[RFC/PATCH 4/4] Simplify xics direct/lpar irq_host setup

The xics code currently has a direct and lpar variant of xics_host_map, the only difference being which irq_chip they use. If we remember which irq_chip we're using we can combine these two routines. That also allows us to have a single irq_host_ops instead of two. Signed-off-by: Michael Ellerman

[PATCH] Make sure to of_node_get() the result of pci_device_to_OF_node()

pci_device_to_OF_node() returns the device node attached to a PCI device, but doesn't actually grab a reference - we need to do it ourselves. Signed-off-by: Michael Ellerman [EMAIL PROTECTED] --- arch/powerpc/platforms/cell/axon_msi.c |4 ++-- 1 files changed, 2 insertions(+), 2 deletions

[PATCH 1/7] Store the base address in dcr_host_t

In its current form, dcr_map() doesn't remember the base address you passed it, which means you need to store it somewhere else. Rather than adding the base to another struct it seems simpler to store it in the dcr_host_t. Signed-off-by: Michael Ellerman [EMAIL PROTECTED] --- arch/powerpc/sysdev

[PATCH 2/7] Update mpic to use dcr_host_t.base

Now that dcr_host_t contains the base address, we can use that in the mpic code, rather than storing it separately. Signed-off-by: Michael Ellerman [EMAIL PROTECTED] --- arch/powerpc/sysdev/mpic.c | 28 +++- include/asm-powerpc/mpic.h |6 -- 2 files changed, 11

[PATCH 3/7] Use dcr_host_t.base in ibm_emac_mal

This requires us to do a sort-of fake dcr_map(), so that base is set properly. This will be fixed/removed when the device-tree-aware emac driver is merged. Signed-off-by: Michael Ellerman [EMAIL PROTECTED] --- drivers/net/ibm_emac/ibm_emac_mal.c |5 - drivers/net/ibm_emac/ibm_emac_mal.h

[PATCH 5/7] Add dcr_host_t.base in dcr_read()/dcr_write()

Now that all users of dcr_read()/dcr_write() add the dcr_host_t.base, we can save them the trouble and do it in dcr_read()/dcr_write(). Signed-off-by: Michael Ellerman [EMAIL PROTECTED] --- arch/powerpc/platforms/cell/axon_msi.c |4 ++-- arch/powerpc/sysdev/mpic.c |4

[PATCH 7/7] Remove msic_dcr_read() and use dcr_map_reg() in axon_msi.c

msic_dcr_read() doesn't really do anything useful, just replace it with direct calls to dcr_read(). Use dcr_map_reg() in the axon_msi setup code, rather than essentially doing it by hand. Signed-off-by: Michael Ellerman [EMAIL PROTECTED] --- arch/powerpc/platforms/cell/axon_msi.c | 22

[PATCH 4/4] Inline u3msi_compose_msi_msg()

In the MPIC U3 MSI code, we call u3msi_compose_msi_msg() once for each MSI. This is overkill, as the address is per pci device, not per MSI. So setup the address once, and just set the data per MSI. Signed-off-by: Michael Ellerman [EMAIL PROTECTED] --- arch/powerpc/sysdev/mpic_u3msi.c | 24
