2020-12-10x86/resctrl: Fix incorrect local bandwidth when mba_sc is enabledXiaochen Shen
The MBA software controller (mba_sc) is a feedback loop which periodically reads MBM counters and tries to restrict the bandwidth below a user-specified value. It tags along the MBM counter overflow handler to do the updates with 1s interval in mbm_update() and update_mba_bw(). The purpose of mbm_update() is to periodically read the MBM counters to make sure that the hardware counter doesn't wrap around more than once between user samplings. mbm_update() calls __mon_event_count() for local bandwidth updating when mba_sc is not enabled, but calls mbm_bw_count() instead when mba_sc is enabled. __mon_event_count() will not be called for local bandwidth updating in MBM counter overflow handler, but it is still called when reading MBM local bandwidth counter file 'mbm_local_bytes', the call path is as below: rdtgroup_mondata_show() mon_event_read() mon_event_count() __mon_event_count() In __mon_event_count(), m->chunks is updated by delta chunks which is calculated from previous MSR value (m->prev_msr) and current MSR value. When mba_sc is enabled, m->chunks is also updated in mbm_update() by mistake by the delta chunks which is calculated from m->prev_bw_msr instead of m->prev_msr. But m->chunks is not used in update_mba_bw() in the mba_sc feedback loop. When reading MBM local bandwidth counter file, m->chunks was changed unexpectedly by mbm_bw_count(). As a result, the incorrect local bandwidth counter which calculated from incorrect m->chunks is shown to the user. Fix this by removing incorrect m->chunks updating in mbm_bw_count() in MBM counter overflow handler, and always calling __mon_event_count() in mbm_update() to make sure that the hardware local bandwidth counter doesn't wrap around.

2020-12-10serial: 8250_omap: Avoid FIFO corruption caused by MDR1 accessAlexander Sverdlin
It has been observed that once per 300-1300 port openings the first transmitted byte is being corrupted on AM3352 ("v" written to FIFO appeared as "e" on the wire). It only happened if single byte has been transmitted right after port open, which means, DMA is not used for this transfer and the corruption never happened afterwards. Therefore I've carefully re-read the MDR1 errata (link below), which says "when accessing the MDR1 registers that causes a dummy under-run condition that will freeze the UART in IrDA transmission. In UART mode, this may corrupt the transferred data". Strictly speaking, omap_8250_mdr1_errataset() performs a read access and if the value is the same as should be written, exits without errata-recommended FIFO reset. A brief check of the serial_omap_mdr1_errataset() from the competing omap-serial driver showed it has no read access of MDR1. After removing the read access from omap_8250_mdr1_errataset() the data corruption never happened any more.

2020-12-10usb: gadget: f_fs: Re-use SS descriptors for SuperSpeedPlusJack Pham
In many cases a function that supports SuperSpeed can very well operate in SuperSpeedPlus, if a gadget controller supports it, as the endpoint descriptors (and companion descriptors) are generally identical and can be re-used. This is true for two commonly used functions: Android's ADB and MTP. So we can simply assign the usb_function's ssp_descriptors array to point to its ss_descriptors, if available. Similarly, we need to allow an epfile's ioctl for FUNCTIONFS_ENDPOINT_DESC to correctly return the corresponding SuperSpeed endpoint descriptor in case the connected speed is SuperSpeedPlus as well. The only exception is if a function wants to implement an Isochronous endpoint capable of transferring more than 48KB per service interval when operating at greater than USB 3.1 Gen1 speed, in which case it would require an additional SuperSpeedPlus Isochronous Endpoint Companion descriptor to be returned as part of the Configuration Descriptor. Support for that would need to be separately added to the userspace-facing FunctionFS API which may not be a trivial task--likely a new descriptor format (v3?) may need to be devised to allow for separate SS and SSP descriptors to be supplied.

2020-12-10can: m_can: add PCI glue driver for Intel Elkhart LakeJarkko Nikula
Add support for M_CAN controller on Intel Elkhart Lake attached to the PCI bus. It integrates the Bosch M_CAN controller with Message RAM and the wrapper IP block with additional registers which all of them are within the same MMIO range. Currently only interrupt control register from wrapper IP is used and the MRAM configuration is expected to come from the firmware via "bosch,mram-cfg" device property and parsed by m_can.c core. Initial implementation is done by Felipe Balbi while he was working at Intel with later changes from Raymond Tan and me.

2020-12-10can: m_can: move runtime PM enable/disable to m_can_platformPatrik Flykt
This is a preparatory patch for upcoming PCI based M_CAN devices. The current PM implementation would cause PCI based drivers to enable PM twice, once when the PCI device is added and a second time in m_can_class_register(). This will cause 'Unbalanced pm_runtime_enable!' to be logged, and is a situation that should be avoided. Therefore, in anticipation of PCI devices, move PM enabling out from M_CAN class registration to its only user, the m_can_platform driver.

2020-12-10can: isotp: add SF_BROADCAST support for functional addressingOliver Hartkopp
When CAN_ISOTP_SF_BROADCAST is set in the CAN_ISOTP_OPTS flags the CAN_ISOTP socket is switched into functional addressing mode, where only single frame (SF) protocol data units can be send on the specified CAN interface and the given tp.tx_id after bind(). In opposite to normal and extended addressing this socket does not register a CAN-ID for reception which would be needed for a 1-to-1 ISOTP connection with a segmented bi-directional data transfer. Sending SFs on this socket is therefore a TX-only 'broadcast' operation.

2020-12-10zonefs: fix page reference and BIO leakDamien Le Moal
In zonefs_file_dio_append(), the pages obtained using bio_iov_iter_get_pages() are not released on completion of the REQ_OP_APPEND BIO, nor when bio_iov_iter_get_pages() fails. Furthermore, a call to bio_put() is missing when bio_iov_iter_get_pages() fails. Fix these resource leaks by adding BIO resource release code (bio_put()i and bio_release_pages()) at the end of the function after the BIO execution and add a jump to this resource cleanup code in case of bio_iov_iter_get_pages() failure. While at it, also fix the call to task_io_account_write() to be passed the correct BIO size instead of bio_iov_iter_get_pages() return value.
