Subject: [PATCH] RISC-V: Move all address space definition macros to one place

If both CONFIG_KASAN and CONFIG_SPARSEMEM_VMEMMAP are set, we get the
|
|
||||||
following compilation error.
|
|
||||||
|
|
||||||
---------------------------------------------------------------
|
|
||||||
./arch/riscv/include/asm/pgtable-64.h: In function ‘pud_page’:
|
|
||||||
./include/asm-generic/memory_model.h:54:29: error: ‘vmemmap’ undeclared
|
|
||||||
(first use in this function); did you mean ‘mem_map’?
|
|
||||||
#define __pfn_to_page(pfn) (vmemmap + (pfn))
|
|
||||||
^~~~~~~
|
|
||||||
./include/asm-generic/memory_model.h:82:21: note: in expansion of
|
|
||||||
macro ‘__pfn_to_page’
|
|
||||||
|
|
||||||
#define pfn_to_page __pfn_to_page
|
|
||||||
^~~~~~~~~~~~~
|
|
||||||
./arch/riscv/include/asm/pgtable-64.h:70:9: note: in expansion of macro
|
|
||||||
‘pfn_to_page’
|
|
||||||
return pfn_to_page(pud_val(pud) >> _PAGE_PFN_SHIFT);
|
|
||||||
---------------------------------------------------------------
|
|
||||||
|
|
||||||
Fix the compliation errors by moving all the address space definition
|
|
||||||
macros before including pgtable-64.h.
