them again during qemu_ld/st, either explicitly via a separate

In sdhci_sysbus_realize() we override the initialization of
s->iomem that sdhci_common_realize() performs. However we
don't destroy the old memory region before reinitializing
it, which means that the memory allocated for mr->name in
memory_region_do_init() is leaked.
Since sdhci_initfn() already initializes s->io_ops to
&sdhci_mmio_ops, always use that in sdhci_common_realize()
and remove the now-unnecessary reinitialization of the
MMIO region from sdhci_sysbus_realize().

When we add a new entry to the ARMCPRegInfo hash table in
add_cpreg_to_hashtable(), we allocate memory for tehe
ARMCPRegInfo struct itself, and we also g_strdup() the
name string. So the hashtable's value destructor function
must free the name string as well as the struct.
Spotted by clang's leak sanitizer. The leak here is a
small one-off leak at startup, because we don't support
CPU hotplug, and so the only time when we destroy
hash table entries is for the case where ARM_CP_OVERRIDE
means we register a wildcard entry and then override it later.

The load_image() function is deprecated, as it does not let the
caller specify how large the buffer to read the file into is.
Instead use load_image_size().
While we are converting this code, add an error-check
for read failure.

Currently the load_elf function in elf_ops.h uses
cpu_physical_memory_write() to write the ELF file to
memory if it is not handling it as a ROM blob. This
means we ignore the AddressSpace that the function
is passed to define where it should be loaded.
Use address_space_write() instead.

Currently monitor.c reads physical memory using
cpu_physical_memory_read(). This effectively hard-codes
assuming that all CPUs have the same view of physical
memory. Switch to address_space_read() instead, which
lets us use the AddressSpace for the CPU we're
reading memory for (falling back to address_space_memory
if there is no CPU, as happens with the "none" board).
As a bonus, this allows us to detect failures to read memory.

The API of cpu_physical_memory_write_rom() is odd, because it
takes an AddressSpace, unlike all the other cpu_physical_memory_*
access functions. Rename it to address_space_write_rom(), and
bring its API into line with address_space_write().

We now require Linux-kernel-style multiline comments:
/*
* line one
* line two
*/
Enforce this in checkpatch.pl, by backporting the relevant
parts of the Linux kernel's checkpatch.pl. (The only changes
needed are that Linux's checkpatch.pl WARN() function takes
an extra argument that ours does not, and the kernel has a
special case for networking code we don't want.)"
The kernel's checkpatch does not enforce "leading /* on
a line of its own, so that part is unique to QEMU's checkpatch.
Sample warning output:
WARNING: Block comments use a leading /* on a separate line

Marking a function coroutine_fn currently has no effect on the compiler,
but it documents that this function must be called from coroutine
context and it may yield. This is important information for the
programmer.
Also, if we ever transition to a stackless coroutine implementation,
then it's likely that the annotation will become mandatory so the
compiler can use the correct calling convention for coroutine functions.
