DS18B20 device driver returns an incorrect value for negative temperatures due to a missing sign-extension in w1_DS18B20_convert_temp(). Fix by using s16 temperature value when converting to int.

Tasklets have long been deprecated as being too heavy on the system by running in irq context - and this is not a performance critical path. If a higher priority process wants to run, it must wait for the tasklet to finish before doing so. A more suitable equivalent is to converted to threaded irq instead and deal with the signaled pipes in task context. Signed-off-by:

Do not use wait_event_interruptible when vbg_hgcm_call() gets called from kernel-context, such as it being called by the vboxsf filesystem code.

Suggested by Paolo & Greg, add 'events' device attribute that can be used to limit which capabilities the driver uses. Finally, the pvpanic guest driver works by the limitation of both device capability and user setting. Signed-off-by:

According to pvpanic spec: https://git.qemu.org/?p=qemu.git;a=blob_plain;f=docs/specs/pvpanic.txt The guest should determine pvpanic capability by RDPT, so initialize capability during device probing. There is no need to register panic notifier callback function if no events supported. Before sending event to host side, check capability firstly. Suggested by Greg KH, use sysfs to expose capability to user space, also add new sysfs attribute in document. Signed-off-by:

Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago. There are no bugs or problems ever reported outside from Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. The commit 05f4434b ("ASoC: Intel: remove mfld_machine") also in align with this theory. Due to above and to reduce a burden of supporting outdated drivers we remove the support of outdated platforms completely. Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Acked-by:

Samuel Thibault authored
We do not actually need speakup_tty and spk_ttyio_synth global variables, the synth can store the pointer to the tty, and the tty ldisc_data can store the pointer to the synth. Along the way, we can clench the initialization of the synth and the creation of the tty, so that tty is never NULL. Even if the device disappears (e.g. USB unplug), the tty structure will still be there, and we automatically stop speakup in the spk_ttyio_out error handler but keep tty until the user cleans things up. As a result, this simplifies locking a lot. Signed-off-by:

When create the VMCI queue pair tracking data structures on the host side, the IOCTL for creating the VMCI queue pair didn't validate the queue pair size parameters. This change adds checks for this. This avoids a memory allocation issue in qp_host_alloc_queue, as reported by nslusarek@gmx.net. The check in qp_host_alloc_queue has also been updated to enforce the maximum queue pair size as defined by VMCI_MAX_GUEST_QP_MEMORY. The fix has been verified using sample code supplied by nslusarek@gmx.net. Reported-by: nslusarek@gmx.net Reviewed-by:

When the VMCI host support releases guest memory in the case where the VM was killed, the pinned guest pages aren't locked. Use set_page_dirty_lock() instead of set_page_dirty(). Testing done: Killed VM while having an active VMCI based vSocket connection and observed warning from ext4. With this fix, no warning was observed. Ran various vSocket tests without issues. Fixes: 06164d2b ("VMCI: queue pairs implementation.") Reviewed-by:

VMCI queue pair allocation is disabled, if a VM is in FT mode. In these cases, VMware Tools may still once in a while attempt to create a vSocket stream connection, resulting in multiple warnings in the kernel logs. Therefore downgrade the error log to a debug log. Reviewed-by:
