Add support for a legacy mapping where irq = (hwirq - first_hwirq + first_irq) so that a controller driver can allocate a fixed range of irq_descs and use a simple calculation to translate back and forth between linux and hw irq numbers. This is needed to use an irq_domain with many of the ARM interrupt controller drivers that manage their own irq_desc allocations. Ultimately the goal is to migrate those drivers to use the linear revmap, but doing it this way allows each driver to be converted separately which makes the migration path easier. This patch generalizes the IRQ_DOMAIN_MAP_LEGACY method to use (first_irq-first_hwirq) as the offset between hwirq and linux irq number, and adds checks to make sure that the hwirq number does not exceed range assigned to the controller.

Each revmap type has different arguments for setting up the revmap. This patch splits up the generator functions so that each revmap type can do its own setup and the user doesn't need to keep track of how each revmap type handles the arguments. This patch also adds a host_data argument to the generators. There are cases where the host_data pointer will be needed before the function returns. ie. the legacy map calls the .map callback for each irq before returning. v2: - Add void *host_data argument to irq_domain_add_*() functions - fixed failure to compile - Moved IRQ_DOMAIN_MAP_* defines into irqdomain.c Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Milton Miller <miltonm@bga.com> Tested-by: NOlof Johansson <olof@lixom.net>

This patch drops the powerpc-specific irq_map table and replaces it with directly using the irq_alloc_desc()/irq_free_desc() interfaces for allocating and freeing irq_desc structures. This patch is a preparation step for generalizing the powerpc-specific virq infrastructure to become irq_domains. As part of this change, the irq_big_lock is changed to a mutex from a raw spinlock. There is no longer any need to use a spin lock since the irq_desc allocation code is now responsible for the critical section of finding an unused range of irq numbers. The radix lookup table is also changed to store the irq_data pointer instead of the irq_map entry since the irq_map is removed. This should end up being functionally equivalent since only allocated irq_descs are ever added to the radix tree. v5: - Really don't ever allocate virq 0. The previous version could still do it if hint == 0 - Respect irq_virq_count setting for NOMAP. Some NOMAP domains cannot use virq values above irq_virq_count. - Use numa_node_id() when allocating irq_descs. Ideally the API should obtain that value from the caller, but that touches a lot of call sites so will be deferred to a follow-on patch. - Fix irq_find_mapping() to include irq numbers lower than NUM_ISA_INTERRUPTS. With the switch to irq_alloc_desc*(), the lowest possible allocated irq is now returned by arch_probe_nr_irqs(). v4: - Fix incorrect access to irq_data structure in debugfs code - Don't ever allocate virq 0 Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Milton Miller <miltonm@bga.com> Tested-by: NOlof Johansson <olof@lixom.net>

This patch drops the powerpc-specific irq_host structures and uses the common irq_domain strucutres defined in linux/irqdomain.h. It also fixes all the users to use the new structure names. Renaming irq_host to irq_domain has been discussed for a long time, and this patch is a step in the process of generalizing the powerpc virq code to be usable by all architecture. An astute reader will notice that this patch actually removes the irq_host structure instead of renaming it. This is because the irq_domain structure already exists in include/linux/irqdomain.h and has the needed data members.

Every arch calls: if (unlikely(current->audit_context)) audit_syscall_entry() which requires knowledge about audit (the existance of audit_context) in the arch code. Just do it all in static inline in audit.h so that arch's can remain blissfully ignorant. Signed-off-by: NEric Paris <eparis@redhat.com>

由 Eric Paris 提交于
The audit system previously expected arches calling to audit_syscall_exit to supply as arguments if the syscall was a success and what the return code was. Audit also provides a helper AUDITSC_RESULT which was supposed to simplify things by converting from negative retcodes to an audit internal magic value stating success or failure. This helper was wrong and could indicate that a valid pointer returned to userspace was a failed syscall. The fix is to fix the layering foolishness. We now pass audit_syscall_exit a struct pt_reg and it in turns calls back into arch code to collect the return value and to determine if the syscall was a success or failure. We also define a generic is_syscall_success() macro which determines success/failure based on if the value is < -MAX_ERRNO. This works for arches like x86 which do not use a separate mechanism to indicate syscall failure. We make both the is_syscall_success() and regs_return_value() static inlines instead of macros. The reason is because the audit function must take a void* for the regs. (uml calls theirs struct uml_pt_regs instead of just struct pt_regs so audit_syscall_exit can't take a struct pt_regs). Since the audit function takes a void* we need to use static inlines to cast it back to the arch correct structure to dereference it. The other major change is that on some arches, like ia64, MIPS and ppc, we change regs_return_value() to give us the negative value on syscall failure. THE only other user of this macro, kretprobe_example.c, won't notice and it makes the value signed consistently for the audit functions across all archs. In arch/sh/kernel/ptrace_64.c I see that we were using regs[9] in the old audit code as the return value. But the ptrace_64.h code defined the macro regs_return_value() as regs[3]. I have no idea which one is correct, but this patch now uses the regs_return_value() function, so it now uses regs[3]. For powerpc we previously used regs->result but now use the regs_return_value() function which uses regs->gprs[3]. regs->gprs[3] is always positive so the regs_return_value(), much like ia64 makes it negative before calling the audit code when appropriate.

This hooks dtc into Kbuild's dependency system. Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous lack of this feature recently caused me to have very confusing "git bisect" results. For ARM, it's obvious what to add to $(targets). I'm not familiar enough with other architectures to know what to add there. Powerpc appears to already add various .dtb files into $(targets), but the other archs may need something added to $(targets) to work.

Tracepoints should not be called inside an rcu_idle_enter/rcu_idle_exit region. Since pSeries calls H_CEDE in the idle loop, we were violating this rule. commit a7b152d5 (powerpc: Tell RCU about idle after hcall tracing) tried to work around it by delaying the rcu_idle_enter until after we called the hcall tracepoint, but there are a number of issues with it. The hcall tracepoint trampoline code is called conditionally when the tracepoint is enabled. If the tracepoint is not enabled we never call rcu_idle_enter. The idle_uses_rcu check was also done at compile time which breaks multiplatform builds. The simple fix is to avoid tracing H_CEDE and rely on other tracepoints and the hypervisor dispatch trace log to work out if we called H_CEDE. This fixes a hang during boot on pSeries.

Systems which use the fsl_pq_mdio driver need to specify an address for TBI PHY transactions such that the address does not conflict with any PHYs on the bus (all transactions to that address are directed to the onboard TBI PHY). The driver used to scan for a free address if no address was specified, however this ran into issues when the PHY Lib was fixed so that all MDIO transactions were protected by a mutex. As it is, the code was meant to serve as a transitional tool until the device trees were all updated to specify the TBI address. The best fix for the mutex issue was to remove the scanning code, but it turns out some of the newer SoCs have started to omit the tbi-phy node when SGMII is not being used. As such, these devices will now fail unless we add a tbi-phy node to the first mdio controller.
