The compiler is already able to eliminate the kvm_arch_get_supported_cpuid()
calls in kvm_cpu_fill_host() and filter_features_for_kvm(), so we can
eliminate the CONFIG_KVM #ifdefs there.
Also, kvm_cpu_fill_host() and host_cpuid() don't need to check
CONFIG_KVM, as they don't have any KVM-specific function calls.
Tested to build successfully with CONFIG_KVM disabled, using the
following CFLAGS combinations: "-DNDEBUG", "-DNDEBUG -O', "-DNDEBUG
-O0", "-DNDEBUG -O1", "-DNDEBUG -O2".

The MS docs specify HV_X64_MSR_HYPERCALL as a mandatory interface,
thus we must provide the MSRs even if the user only specified
features that, like relaxed timing, in principle don't require them.
And the MSRs are only there if the hypervisor has KVM_CAP_HYPERV.

kvm_arch_init_vcpu's initialization of the KVM leaves at 0x40000100

KVM introduced internal error exit reason and suberror at the same time,
and later extended it with internal error data.
QEMU does not report suberror on hosts between these two events because
we check for the extension. (half a year in 2009, but it is misleading)
Fix by removing KVM_CAP_INTERNAL_ERROR_DATA condition on printf.

There's no need to check CPU xlevel2 before calling
kvm_arch_get_supported_cpuid(s, 0xC0000001, 0, R_EDX), because:
* The kernel won't return any entry for 0xC0000000 if host CPU vendor
is not Centaur (See kvm_dev_ioctl_get_supported_cpuid() on the kernel
code)
* Similarly, the kernel won't return any entry for 0xC0000001 if
CPUID[0xC0000000].EAX is < 0xC0000001
* kvm_arch_get_supported_cpuid() will return 0 if no entry is returned
by the kernel for the requested leaf
For similar reasons, we can simply set x86_cpu_def->xlevel2 directly
instead of making it conditional, because it will be set to 0 CPU vendor
is not Centaur.
This will simplify the kvm_cpu_fill_host() code a little.

floppy: Fix incorrect LBA to CHS translation.
floppy: Fix accesses to DOR register.

floppy: Encode command and flags into single value in floppy pio code.

floppy: Implement cylinder seeking when accessing a different cylinder.
coreboot: Make sure to print the SeaBIOS version in cbmem debug output.

When using $(MAKE) within a makefile, we shouldn't be explicitly
including $(MAKEFLAGS) on the command-line. It causes problems
when that makefile is recursively invoked. When the roms/Makefile
is invoked as in make -C roms bios a spurious 'w' appears on the

__put_user can write bytes, words (2 bytes) or longwords (4 bytes).
Here obviously words should have been written, but bytes were written,
so values like 0x9c5f were truncated to 0x5f.
Fix this by changing retcode from uint8_t to to uint16_t in
target_signal_frame and also in the unused rt_signal_frame.
This problem was reported by static code analysis (smatch).

2. correct sign for requested_height

causes a complete guess blackout until reset, so it helps if it is

Currently we fail getattr request altogether if we can't read
P9_STATS_GEN for some reason. It breaks valid use cases:
E.g let's assume we have non-readable directory with execution bit set
on host and we export it to client over 9p On host we can chdir into
directory, but not open directory on read and list content.
But if client will try to call getattr (as part of chdir(2)) for the
directory it will fail with -EACCES. It happens because we try to open
the directory on read to call ioctl(FS_IOC_GETVERSION), it fails and we
return the error code to client.
It's excessive. The solution is to make P9_STATS_GEN failure non-fatal
for getattr request. Just don't set P9_STATS_GEN flag in result mask on
failure.

The 071 test is designed for IMGFMT=qcow2 because it uses the l2_load
blkdebug event. Its output filtering also assumes that IMGFMT is not
raw since 071.out contains "format=raw" but IMGFMT=raw would filter the
output to "format=IMGFMT".
Perhaps the test case can be rewritten to be more generic, but for now
let's document that it was only supposed to work with qcow2.
