If the tpm_transmit call in tpm_common_write fails for any reason, there is
no response that could be read. Therefore, do not require the application
to issue a read call before sending further commands. This restores the
behavior from before support for partial reads was introduced.

The recently merged API for ensuring break-before-make on page-table
entries when installing huge mappings in the vmalloc/ioremap region is
fairly counter-intuitive, resulting in the arch freeing functions
(e.g. pmd_free_pte_page()) being called even on entries that aren't
present. This resulted in

The current ioremap() code uses a phys_addr variable at each level of

In the process of handling a guest overflow, KVM unconditionally
reprograms perf counters before entering guest. The reprogramming brings
very high overhead. For common case, (e.g. vCPU still runs on the same
CPU), it's unnecessary.
Here is current process of handling an overflow

Hi,
Per acme's request, this is a rebase (and basically rewrite) of v1.
The following optimizes the rb_first() lookups in perf tooling such that we
can avoid walking down the tree finding the first element. Tree traversals
(and overall computing the first node in the tree) is a surprisingly commo

There have been a number of changes in the kernel's rbrtee
implementation, including loose lockless searching guarantees
and rb_root_cached, which later patches will use as an

Ensure that timing values for the child node are applied to
all chip selects in the child's address ranges.
Note that this does not support multiple timing settings per
child; this can be added in the future if required.
Example:
&weim {

Support multiple address ranges per child node on imx-weim.
While we're at it, insert some code which guards against common config
conflicts.

v2:

Sven Van Asbroeck (3):
bus: imx-weim: support multipl
The imx-weim driver was patched to allow correct WEIM configuration
when multiple address ranges are used in a child node.
Update the dt-bindings to reflect this.

When specifying weim child devices, there is a risk that more than
one timing setting is specified for the same chip select.
The driver cannot support such a configuration.
In case of conflict, this patch will print a warning to the log,
and will ignore the child node in question.
