The kernel CONFIG_ORC_UNWINDER option enables the ORC unwinder, which is

The kernel CONFIG_UNWINDER_ORC option enables the ORC unwinder, which is

similar in concept to a DWARF unwinder.  The difference is that the

format of the ORC data is much simpler than DWARF, which in turn allows

the ORC unwinder to be much simpler and faster.

Architecture defines a 64-bit virtual address. Implementations can support

less. Currently supported are 48- and 57-bit virtual addresses. Bits 63

through to the most-significant implemented bit are set to either all ones

or all zero. This causes hole between user space and kernel addresses.

through to the most-significant implemented bit are sign extended.

This causes hole between user space and kernel addresses if you interpret them

as unsigned.

The direct mapping covers all memory in the system up to the highest

memory address (this means in some cases it can also include PCI memory

the processes using the page fault handler, with init_top_pgt as

reference.

Current X86-64 implementations support up to 46 bits of address space (64 TB),

which is our current limit. This expands into MBZ space in the page tables.

We map EFI runtime services in the 'efi_pgd' PGD in a 64Gb large virtual

memory window (this size is arbitrary, it can be raised later if needed).

The mappings are not part of any other kernel PGD and are only available

Note that if CONFIG_RANDOMIZE_MEMORY is enabled, the direct mapping of all

physical memory, vmalloc/ioremap space and virtual memory map are randomized.

Their order is preserved but their base will be offset early at boot time.
