2021-01-27platform/goldfish: Convert pipe tasklet to threaded irqDavidlohr Bueso1-17/+11
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.

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.

2021-01-27misc: pti: Remove driver for deprecated platformAndy Shevchenko9-1624/+0
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 05f4434bc130 ("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 Due to above and to reduce a burden of supporting outdated drivers we remove the support of outdated platforms completely.

2021-01-27speakup: Reference synth from tty and tty from synthSamuel Thibault2-73/+46
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: Samuel Thibault <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>

The K: entry should ensure that Nick and I always get CC'd on patches that touch these files but it is better to be explicit rather than implicit.

2021-01-24proc_sysctl: fix oops caused by incorrect command parametersXiaoming Ni1-1/+6
The process_sysctl_arg() does not check whether val is empty before invoking strlen(val). If the command line parameter () is incorrectly configured and val is empty, oops is triggered. For example: "hung_task_panic=1" is incorrectly written as "hung_task_panic", oops is triggered. The call stack is as follows: Kernel command line: .... hung_task_panic ...... Call trace: __pi_strlen+0x10/0x98 parse_args+0x278/0x344 do_sysctl_args+0x8c/0xfc kernel_init+0x5c/0xf4 ret_from_fork+0x10/0x30 To fix it, check whether "val" is empty when "phram" is a sysctl field. Error codes are returned in the failure branch, and error logs are generated by parse_args().

2021-01-24powerpc/mm/highmem: use __set_pte_at() for kmap_local()Thomas Gleixner1-0/+2
The original PowerPC highmem mapping function used __set_pte_at() to denote that the mapping is per CPU. This got lost with the conversion to the generic implementation. Override the default map function.
