The imx7d usdhc is derived from imx6sx, the difference is that
imx7d support HS400.

This patch was originally introduced when we made power_allocator the
default governor where we had issues in binding a thermal zone w/o
parameters to. Then we came out this facility for binding a specific
governor to a thermal zone in dts instead of the default governor.
Javi seems like this idea

kfree on NULL pointer is a no-op.
This patch uses the following semantic patch to find such an instance
where NULL check is present before kfree.
//
@@ expression E; @@
- if (E != NULL) { kfree(E); }
+ kfree(E);
@@ expression E; @@
- if (E != NULL) { kfree(E); E = NULL; }

Given that I've gotten some of the details wrong in the past (and I've
seen others do likewise), I thought it might be helpful to collate the
best practices for adding a new system call to the kernel.
Apologies for the wide circulation -- I've tried to include folk who've

The xhci platform driver needs to work on systems that
either only support 64-bit DMA or only support 32-bit DMA.
Attempt to set a coherent dma mask for 64-bit DMA, and
attempt again with 32-bit DMA if that fails.

Currently, we store class:fullness into page->mapping.
The number of class we can support is 255 and fullness is 4 so
10bit is enough to represent them.
IOW, we have room (sizeof(void *) * 8 - 10) in mapping.
Meanwhile, the bits we need to store in-use objects in zspage
is just 11bit like below.
Every zspage in a size_class has same max_objects so we could
move it to a size_class.

For supporting runtime compaction with VM, we need to have proper
address_space on every page so zsmalloc shouldn't use page->mapping.
This patch moves zsmalloc metadata from mapping to freelist.
