Alex Bennée bf0c50d4aa monitor: expose monitor_puts to rest of code
This helps us construct strings elsewhere before echoing to the
monitor. It avoids having to jump through hoops like:

  monitor_printf(mon, "%s", s->str);

It will be useful in following patches but for now convert all
existing plain "%s" printfs to use the _puts api.

Richard Henderson b21af662c1 accel/tcg: Use DisasContextBase in plugin_gen_tb_start
Use the pc coming from db->pc_first rather than the TB.

Use the cached host_addr rather than re-computing for the
first page.  We still need a separate lookup for the second
page because it won't be computed for DisasContextBase until
the translator actually performs a read from the page.

The class cast checkers are quite expensive and always on (unlike the
dynamic case who's checks are gated by CONFIG_QOM_CAST_DEBUG). To
avoid the overhead of repeatedly checking something which should never
change we cache the CPUClass reference for use in the hot code paths.

Lev KujawskiandKevin Wolf 176e4961bb hw/ide/core.c: Implement ATA INITIALIZE_DEVICE_PARAMETERS command
CHS-based disk utilities and operating systems may adjust the logical
geometry of a hard drive to cope with the expectations or limitations
of software using the ATA INITIALIZE_DEVICE_PARAMETERS command.

Prior to this patch, INITIALIZE_DEVICE_PARAMETERS was a nop that
always returned success, raising the possibility of data loss or
corruption if the CHS<->LBA translation redirected a write to the
wrong sector.

* hw/ide/core.c
ide_reset():
  Reset the logical CHS geometry of the hard disk when the power-on
  defaults feature is enabled.
cmd_specify():
  a) New function implementing INITIALIZE_DEVICE_PARAMETERS.
  b) Ignore calls for empty or ATAPI devices.
cmd_set_features():
  Implement the power-on defaults enable and disable features.
struct ide_cmd_table:
  Switch WIN_SPECIFY from cmd_nop() to cmd_specify().
ide_init_drive():
  Set new fields 'drive_heads' and 'drive_sectors' based upon the
  actual disk geometry.

* include/hw/ide/internal.h
struct IDEState:
a) Store the actual drive CHS values within the new fields
   'drive_heads' and 'drive_sectors.'
b) Track whether a soft IDE reset should also reset the logical CHS
   geometry of the hard disk within the new field 'reset_reverts'.

function to there and make it static.

Denis V. LunevandKevin Wolf 62a6c300f1 block: add missed block_acct_setup with new block device init procedure
Commit 5f76a7aac1 is looking harmless from
the first glance, but it has changed things a lot. 'libvirt' uses it to
detect that it should follow new initialization way and this changes
things considerably. With this procedure followed, blockdev_init() is
not called anymore and thus block_acct_setup() helper is not called.

This means in particular that defaults for block accounting statistics
are changed and account_invalid/account_failed are actually initialized
as false instead of true originally.

This commit changes things to match original world. There are the following
constraints:
* new default value in block_acct_init() is set to true
* block_acct_setup() inside blockdev_init() is called before
  blkconf_apply_backend_options()
* thus newly created option in block device properties has precedence if
  specified
