Christophe JAILLET July 27, 2020, 10:34 a.m. UTC 
The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'radeon_gart_table_ram_alloc()' GFP_KERNEL
can be used because its callers already use this flag.

Both 'r100_pci_gart_init()' (r100.c) and 'rs400_gart_init()' (rs400.c)
call 'radeon_gart_init()'.
This function uses 'vmalloc'.
