Change the condition statement to also check the max_discard value in order
to avoid an unnecessary call to mmc_do_calc_max_discard.

Hi Kirill,Mi
DML uses the compiler option -mpreferred-stack-boundary=4 to configure
a stack alignment of 16 bytes. Clang uses the option -mstack-alignment
instead, which expects as parameter the alignment in bytes, and not a
power of two like -mpreferred-stack-boundary.
Probe for both compiler options and use
Use subdir-ccflags instead of specifying the same flags for every source
file.

It's something looks weird that those files could be written by root
but shows with no write permission by ll command.
Chen LinX has sent a similar patch to fix
graph function file mode in 2000, I didn't get the reason why that
patch wasn't applied so I resend it.

Most callers of put_cmsg() use a "sizeof(foo)" for the length argument.
Within put_cmsg(), a copy_to_user() call is made with a dynamic size, as a

Kirill and I were talking about trying to overflow page->_mapcount
the other day and realised that the default settings of pid_max and
max_map_count prevent it [1]. But there isn't even documentation to
warn a sysadmin that they've just opened themselves up to the possibility
that they've opened

This adds documentation for the new reset-on-suspend property. This
property enables saving and restoring the ITS for when it loses state
in system suspend.

A lot of changes in v2. The distributor and redistributor saving and
restoring is left to the PSCI/firmware implementation after
discussions with ARM. This reduces the line changes by a lot and
removes now unneeded patches.
Patches are verified on an RK3399 platform with pending patches in the

This adds functionality to resend the MAPC command to an ITS node on
resume. If the ITS is powered down during suspend and the collections
are not backed by memory, the ITS will lose that state. This just sets
up the known state for the collections after the ITS is restored.
This is enabled via th
Some platforms power off GIC logic in suspend, so we need to
save/restore state. The distributor and redistributor registers need
to be handled in platform code due to access permissions on those
registers, but the ITS registers can be restored in the kernel.
