So that in the case where we have E820_RAM right above 1MB, we don't
call init_memory_mapping twice, first on 0 ~ 1MB and then 1MB ~ something
we only call it once. 0 ~ something.
So what is the benefit?

DIV_ROUND_CLOSEST returns a bad result for negative dividends:
DIV_ROUND_CLOSEST(-2, 2) = 0
Most of the time this does not matter. However, in the hardware monitoring

Current logic finds enough space for direct mapping page tables from 0
to end. Instead, we only need to find enough space to cover mr[0].start
to mr[nr_range].end -- the range that is actually being mapped by
init_memory_mapping()
This patch also reportedly fixes suspend/resume issue reported in:
Currently kernel direct mappings are created for all pfns between
[ 0 to max_low_pfn ) and [ 4GB to max_pfn ). When we introduce memory
holes, we end up mapping memory ranges that are not backed by physical
DRAM. This is fine for lower memory addresses which can be marked as UC
by fixed/variable
There could be cases where user supplied memmap=exactmap memory
mappings do not mark the region where the kernel .text .data and
.bss reside as E820_RAM as reported here:
https://lkml.org/lkml/2012/8/14/86
Handle it by complaining, and adding the range back into the e820.

In drivers/gpu/drm/Kconfig "config DRM_USB" depends on USB_ARCH_HAS_HCD

Some of our language runtimes like to map IP addresses in perf backtrace
to specific byte codes. The way things stand now, the addresses on the
backtrace are return addresses, rather than the caller. I think this

I have applied this to tip:x86/fpu, but I have also asked Suresh to
prepare a followon patch to decouple eager save from the existence of
the XSAVE instruction. It seems pretty clear that eager save is a net
benefit in the presence of the XSAVEOPT, but it isn't as clear for only
having XSAVE, as

No need to save the state with unlazy_fpu(), that is about to get overwritten
by the state from the signal frame. Instead use drop_fpu() and continue
to restore the new state.
Also fold the stop_fpu_preload() into drop_fpu().

kvm's guest fpu save/restore should be wrapped around
kernel_fpu_begin/end(). This will avoid for example taking a DNA
in kvm_load_guest_fpu() when it tries to load the fpu immediately
after doing unlazy_fpu() on the host side.
More importantly this will prevent the host process fpu from being
use kernel_fpu_begin/end() instead of unconditionally accessing cr0 and
saving/restoring just the few used xmm/ymm registers.
This has some advantages like:
* If the task's FPU state is already active, then kernel_fpu_begin()
will just save the user-state and avoiding the read/write of cr0.
Fundamental model of the current Linux kernel is to lazily init and
restore FPU instead of restoring the task state during context switch.
This changes that fundamental lazy model to the non-lazy model for
the processors supporting xsave feature.
Reasons driving this model change are:
i. Newer
Instead of using unlazy_fpu() check if user_has_fpu() and set/clear
the host TS bits so that the lguest works fine with both the
lazy/non-lazy FPU host models with minimal changes.
