Wrong vmap_block index/offset values could lead to memory corruption.
However, this has never been observed in practice (or never been

checks for inconsistent vmap_block indices.
To fix this, ensure that VMAP_BLOCK_SIZE always is a power of two.

In this code, the failure_cleanup label calls the function
plx_pci_del_card, which frees everything in the card->net_dev array. dev
is placed in this array immediately after allocation, so the two subsequent
jumps to failure_cleanup should not also call free_sja1000dev, but the
second one does.
If plx_pci_check_sja1000 fails, then free_sja1000dev is also called on
dev. Because dev is already in the card->net_dev array, this implies that
when plx_pci_del_card is later called, it may get freed again. So that
entry is reset to NULL after the free.
Finally, if there is a problem with one channel, there will be a hole in the
array. card->channels counts the number of channels that have succeeded,
and does not keep track of the index of the largest element in the array
that is valid. So the loop in plx_pci_del_card is changed to go up to
PLX_PCI_MAX_CHAN, which is only 2.

mmc: sdhci: use f_max instead of host->clock for timeouts
When timeout_clk is calculated the host->clock could be zero.
So, instead of host->clock the calculation now uses mmc->f_max.

mmc: sdhci: check host->clock before using it as a denominator
Sometimes host->clock could be zero which is a legal situation. This
patch checks host->clock before usage as a denominator when timeout is
calculated. A similar patch is applied for mmc core (see commit e9b8684,
"mmc: fix division by zero in MMC core").
Without this patch, the execution of the sdhci_calc_timeout could end up
with a backtrace:

This reverts commit 4b01681c7764, which introduced a new potential
divide by zero in the process of fixing one. The subsequent commits
attempt to fix the issue properly.
