2021-10-26irq: remove handle_domain_{irq,nmi}()Mark Rutland
Now that entry code handles IRQ entry (including setting the IRQ regs) before calling irqchip code, irqchip code can safely call generic_handle_domain_irq(), and there's no functional reason for it to call handle_domain_irq(). Let's cement this split of responsibility and remove handle_domain_irq() entirely, updating irqchip drivers to call generic_handle_domain_irq(). For consistency, handle_domain_nmi() is similarly removed and replaced with a generic_handle_domain_nmi() function which also does not perform any entry logic. Previously handle_domain_{irq,nmi}() had a WARN_ON() which would fire when they were called in an inappropriate context. So that we can identify similar issues going forward, similar WARN_ON_ONCE() logic is added to the generic_handle_*() functions, and comments are updated for clarity and consistency.

2021-10-25irq: arm: perform irqentry in entry codeMark Rutland
In preparation for removing HANDLE_DOMAIN_IRQ_IRQENTRY, have arch/arm perform all the irqentry accounting in its entry code. For configurations with CONFIG_GENERIC_IRQ_MULTI_HANDLER, we can use generic_handle_arch_irq(). Other than asm_do_IRQ(), all C calls to handle_IRQ() are from irqchip handlers which will be called from generic_handle_arch_irq(), so to avoid double accounting IRQ entry, the entry logic is moved from handle_IRQ() into asm_do_IRQ(). For ARMv7M the entry assembly is tightly coupled with the NVIC irqchip, and while the entry code should logically live under arch/arm/, moving the entry logic there makes things more convoluted. So for now, place the entry logic in the NVIC irqchip, but separated into a separate function to make the split of responsibility clear. For all other configurations without CONFIG_GENERIC_IRQ_MULTI_HANDLER, IRQ entry is already handled in arch code, and requires no changes. There should be no functional change as a result of this patch.

2021-10-25irq: add a (temporary) CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRYMark Rutland
Going forward we want architecture/entry code to perform all the necessary work to enter/exit IRQ context, with irqchip code merely handling the mapping of the interrupt to any handler(s). Among other reasons, this is necessary to consistently fix some longstanding issues with the ordering of lockdep/RCU/tracing instrumentation which many architectures get wrong today in their entry code. Importantly, rcu_irq_{enter,exit}() must be called precisely once per IRQ exception, so that rcu_is_cpu_rrupt_from_idle() can correctly identify when an interrupt was taken from an idle context which must be explicitly preempted. Currently handle_domain_irq() calls rcu_irq_{enter,exit}() via irq_{enter,exit}(), but entry code needs to be able to call rcu_irq_{enter,exit}() earlier for correct ordering across lockdep/RCU/tracing updates for sequences such as: lockdep_hardirqs_off(CALLER_ADDR0); rcu_irq_enter(); trace_hardirqs_off_finish(); To permit each architecture to be converted to the new style in turn, this patch adds a new CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY selected by all current users of HANDLE_DOMAIN_IRQ, which gates the existing behaviour. When CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY is not selected, handle_domain_irq() requires entry code to perform the irq_{enter,exit}() work, with an explicit check for this matching the style of handle_domain_nmi(). Subsequent patches will: 1) Add the necessary IRQ entry accounting to each architecture in turn, dropping CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY from that architecture's Kconfig. 2) Remove CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY once it is no longer selected. 3) Convert irqchip drivers to consistently use generic_handle_domain_irq() rather than handle_domain_irq(). 4) Remove handle_domain_irq() and CONFIG_HANDLE_DOMAIN_IRQ. ... which should leave us with a clear split of responsiblity across the entry and irqchip code, making it possible to perform additional cleanups and fixes for the aforementioned longstanding issues with entry code. There should be no functional change as a result of this patch. Signed-off-by: Mark Rutland <mark.rutland@arm.com> Reviewed-by: Marc Zyngier <maz@kernel.org> Cc: Thomas Gleixner <tglx@linutronix.de>
2021-09-22entry: rseq: Call rseq_handle_notify_resume() in tracehook_notify_resume()Sean Christopherson
Invoke rseq_handle_notify_resume() from tracehook_notify_resume() now that the two function are always called back-to-back by architectures that have rseq. The rseq helper is stubbed out for architectures that don't support rseq, i.e. this is a nop across the board. Note, tracehook_notify_resume() is horribly named and arguably does not belong in tracehook.h as literally every line of code in it has nothing to do with tracing. But, that's been true since commit a42c6ded827d ("move key_repace_session_keyring() into tracehook_notify_resume()") first usurped tracehook_notify_resume() back in 2012. Punt cleaning that mess up to future patches. No functional change intended.

There are a lot of uses of memblock_find_in_range() along with memblock_reserve() from the times memblock allocation APIs did not exist. memblock_find_in_range() is the very core of memblock allocations, so any future changes to its internal behaviour would mandate updates of all the users outside memblock. Replace the calls to memblock_find_in_range() with an equivalent calls to memblock_phys_alloc() and memblock_phys_alloc_range() and make memblock_find_in_range() private method of memblock. This simplifies the callers, ensures that (unlikely) errors in memblock_reserve() are handled and improves maintainability of memblock_find_in_range().

Changing m68k fsp040_die to use force_sigsegv(SIGSEGV) instead of calling do_exit directly is interesting only in that it is nearly the most difficult of the incorrect uses of do_exit to remove.

2021-08-30ixp4xx_eth: make ptp support a platform driverArnd Bergmann
After the recent ixp4xx cleanups, the ptp driver has gained a build failure in some configurations: drivers/net/ethernet/xscale/ptp_ixp46x.c: In function 'ptp_ixp_init': drivers/net/ethernet/xscale/ptp_ixp46x.c:290:51: error: 'IXP4XX_TIMESYNC_BASE_VIRT' undeclared (first use in this function) Avoid the last bit of hardcoded constants from platform headers by turning the ptp driver bit into a platform driver and passing the IRQ and MMIO address as resources. This is a bit tricky: - The interface between the two drivers is now the new ixp46x_ptp_find() function, replacing the global ixp46x_phc_index variable. The call is done as late as possible, in hwtstamp_set(), to ensure that the ptp device is fully probed. - As the ptp driver is now called by the network driver, the link dependency is reversed, which in turn requires a small Makefile hack - The GPIO number is still left hardcoded. This is clearly not great, but it can be addressed later. Note that commit 98ac0cc270b7 ("ARM: ixp4xx: Convert to MULTI_IRQ_HANDLER") changed the IRQ number to something meaningless. Passing the correct IRQ in a resource fixes this. - When the PTP driver is disabled, ethtool .get_ts_info() now correctly lists only software timestamping regardless of the hardware.

2021-08-20ARM: 9110/1: oabi-compat: fix oabi epoll sparse warningArnd Bergmann
As my patches change the oabi epoll definition, I received a report from the kernel test robot about a pre-existing issue with a mismatched __poll_t type. The OABI code was correct when it was initially added in linux-2.16, but a later (also correct) change to the generic __poll_t triggered a type mismatch warning from sparse. As __poll_t is always 32-bit bits wide and otherwise compatible, using this instead of __u32 in the oabi_epoll_event definition is a valid workaround.

There are no remaining callers of set_fs(), so just remove it along with all associated code that operates on thread_info->addr_limit. There are still further optimizations that can be done: - In get_user(), the address check could be moved entirely into the out of line code, rather than passing a constant as an argument, - I assume the DACR handling can be simplified as we now only change it during user access when CONFIG_CPU_SW_DOMAIN_PAN is set, but not during set_fs().

2021-08-20ARM: 9112/1: uaccess: add __{get,put}_kernel_nofaultArnd Bergmann
These mimic the behavior of get_user and put_user, except for domain switching, address limit checking and handling of mismatched sizes, none of which are relevant here. To work with pre-Armv6 kernels, this has to avoid TUSER() inside of the new macros, the new approach passes the "t" string along with the opcode, which is a bit uglier but avoids duplicating more code. As there is no __get_user_asm_dword(), I work around it by copying 32 bit at a time, which is possible because the output size is known.
