Imapct: add a new struct member to 'struct protection_domain' When using protection domains for dma_ops and KVM its better to know for which subsystem it was allocated. Add a flags member to struct protection domain for that purpose. Signed-off-by:Joerg Roedel <joerg.roedel@amd.com>

Joerg Roedel authored
Impact: save unneeded logic to add and remove domains to the list The removal of a protection domain from the iommu_pd_list is not necessary. Another benefit is that we save complexity because we don't have to readd it later when the device no longer uses the domain. Signed-off-by: -

Impact: change code to free pagetables from protection domains The dma_ops_free_pagetable function can only free pagetables from dma_ops domains. Change that to free pagetables of pure protection domains. Signed-off-by: -

* i8k-updates: i8k: Add Dell Vostro systems i8k: Enable i8k on Dell Precision Systems
-
Federico Heinz authored
This trivial patch adds support for i8k on the new Dell Vostro models. I tested it on my Vostro 1400, and it works. It does print a warning when loading the module: i8k: unable to get SMM BIOS version But I couldn't figure out how to fix that. The module seems to work fine, anyway... Signed-off-by:

Add flag value UPF_FIXED_TYPE which specifies that the UART type is known and should not be probed. For this case the UARTs properties are just copied out of the uart_config entry. This allows us to keep SOC specific 8250 probe code out of 8250.c. In this case we know the serial hardware will not be changing as it is on the same silicon as the CPU, and we can specify it with certainty in the board/cpu setup code. The alternative is to load up 8250.c with a bunch of OCTEON specific special cases in the probing code. Signed-off-by:

In order to use Cavium OCTEON specific serial i/o drivers, we first patch the 8250 driver to use replaceable I/O functions. Compatible I/O functions are added for existing iotypeS. An added benefit of this change is that it makes it easy to factor some of the existing special cases out to board/SOC specific support code. The alternative is to load up 8250.c with a bunch of OCTEON specific iotype code and bug work-arounds. Signed-off-by:

In serial8250_isa_init_ports(), the port's lock is initialized. We should not overwrite it. In early_serial_setup(), only copy in the fields we need. Since the early console code only uses a subset of the fields, these are sufficient. Signed-off-by:

Move the tty_port and uart_info bits around a little. By embedding the uart_info into the uart_port we get rid of lots of corner case testing and also get the ability to go port<->state<->info which is a bit more elegant than the current data structures. Downsides - we allocate a tiny bit more memory for unused ports, upside we've removed as much code as it saved for most users.. Signed-off-by:

In the commit below a new struct serial_rs485 was introduced for a new ioctl: commit c26c56c0 Author: Alan Cox <alan@redhat.com> Date: Mon Oct 13 10:37:48 2008 +0100 tty: Cris has a nice RS485 ioctl so we should steal it This structure uses the __u32 types for some of its members, which leads to the following compile error: $ cc -I.../include -c X.c In file included from X.c:2: .../include/linux/serial.h:185: error: expected specifier-qualifier-list before ‘__u32’ $ It seems that these types are appropriate for this structure as it is to be exposed to userspace. These types are available via linux/types.h so move the include of that outside the __KERNEL__ section. Signed-off-by:Andy Whitcroft <apw@canonical.com> Signed-off-by:
