vm: improve memory usage under sparse with a high reserved memory ratio
...
previously, sparse would attempt to create a smaller number of larger sectors on systems with lots of reserved memory, often causing an out-of-memory condition. the reserved memory ratio calculation now compares reserved memory to free memory, rather than to the address of the last byte in physical memory. this improved heuristic means sparse is now better at choosing an appropriate sector size, allowing sparse to operate on systems with high amounts of reserved memory.

vm: fix overflow in memblock do_alloc when allocating large aligned blocks
...
allocating a large power-of-2 block with memblock may cause the base pointer of a region to exceed the limit pointer after it has been aligned during the free region scan in do_alloc().

dev: implement reading from block devices
...
reading from block devices is done using the block cache (bcache).
This cache stores sectors from a block device in pages of memory
marked as 'cached', which will allow them to be reclaimed when
memory pressure is high (TODO).
while block device drivers implement callbacks allowing reading/writing
at block-granularity, the device subsystem uses the block cache to
implement reading/writing at byte-granularity in a driver-agnostic way.
block drivers can disable the block cache for their devices, but this
will require that any clients communicate with the devices at
block-granularity.
also added an offset parameter to device and object read/write functions/callbacks.
