2021-06-07ARM: 9084/1: simplify the build rule of mach-types.hMasahiro Yamada1-2/+1
The directory of mach-types.h is created a couple of lines above: _dummy := $(shell [ -d '$(kapi)' ] || mkdir -p '$(kapi)') \ The 'mkdir -p' command is redundant. scripts/Kbuild.include defines real-prereqs as a shorthand for $(filter-out $(PHONY),$^). Let's use it to simplify the code. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

2021-06-07ARM: 9082/1: [v2] mark prepare_page_table as __initArnd Bergmann1-1/+1
In some configurations when building with gcc-11, prepare_page_table does not get inline, which causes a build time warning for a section mismatch: WARNING: modpost: vmlinux.o(.text.unlikely+0xce8): Section mismatch in reference from the function prepare_page_table() to the (unknown reference) .init.data:(unknown) The function prepare_page_table() references the (unknown reference) __initdata (unknown). This is often because prepare_page_table lacks a __initdata annotation or the annotation of (unknown) is wrong. Mark the function as __init to avoid the warning regardless of the inlining, and remove the 'inline' keyword. The compiler is free to ignore the 'inline' here and it doesn't result in better object code or more readable source.

2021-06-07ARM: update __swp_entry_to_pte() to use PTE_TYPE_FAULTRussell King (Oracle)1-1/+1
Swap entries use a faulting PTE which have the least two significant bits as zero. Due to this, the use of PTE_TYPE_FAULT was overlooked, but really should have been included in __swp_entry_to_pte(). Convert this macro to use PTE_TYPE_FAULT to properly document what is going on here, and use __pte() to convert the swp_entry_t to a pte_t. This results in no change to the resulting kernel image.

2021-06-04ARM: dts: imx53-ppd: add dma-info nodesFabien Lahoudere1-0/+2
GEHC CS ONE (codename is PPD), has multiple microcontrollers connected via UART controlling. UART2 is connected to an on-board microcontroller at 19200 baud, which constantly pushes critical data (so aging character detect interrupt will never trigger). This data must be processed at 50-200 Hz, so UART should return data in less than 5-20ms. With 1024 byte DMA buffer (and a constant data stream) the read operation instead needs 1024 byte / 19200 baud = 53.333ms, which is way too long (note: Worst case would be remote processor sending data with short pauses <= 7 characters, which would further increase this number). The current downstream kernel instead configures 24 bytes resulting in 1.25ms, but that is obviously not sensible for normal UART use cases and cannot be used as new default. The same device also has another microcontroller with a 4M baud connected to UART5 exchanging lots of data. For this the same mechanism can be used to increase the buffer size (downstream uses 4K instead of the default 1K) with potentially slightly reduced buffer count. At this baud rate latency is not an issue (4096 byte / 4M baud = 0.977 ms). Before increasing the default buffer count from 4 to 16 in 76c38d30fee7, this was required to avoid data loss. With the changed default it's a performance optimization.

2021-06-03kprobes: Do not increment probe miss count in the fault handlerNaveen N. Rao1-14/+0
Kprobes has a counter 'nmissed', that is used to count the number of times a probe handler was not called. This generally happens when we hit a kprobe while handling another kprobe. However, if one of the probe handlers causes a fault, we are currently incrementing 'nmissed'. The comment in fault handler indicates that this can be used to account faults taken by the probe handlers. But, this has never been the intention as is evident from the comment above 'nmissed' in 'struct kprobe': /*count the number of times this probe was temporarily disarmed */ unsigned long nmissed; Signed-off-by: Naveen N.

2021-06-03crypto: ixp4xx - convert to platform driverArnd Bergmann1-0/+26
The ixp4xx_crypto driver traditionally registers a bare platform device without attaching it to a driver, and detects the hardware at module init time by reading an SoC specific hardware register. Change this to the conventional method of registering the platform device from the platform code itself when the device is present, turning the module_init/module_exit functions into probe/release driver callbacks. This enables compile-testing as well as potentially having ixp4xx coexist with other ARMv5 platforms in the same kernel in the future.

2021-06-03ARM: 9081/1: fix gcc-10 thumb2-kernel regressionArnd Bergmann1-7/+9
When building the kernel wtih gcc-10 or higher using the CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE=y flag, the compiler picks a slightly different set of registers for the inline assembly in cpu_init() that subsequently results in a corrupt kernel stack as well as remaining in FIQ mode. If a banked register is used for the last argument, the wrong version of that register gets loaded into CPSR_c. When building in Arm mode, the arguments are passed as immediate values and the bug cannot happen. This got introduced when Daniel reworked the FIQ handling and was technically always broken, but happened to work with both clang and gcc before gcc-10 as long as they picked one of the lower registers. This is probably an indication that still very few people build the kernel in Thumb2 mode. Marek pointed out the problem on IRC, Arnd narrowed it down to this inline assembly and Russell pinpointed the exact bug. Change the constraints to force the final mode switch to use a non-banked register for the argument to ensure that the correct constant gets loaded. Another alternative would be to always use registers for the constant arguments to avoid the #ifdef that has now become more complex.

2021-06-03ARM: dts: aspeed: Set earlycon boot argumentJoel Stanley29-29/+29
Most of the aspeed boards have copied the 'earlyprink' string in the bootargs. However, there's no earlyprink driver configured in the defconfigs, so this does nothing. A combination of setting stdout in the chosen node and adding earlycon to bootargs causes early serial output to appear early. This changes all boards to use this option. The console=ttyS4,115200 option is still required, as this is used by the run time uart driver.
