commit e561e472 upstream. The platform's RNG must be available before random_init() in order to be useful for initial seeding, which in turn means that it needs to be called from setup_arch(), rather than from an init call. Fortunately, each platform already has a setup_arch function pointer, which means it's easy to wire this up. This commit also removes some noisy log messages that don't add much.

commit 53632ba8 upstream. If CONFIG_TRIM_UNUSED_KSYMS is enabled and the kernel is built from a pristine state, the vmlinux is linked twice. Commit 3fdc7d3f ("kbuild: link vmlinux only once for CONFIG_TRIM_UNUSED_KSYMS") explains why this happens, but it did not fix the issue at all. Now I realized I had applied a wrong patch. In v1 patch [1], the autoksyms_recursive target correctly recurses to "$(MAKE) -f $(srctree)/Makefile autoksyms_recursive". In v2 patch [2], I accidentally dropped the diff line, and it recurses to "$(MAKE) -f $(srctree)/Makefile vmlinux". Restore the code I intended in v1.

commit 9de74996 upstream. Some servers do not allow null netname contexts, which would cause multichannel to revert to single channel when mounting to some servers (e.g. Azure xSMB).

commit ab66fdac upstream. Build ID events associate a file name with a build ID. However, when using perf inject, there is no guarantee that the file on the current machine at the current time has that build ID. Fix by comparing the build IDs and skip adding to the cache if they are different.

commit 93a8ba2a upstream. Contrary to what was believed at the time, the ramp delay of 150us is not plenty for the PU LDO with the default step time of 512 pulses of the 24MHz clock. Measurements have shown that after enabling the LDO the voltage on VDDPU_CAP jumps to ~750mV in the first step and after that the regulator executes the normal ramp up as defined by the step size control. This means it takes the regulator between 360us and 370us to ramp up to the nominal 1.15V voltage for this power domain. With the old setting of the ramp delay the power up of the PU GPC domain would happen in the middle of the regulator ramp with the voltage being at around 900mV. Apparently this was enough for most units to properly power up the peripherals in the domain and execute the reset. Some units however, fail to power up properly, especially when the chip is at a low temperature. In that case any access to the GPU registers would yield an incorrect result with no way to recover from this situation. Change the ramp delay to 380us to cover the measured ramp up time with a bit of additional slack.

commit e9ed22e6 upstream. Anonymous pages are allocated with the shared mappings colouring, SHM_COLOUR. Since the alias boundary on machines with PA8800 and PA8900 processors is unknown, flush_user_cache_page() might not flush all mappings of a shared anonymous page. Flushing the whole data cache flushes all mappings. This won't fix all coherency issues with shared mappings but it seems to work well in practice. I haven't seen any random memory faults in almost a month on a rp3440 running as a debian buildd machine. There is a small preformance hit. Signed-off-by:

commit 04805839 upstream. Since commit 9bcf15f7 ("iio: adc: axp288: Fix TS-pin handling") we preserve the bias current set by the firmware at boot. This fixes issues we were seeing on various models. Some models like the Nuvision Solo 10 Draw tablet actually need the old hardcoded 80ųA bias current for battery temperature monitoring to work properly. Add a quirk entry for the Nuvision Solo 10 Draw to the DMI quirk table to restore setting the bias current to 80ųA on this model.

commit bc05f30f upstream. If the vrefint calibration is zero, the vrefint channel output value cannot be computed. Currently, in such case, the raw conversion value is returned, which is not relevant. Do not expose the vrefint channel when the output value cannot be computed, instead.

commit 99bded02 upstream. The check for spurious IRQs introduced in 695e2f5c assumed that the bits in the control and status registers are aligned. This is true for the H7 and MP1 version, but not the F4. The interrupt was then never handled on the F4. Instead of increasing the complexity of the comparison and check each bit specifically, we remove this check completely and rely on the generic handler for spurious IRQs.

commit d2214cca upstream. The irq handler was only checking the mask for the first ADCs in the case of the F4 and H7 generation, since it was iterating up to the num_irq value. This patch add the maximum number of ADC in the common register, which map to the number of entries of eoc_msk and ovr_msk in stm32_adc_common_regs. This allow the handler to check all ADCs in that module. Tested on a STM32F429NIH6. Fixes: 695e2f5c ("iio: adc: stm32-adc: fix a regression when using dma and irq") Signed-off-by:
