2020-11-06null_blk: Fix scheduling in atomic with zoned modeDamien Le Moal2-17/+32
Commit aa1c09cb65e2 ("null_blk: Fix locking in zoned mode") changed zone locking to using the potentially sleeping wait_on_bit_io() function. This is acceptable when memory backing is enabled as the device queue is in that case marked as blocking, but this triggers a scheduling while in atomic context with memory backing disabled. Fix this by relying solely on the device zone spinlock for zone information protection without temporarily releasing this lock around null_process_cmd() execution in null_zone_write(). This is OK to do since when memory backing is disabled, command processing does not block and the memory backing lock nullb->lock is unused. This solution avoids the overhead of having to mark a zoned null_blk device queue as blocking when memory backing is unused. This patch also adds comments to the zone locking code to explain the unusual locking scheme.

This was due to the following kmemdup() in tpm_read_log_efi(): int tpm_read_log_efi(struct tpm_chip *chip) { ... /* malloc EventLog space */ log->bios_event_log = kmemdup(log_tbl->log, log_size, GFP_KERNEL); if (!log->bios_event_log) { ret = -ENOMEM; goto out; } ... } When log_size is zero, due to an empty event log from firmware, ZERO_SIZE_PTR is returned from kmemdup(). Upon a read of the binary_bios_measurements file, the tpm2_bios_measurements_start() function does not perform a ZERO_OR_NULL_PTR() check on the bios_event_log pointer before dereferencing it. Rather than add a ZERO_OR_NULL_PTR() check in functions that make use of the bios_event_log pointer, simply avoid creating the binary_bios_measurements_file as is done in other event log retrieval backends. Explicitly ignore all of the events in the final event log when the main event log is empty. The list of events in the final event log cannot be accurately parsed without referring to the first event in the main event log (the event log header) so the final event log is useless in such a situation.

2020-11-06tpm_tis: Disable interrupts on ThinkPad T490sJerry Snitselaar1-2/+27
There is a misconfiguration in the bios of the gpio pin used for the interrupt in the T490s. When interrupts are enabled in the tpm_tis driver code this results in an interrupt storm. This was initially reported when we attempted to enable the interrupt code in the tpm_tis driver, which previously wasn't setting a flag to enable it. Due to the reports of the interrupt storm that code was reverted and we went back to polling instead of using interrupts. Now that we know the T490s problem is a firmware issue, add code to check if the system is a T490s and disable interrupts if that is the case. This will allow us to enable interrupts for everyone else. If the user has a fixed bios they can force the enabling of interrupts with tpm_tis.interrupts=1 on the kernel command line.

It means in a write-request I2C_SLAVE_WRITE_REQUESTED should be reported before any I2C_SLAVE_WRITE_RECEIVED. By the way, I2C_SLAVE_STOP didn't be reported in the above case because DW_IC_INTR_STAT was not 0x200. dev->status can be used to record the current state, especially Designware I2C controller has no interrupts to identify a write-request. This patch makes not only I2C_SLAVE_WRITE_REQUESTED been reported first when IC_INTR_RX_FULL is rising and dev->status isn't STATUS_WRITE_IN_PROGRESS but also I2C_SLAVE_STOP been reported when a STOP condition is received.

2020-11-06i2c: mlxbf: Remove unecessary wrapper functionsKhalil Blaiech1-111/+72
Few wrapper functions are useless and can be inlined. So delete mlxbf_i2c_read() and mlxbf_i2c_write() and replace them with readl() and writel(), respectively. Also delete mlxbf_i2c_read_data() and mlxbf_i2c_write() and replace them with ioread32be() and iowrite32be(), respectively.

2020-11-06drm/vc4: replace idr_init() by idr_init_base()Deepak R Varma1-1/+1
idr_init() uses base 0 which is an invalid identifier for this driver. The idr_alloc for this driver uses VC4_PERFMONID_MIN as start value for ID range and it is #defined to 1. The new function idr_init_base allows IDR to set the ID lookup from base 1. This avoids all lookups that otherwise starts from 0 since 0 is always unused / available.

2020-11-06drm/<drivers>: Constify struct drm_driverDaniel Vetter63-78/+75
Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const.

This means some very few #ifdef in code, but it allows us to enlist the compiler to make sure this stuff isn't used anymore. More important, only legacy drivers change drm_device (for the legacy_dev_list shadow attach management), therefore this is prep to allow modern drivers to have a const driver struct.
