ARM Architecture Reference Manual says: "Setting SYST_RVR to zero has the effect of disabling the SysTick counter independently of the counter enable bit."
If Monotonic's ratio is less than one, the timeout calculations
can compute zero if next task is scheduled after current instant, but
before next timer tick. This results in disabling SYST and freezing the
timer queue.
275: fix CI r=perlindgren a=japaric
after caching was enabled binary install through the trust/install.sh script
stopped working (due to permissions?). This updates crate installation to use
`cargo-install` iff the requested version of a crate is not already installed

268: CI: replace compiletest-rs with trybuild r=japaric a=japaric
We use compiletest to run compile-fail tests but compiletest depends on compiler
internals so it breaks every now and then and requires nightly. With trybuild we
can also run compile-fail tests but it works on stable and it already has
reached version 1.0
270: Added struct de-structure-ing example in tips & tricks r=japaric a=korken89

this version is more or less fixed so new releases of Rust (stable or nightly
channel) are unlikely to break to build due to changes in diagnostic messages

266: CI: build 0.4 docs from the v0.4.x branch r=korken89 a=japaric
instead of using a specific tag; this way documentation changes done to the
v0.4.x branch will show up on the site as soon as they land -- right now they
require publishing a new v0.4.x release on crates.io

257: do not zero late resource memory on boot r=korken89 a=japaric
this is done using the `.uninit` linker section; this optimization was already
being applied to message buffers but I forgot to also apply it to late resources

255: more monotonic timer docs r=nils-grepit a=japaric
covers
- initialization and configuration of the timer; this is now a responsibility of
the application author
- correctness of `Monotonic::now()` in `#[init]`
- safety of `Monotonic::reset()`

originally the type was made `!Send` because it loses its meaning when
send from one core to another but that was an incorrect use of the `Send`
bound (the send operation makes the value incorrect but that doesn't cause
memory unsafety on its own). So later the type was (explicitly) made `Send`
again resulting in a convoluted implementation -- this commit simplifies things.

252: critical sections book: each task gets its own context r=japaric a=chrysn
Fixing what was probably a copy-paste error; different tasks each have different types for their context.

253: Fix matrix.to web link for the static room view. r=japaric a=tim-seoss
Fix the matrix.to link so that the room history can be viewed in
"Matrix-Static" by users who aren't registered on Matrix (e.g. for
previewing). Hopefully this will also get the room content into search
engines.
n.b. The new matrix.to URL uses the room name instead of the room ID,
because the ID didn't work with Matrix-Static, and the matrix.to README at:
https://github.com/matrix-org/matrix.to says...
"Note that linking to rooms by ID should only be used for rooms to which
the target user has been invited: these links cannot be assumed to work for
all visitors."

245: add CONTRIBUTING.md and link to Matrix room r=korken89 a=nils-grepit
Inspired by the Rust lang [CONTRIBUTING.md](https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md), but small. There might be more we want to use from there.
