Hi Thierry,

This is another regression from your asm-generic change in arm64. We
are now lacking a working pci_iomap function after you removed the
'select GENERIC_IOMAP' statement.

For all I can tell, this is the correct solution (note GENERIC_PCI_IOMAP
instead of GENERIC_IOMAP):

diff --git a/arch/arm64/Kconfig b/arch/arm64/Kconfig
index 37cd23625708..bc8879c283b9 100644
--- a/arch/arm64/Kconfig
+++ b/arch/arm64/Kconfig
@@ -25,6 +25,7 @@ config ARM64
        select GENERIC_EARLY_IOREMAP
        select GENERIC_IRQ_PROBE
        select GENERIC_IRQ_SHOW
+       select GENERIC_PCI_IOMAP
        select GENERIC_SCHED_CLOCK
        select GENERIC_SMP_IDLE_THREAD
        select GENERIC_STRNCPY_FROM_USER


Any comments?
