Transactions not acked can happen every now and then, in particular during device detection, and various transaction types can be used for this purpose. So stop logging this event, except when debugging is enabled. This is what other similar drivers (e.g. i2c-i801 or i2c-piix4) do. Signed-off-by:Jean Delvare <khali@linux-fr.org>

The underlying I2C adapter may or may not be present when this driver gets initialized, and may disappear later, so there is no safe time at which the probe and remove functions can be discarded. Signed-off-by:

The functions the functions amd_ec_wait_write and amd_ec_wait_read have an unsigned return type, but return a negative constant to indicate an error condition. A sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ identifier f; constant C; @@ unsigned f(...) { <+... * return -C; ...+> } // </smpl> Fixing amd_ec_wait_write and amd_ec_wait_read leads to the need to adjust the return type of the functions amd_ec_write and amd_ec_read, which are the only functions that call amd_ec_wait_write and amd_ec_wait_read. amd_ec_write and amd_ec_read, in turn, are only called from within the function amd8111_access, which already returns a signed typed value. Each of the calls to amd_ec_write and amd_ec_read are updated using the following semantic patch: // <smpl> @@ @@ + status = amd_ec_write - amd_ec_write (...); + if (status) return status; @@ @@ + status = amd_ec_read - amd_ec_read (...); + if (status) return status; // </smpl> The patch also adds the declaration of the status variable.

drivers/i2c/algos/Kconfig makes all the algorithms dependent on !I2C_HELPER_AUTO, which triggers a Kconfig warning about broken dependencies when some driver selects one of the algorithms. Ideally we would make only the prompts dependent on !I2C_HELPER_AUTO, however Kconfig doesn't currently support that. So we have to redefine the symbols separately for the I2C_HELPER_AUTO=y case.

Originally, SRAR SIGBUS is sent to QEMU-KVM via touching the poisoned page. But commit 96054569 prevents the signal from being sent. So now the signal is sent via force_sig_info_fault directly. [marcelo: use send_sig_info instead] Reported-by:

Negate the effects of AN TYM spell while kvm thread is preempted by tracking conversion factor to the highest TSC rate and catching the TSC up when it has fallen behind the kernel view of time. Note that once triggered, we don't turn off catchup mode. A slightly more clever version of this is possible, which only does catchup when TSC rate drops, and which specifically targets only CPUs with broken TSC, but since these all are considered unstable_tsc(), this patch covers all necessary cases.

The math in kvm_get_time_scale relies on the fact that NSEC_PER_SEC < 2^32. To use the same function to compute arbitrary time scales, we must extend the first reduction step to shrink the base rate to a 32-bit value, and possibly reduce the scaled rate into a 32-bit as well. Note we must take care to avoid an arithmetic overflow when scaling up the tps32 value (this could not happen with the fixed scaled value of NSEC_PER_SEC, but can happen with scaled rates above 2^31.
