Hi Tom,
Hi all,
this series adds support for the Lattice MachXO2 FPGA chip, programmed
over slave SPI.
Tested on a raspberry pi3, beaglebone black (little endian mode) and imx6
hummingboard (big endian mode) + bugblat's pif2 fpga hat (machxo2 7000HC) or
tinyfpga A1/A2 (machxo2 256HC / 1200HC), in SPI slav
This patch adds support to the FPGA manager for programming
MachXO2 device’s internal flash memory, via slave SPI.

Hi David,
I don't see how it breaks UAPI. The point is that structures
coredump_proc_event and exit_proc_event are members of *union*
event_data, thus position of the existing data in the structure is
unchanged. Furthermore, this change won't increase size of struct
proc_event, because comm_proc_e

I only seem to have patches 1 and 2 here (and they aren't threaded with
each other which is a bit odd too). I seem to recall this has been
happening
This patch introduces a mdev (mediated device) based hardware
vhost backend. This backend is an abstraction of the various
hardware vhost accelerators (potentially any device that uses
virtio ring can be used as a vhost accelerator). Some generic
mdev parent ops are provided for accelerator drivers

I am able to workaround this issue by marking the mount as unbinadable
and clearing the flag (CL_COPY_UNBINDABLE) in "copy_tree" function in
fs/namespace.c. This skips the unbindable mounts to get cloned inside
the new namespace. For my use-case this is acceptable.

Hi Viresh,
Please find the updated series replacing the previous patch [1] fixing
couple of issues in the TI CPUFreq driver. I have split up the patches
as per your comments on v1. Final code diff remains the same as before.

The ti_cpufreq_probe() function uses regular kzalloc to allocate
the ti_cpufreq_data structure and kfree for freeing this memory
on failures. Simplify this code by using the devres managed
API.

Commit 05829d9431df ("cpufreq: ti-cpufreq: kfree opp_data when
failure") has fixed a memory leak in the failure path, however
the patch returned a positive value on get_cpu_device() failure
instead of the previous negative value. Fix this incorrect error
return value properly.

In case of error, we must undo the previous 'sca3000_configure_ring()' call
in order to free some memory.

'sca3000_configure_ring()' can fail, so test its return value and
propagate it if needed.

Un-tested and not 100% sure that we should bail-out if it fails.

It would be even better if this approach could also use
kmem_cache_free_bulk()
or
kfree_bulk()

A PTE is constructed from a physical address and a pgprotval_t.
__PAGE_KERNEL, for instance, is a pgprot_t and must be converted
into a pgprotval_t before it can be used to create a PTE. This is
done implicitly within functions like pfn_pte() by massage_pgprot().
However, thi

The entry/exit text and cpu_entry_area are mapped into userspace and
the kernel. But, they are not _PAGE_GLOBAL. This creates unnecessary
TLB misses.
Add the _PAGE_GLOBAL flag for these areas.

Summary:
In current kernels, with PTI enabled, no pages are marked Global. This
potentially increases TLB misses. But, the mechanism by which the Global
bit is set and cleared is rather haphazard. This patch makes the process
more explicit. In the end, it leaves us with Glo
Note: This has changed since the last version. It now clones the
kernel text PMDs at a much later point and also disables this
functionality on AMD K8 processors. Details in the patch.
