This patchset originally implemented relocatable kernel support but now         
also moves the kernel mapping into the vmalloc zone.                            
The first patch explains why we need to move the kernel into vmalloc            
zone (instead of memcpying it around). That patch should ease KASLR             
implementation a lot.                                                           
The second patch allows to build relocatable kernels but is not selected        
by default.                                                                     
The third and fourth patches take advantage of an already existing powerpc      
script that checks relocations at compile-time, and uses it for riscv.          
Changes in v5:
  * Add "static __init" to create_kernel_page_table function as reported by
    Kbuild test robot
  * Add reviewed-by from Zong
  * Rebase onto v5.7

Changes in v4:                                                                  
  * Fix BPF region that overlapped with kernel's as suggested by Zong           
  * Fix end of module region that could be larger than 2GB as suggested by Zong 
  * Fix the size of the vm area reserved for the kernel as we could lose        
    PMD_SIZE if the size was already aligned on PMD_SIZE                        
  * Split compile time relocations check patch into 2 patches as suggested by 
  * Applied Reviewed-by from Zong and Anup                                      
Changes in v3:                                                                  
  * Move kernel mapping to vmalloc                                              
Changes in v2:                                                                  
  * Make RELOCATABLE depend on MMU as suggested by Anup                         
  * Rename kernel_load_addr into kernel_virt_addr as suggested by Anup          
  * Use __pa_symbol instead of __pa, as suggested by Zong                       
  * Rebased on top of v5.6-rc3                                                  
  * Tested with sv48 patchset                                                   
  * Add Reviewed/Tested-by from Zong and Anup
