Some processes dont't want to be killed early, but in "Action Required"
case, those also may be killed by BUS_MCEERR_AO when sharing memory
with other which is accessing the fail memory.
And sending SIGBUS with BUS_MCEERR_AO for action required error is
strange, so ignore the non-current processes

Guest kernel reports a fixed cpu frequency in /proc/cpuinfo,
this is confused to user when turbo is enable, and aperf/mperf
can be used to show current cpu frequency after 7d5905dc14a
"(x86 / CPU: Always show current CPU frequency in /proc/cpuinfo)"
so guest should support aperf/mperf capability
I've recently (since 5.7-rc1) started noticing very rare hangs

They have been particularly difficult to debug, as the system

system is alive as I'll occaionally see firmware loading timeout

The value adapter->rss_conf is stored in DMA memory, and it is assigned
to rssConf, so rssConf->indTableSize can be modified at anytime by
malicious hardware. Because rssConf->indTableSize is assigned to n,
buffer overflow may occur when the code "rssConf->indTable[n]" is
executed.
To fix this
The value hdev->sfr.kva is stored in DMA memory, and it is assigned to
sfr, so sfr->buf_size can be modified at anytime by malicious hardware.
In this case, a buffer overflow may happen when the code
"sfr->data[sfr->buf_size - 1]" is executed.
To fix this possible bug, sfr->buf_size is assigned

Macro 'for_each_active_policy()' is defined internally. To avoid some
cpufreq driver needing this macro to iterate over all the policies in
'.set_boost' callback, we redefine '.set_boost' to act on only one
policy and pass the policy as an argument.

A test module to make sure get_count_order/long returns the correct result.

Please remove all of the __packed attributes.
I looked at your data structures and all of them use fixed sized types
and are multiples of 4 so the __packed attribute is completely
unnecessary.
The alignment attribute is also unnecessary so please remove that too.

Oh... And the cc list looks a bit odd.
You cc'd fsdevel, but none of the patches were really to any

That looked fine to me, btw. Looks like an improvement even outside
the "avoid __get_user()" and double STAC/CLAC issue.

I'm not doubting that this is a correct transformation and an
improvement, but why is it using

This code was using get_user_pages*(), in approximately a "Case 5"
scenario (accessing the data within a page), using the categorization
from [1]. That means that it's time to convert the get_user_pages*() +
put_page() calls to pin_user_pages*() + unpin_user_pages() calls.
There is some helpful
There are four cases listed in pin_user_pages.rst. These are
intended to help developers figure out whether to use
get_user_pages*(), or pin_user_pages*(). However, the four cases
do not cover all the situations. For example, drivers/vhost/vhost.c
has a "pin, write to page, set page dirty, unpin"
Hi,
It recently became clear to me that there are some get_user_pages*()
callers that don't fit neatly into any of the four cases that are so
far listed in pin_user_pages.rst. vhost.c is one of those.
Add a Case 5 to the documentation, and refer to that when converting
vhost.c.
Thanks to Jan

no need for building a native struct on kernel stack, copying
it to userland one, then calling hpsa_ioctl() which copies it
back into _another_ instance of the same struct.
