a575cbe01c target/m68k: Convert to DisasContextBase
Removed ctx->insn_pc in favour of ctx->base.pc_next.
Yes, it is annoying, but didn't want to waste its 4 bytes.

4106f26e95 target/m68k: Rename DISAS_UPDATE and gen_lookup_tb
The name gen_lookup_tb is at odds with tcg_gen_lookup_and_goto_tb.
For these cases, we do indeed want to exit back to the main loop.
Similarly, DISAS_UPDATE performs no actual update, whereas DISAS_EXIT
does what it says.

d1b322182b sdcard: Disable SEND_IF_COND (CMD8) for Spec v1
CMD8 is "Reserved" in Spec v1.10.

Spec v2.00 introduces the SEND_IF_COND command:

  6.4.1 Power Up

    CMD8 is newly added in the Physical Layer Specification Version
    2.00 to support multiple voltage ranges and used to check whether
    the card supports supplied voltage. The version 2.00 or later host
    shall issue CMD8 and verify voltage before card initialization.
    The host that does not support CMD8 shall supply high voltage range.

9e1245795f sdcard: Update the Configuration Register (SCR) to Spec Version 1.10
The initial implementation is based on the Specs v1.10 (see a1bb27b1e9).

However the SCR is anouncing the card being v1.01.

The new chapters added in version 1.10 are:

    4.3.10 Switch function command

    Switch function command (CMD6) 1 is used to switch or expand
    memory card functions. [...]
    This is a new feature, introduced in SD physical Layer
    Specification Version 1.10. Therefore, cards that are
    compatible with earlier versions of the spec do not support
    it. The host shall check the "SD_SPEC" field in the SCR
    register to recognize what version of the spec the card
    complies with before using CMD6. It is mandatory for SD
    memory card of Ver1.10 to support CMD6.

    4.3.11 High-Speed mode (25MB/sec interface speed)

    Though the Rev 1.01 SD memory card supports up to 12.5MB/sec
    interface speed, the speed of 25MB/sec is necessary to support
    increasing performance needs of the host and because of memory
    size which continues to grow.
    To achieve 25MB/sec interface speed, clock rate is increased to
    50MHz and CLK/CMD/DAT signal timing and circuit conditions are
    reconsidered and changed from Physical Layer Specification
    Version 1.01.

    4.3.12 Command system (This chapter is newly added in version 1.10)

    SD commands CMD34-37, CMD50, CMD57 are reserved for SD command
    system expansion via the switch command.
    [These commands] will be considered as illegal commands (as
    defined in revision 1.01 of the SD physical layer specification).

The SWITCH_FUNCTION is implemented since the first commit, a1bb27b1e9.

The 25MB/sec High-Speed mode was already updated in d7ecb86752.

The current implementation does not implements CMD34-37, CMD50 and
CMD57, thus these commands already return ILLEGAL.

With this patch, the SCR register now matches the description of the header:

 * SD Memory Card emulation as defined in the "SD Memory Card Physical
 * layer specification, Version 1.10."

This is an helper routine to add a single EEPROM on an I2C bus. It can
be directly used by smbus_eeprom_init() which adds a certain number of
EEPROMs on mips and x86 machines.

6c4567c730 aspeed: add an I2C RTC device to all machines
The AST2500 EVB does not have an RTC but we can pretend that one is
plugged on the I2C bus header.

The romulus and witherspoon boards expects an Epson RX8900 I2C RTC but
a ds1338 is good enough for the basic features we need.

910e204841 arm_gicv3_kvm: kvm_dist_get/put: skip the registers banked by GICR
While we skip the GIC_INTERNAL irqs, we don't change the register offset
accordingly. This will overlap the GICR registers value and leave the
last GIC_INTERNAL irq's registers out of update.

Fix this by skipping the registers banked by GICR.

Also for migration compatibility if the migration source (old version
qemu) doesn't send gicd_no_migration_shift_bug = 1 to destination, then
we shift the data of PPI to get the right data for SPI.

aca6897fba 9p: xattr: Properly translate xattrcreate flags
As with unlinkat, these flags come from the client and need to
be translated to their host values. The protocol values happen

67e8734574 9p: Properly check/translate flags in unlinkat
The 9p-local code previously relied on P9_DOTL_AT_REMOVEDIR and AT_REMOVEDIR
having the same numerical value and deferred any errorchecking to the
syscall itself. However, while the former assumption is true on Linux,
it is not true in general. 9p-handle did this properly however. Move
the translation code to the generic 9p server code and add an error
if unrecognized flags are passed.

a647502c58 9p: xattr: Fix crashes due to free of uninitialized value
If the size returned from llistxattr/lgetxattr is 0, we skipped
the malloc call, leaving xattr.value uninitialized. However, this
value is later passed to `g_free` without any further checks,
causing an error. Fix that by always calling g_malloc unconditionally.
If `size` is 0, it will return NULL, which is safe to pass to g_free.
