the block_size header field has a reasonable value. Also enforce the

qtest test cases only work on POSIX hosts. The following line only
defines dependencies for qtest binaries on POSIX hosts:
check-qtest-$(CONFIG_POSIX)=$(foreach TARGET,$(TARGETS),$(check-qtest-$(TARGET)-y))
But the QTEST_TARGETS definition earlier in the Makefile fails to check
CONFIG_POSIX. This causes make targets to be generated for qtest test
cases even though we don't know how to build the binaries.
The following error message is printed when trying to run gtester on a
binary that was never built:
GLib-WARNING **: Failed to execute test binary: tests/endianness-test.exe: Failed to execute child process "tests/endianness-test.exe" (No such file or directory)
This patch makes QTEST_TARGETS empty on non-POSIX hosts. This prevents
the targets from being generated.

CPU address spaces touching load and store helpers as well as the
movement of (almost) all fields from CPU_COMMON to CPUState have led to
a noticeable increase of CPU() usage in "hot" paths for both TCG and KVM.
While CPU()'s OBJECT_CHECK() might help detect development errors, i.e.
in form of crashes due to QOM vs. non-QOM mismatches rather than QOM
type mismatches, it is not really needed at runtime since mostly used in
CPU-specific paths, coming from a target-specific CPU subtype. If that
pointer is damaged, other errors are highly likely to occur elsewhere
anyway.
Keep the CPU() macro for a consistent developer experience and for
flexibility to exchange its implementation, but turn it into a pure,
unchecked C cast for now.

Linux guests, when using more than 4GB of RAM, may end up using 1GB pages
to store (kernel) data. When this happens, we're unable to debug a running
Linux kernel with GDB:
(gdb) p node_data[0]->node_id
Cannot access memory at address 0xffff88013fffd3a0
(gdb)
GDB returns this error because x86_cpu_get_phys_page_debug() doesn't support
translating 1GB pages in IA-32e paging mode and returns an error to GDB.
This commit adds support for 1GB page translation for IA32e paging.

A HPET timer can be started when HPET is not yet
enabled. This will not generate an interrupt
to the guest, but causes problems when HPET is later
enabled.
A timer that is created and expires at least once before
HPET is enabled will have an initialized comparator based
on a hpet_offset of 0 (uninitialized). When HPET is
enabled, hpet_set_timer() is called a second time, which
modifies the timer expiry to a time based on the
difference between current ticks (measured with the
newly initialized hpet_offset) and the timer's
comparator (which was generated before hpet_offset was
initialized). This results in a long period of no HPET
timer ticks.
When this occurs with a CentOS 5.x guest, the guest
may not receive timer interrupts during its narrow
timer check window and panic on boot.
