ACPI local APIC parser has no sanity check for
apicid 0xff, which is an invalid id. So a CPU id for this invalid local
APIC id is allocated and therefor breaks the cpuid ordering.

Add a sanity check to acpi_parse_lapic() which ignores the invalid id.

      x86/acpi: Set persistent cpuid <-> nodeid mapping when booting · dc6db24d
      由 Gu Zheng 提交于 
      The whole patch-set aims at making cpuid <-> nodeid mapping persistent. So that,
when node online/offline happens, cache based on cpuid <-> nodeid mapping such as
wq_numa_possible_cpumask will not cause any problem.
It contains 4 steps:
1. Enable apic registeration flow to handle both enabled and disabled cpus.
2. Introduce a new array storing all possible cpuid <-> apicid mapping.
3. Enable _MAT and MADT relative apis to return non-present or disabled cpus' apicid.
4. Establish all possible cpuid <-> nodeid mapping.

This patch finishes step 4.

This patch set the persistent cpuid <-> nodeid mapping for all enabled/disabled
processors at boot time via an additional acpi namespace walk for processors.

3. Enable _MAT and MADT relative apis to return non-present or disabled cpus' apicid.
4. Establish all possible cpuid <-> nodeid mapping.

This patch finishes step 2.

In this patch, we introduce a new static array named cpuid_to_apicid[],
which is large enough to store info for all possible cpus.

And then, we modify the cpuid calculation. In generic_processor_info(),
it simply finds the next unused cpuid. And it is also why the cpuid <-> nodeid
mapping changes with node hotplug.

After this patch, we find the next unused cpuid, map it to an apicid,
and store the mapping in cpuid_to_apicid[], so that cpuid <-> apicid
mapping will be persistent.

And finally we will use this array to make cpuid <-> nodeid persistent.

cpuid <-> apicid mapping is established at local apic registeration time.
But non-present or disabled cpus are ignored.

In this patch, we establish all possible cpuid <-> apicid mapping when
registering local apic.

      x86/apic, ACPI: Remove the repeated lapic address override entry parsing · 6de42119
      由 Baoquan He 提交于 
      The ACPI MADT has a 32-bit field providing lapic address at which
each processor can access its lapic information. MADT also contains
an optional entry to provide a 64-bit address to override the 32-bit
one. However the current code does the lapic address override entry
parsing twice. One is in early_acpi_boot_init() because AMD NUMA need
get boot_cpu_id earlier. The other is in acpi_boot_init() which parses
all MADT entries.

So in this patch we remove the repeated code in the 2nd part.

Meanwhile print lapic override entry information like other MADT entry,
this will be added to boot log.

This patch is not supposed to change any runtime behavior, other than
improving kernel messages.

      x86/kernel: Audit and remove any unnecessary uses of module.h · 186f4360
      由 Paul Gortmaker 提交于 
      Historically a lot of these existed because we did not have
a distinction between what was modular code and what was providing
support to modules via EXPORT_SYMBOL and friends.  That changed
when we forked out support for the latter into the export.h file.

This means we should be able to reduce the usage of module.h
in code that is obj-y Makefile or bool Kconfig.  The advantage
in doing so is that module.h itself sources about 15 other headers;
adding significantly to what we feed cpp, and it can obscure what
headers we are effectively using.

Since module.h was the source for init.h (for __init) and for
export.h (for EXPORT_SYMBOL) we consider each obj-y/bool instance
for the presence of either and replace as needed.  Build testing
revealed some implicit header usage that was fixed up accordingly.

Note that some bool/obj-y instances remain since module.h is
the header for some exception table entry stuff, and for things
like __init_or_module (code that is tossed when MODULES=n).
