With the base stored in dcr_host_t, there's no need for callers to pass the dcr_n into dcr_unmap(). In fact this removes the possibility of them passing the incorrect value, which would then be iounmap()'ed.

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(). As some background to why we just went through all this jiggery-pokery, benh sayeth: Initially the goal of the dcr_read/dcr_write routines was to operate like mfdcr/mtdcr which take absolute DCR numbers. The reason is that on 4xx hardware, indirect DCR access is a pain (goes through a table of instructions) and it's useful to have the compiler resolve an absolute DCR inline. We decided that wasn't worth the API bastardisation since most places where absolute DCR values are used are low level 4xx-only code which may as well continue using mfdcr/mtdcr, while the new API is designed for device "instances" that can exist on 4xx and Axon type platforms and may be located at variable DCR offsets.

pxa_gpio_mode() is a universal call that fiddles with the GAFR (gpio alternate function register.) GAFR does not exist on PXA3 CPUs, but instead the alternate functions are controlled via the MFP support code. Platforms are expected to configure the MFP according to their needs in their platform support code rather than drivers. We extend this idea to the GAFR, and make the gpio_direction_*() functions purely operate on the GPIO level. This means platform support code is entirely responsible for configuring the GPIOs alternate functions on all PXA CPU types. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

sched.o gets smaller and faster if we compile it with -fomit-frame-pointers, so make this a config option. The cost is the loss of multi-depth wchan lookups - but SysRq-T is a sufficient replacement for them anyway, so their utility is much lower these days. the size difference is significant: text data bss dec hex filename 34005 3462 24 37491 9273 sched.o.before 33470 3462 24 36956 905c sched.o.after Signed-off-by: NIngo Molnar <mingo@elte.hu> Signed-off-by: NPeter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: NMike Galbraith <efault@gmx.de> Reviewed-by: NThomas Gleixner <tglx@linutronix.de>

The 64bit SMP bootup is slightly different to the 32bit one. It enables the boot CPU local APIC timer before all CPUs are brought up. Some AMD C1E systems have the C1E feature flag only set in the secondary CPU. Due to the early enable of the boot CPU local APIC timer the APIC timer is registered as a fully functional device. When we detect the wreckage during the bringup of the secondary CPU, we need to force the boot CPU into broadcast mode. Check the C1E caused APIC timer disable, when the secondary APIC timer is initialized. If the boot CPU APIC timer was registered as a functional clock event device, then fix this up and utilize the CLOCK_EVT_NOTIFY_BROADCAST_FORCE mechanism to force the already registered boot CPU APIC timer into broadcast mode. Tested by force injecting the failure mode. Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

All the users go through virt_irq_to_bucket() and essentially want to go from a virt_irq to an INO, but we have a way to do that already via virt_to_real_irq_table[].dev_ino. This also allows us to kill both virt_to_real_irq() and virt_irq_to_bucket(). Signed-off-by: NDavid S. Miller <davem@davemloft.net>

We were simply concatenating the devhandle and devino and using that as the cookie, which defeats the entire purpose of the VIRQ hypervisor interfaces. Now that we use physical addresses for the INO buckets, we can allocate them dynamically for VIRQs and encode the cookies as ~__pa(bucket). This allows us to test for and decode the cookie with a simple: brlz $reg1, 1f xnor $reg1, %g0, $reg2 sequence. This works because bit 64 is never set in traditional INO vectors, and it is also never set in a physical address. So xnor'ing the physical address of the bucket always gives us a negative number, and thus a unique condition we can test cheaply. Inspired by ideas from Greg Onufer. Signed-off-by: NDavid S.

Currently we chain IVEC entries using 32-bit "pointers" because we know that the ivector_table is in the main kernel image, thus below 4GB. This uses proper 64-bit pointers instead. Whilst this bloats up the kernel image size, this sets the infrastructure necessary to significantly shrink the kernel size by using physical addresses and dynamically allocating the ivector table.

This also makes us use the MSI queues correctly. Each MSI queue is serviced by a normal sun4u/sun4v INO interrupt handler. This handler runs the MSI queue and dispatches the virtual interrupts indicated by arriving MSIs in that MSI queue. All of the common logic is placed in pci_msi.c, with callbacks to handle the PCI controller specific aspects of the operations. This common infrastructure will make it much easier to add MSG support.

Thanks to Tom Callaway for the excellent bug report and test case. sys_ipc() has several problems, most to due with semaphore call handling: 1) 'err' return should be a 'long' 2) "union semun" is passed in a register on 64-bit compared to 32-bit which provides it on the stack and therefore by reference 3) Second and third arguments to SEMCTL are swapped compared to 32-bit.

The name field of of_platform_driver is just copied into the included device_driver. By not overriding an already initialised device_driver name, we can convert the drivers over time to stop using the of_platform_driver name.

Added asm-sparc/irqflags.h and moved irq related code from system.h to it. Renamed local_irq functions to raw_local_irq in irq.c. Modified system.h to include linux/irqflags.h which includes asm/irqflags.h. Added TRACE_IRQFLAGS_SUPPORT to Kconfig.debug. This is the first step in adding IRQ-flags state tracing as outlined in Documentation/irqflags-tracing.txt. These changes should be harmless because they just move things around and rename them. The next step is making the lowlevel entry code modifications which to be honest are beyond my capabilities at this point. Boot tested on an ss20 running an SMP kernel.
