[PATCH 1/6] KVM: Fix some wrong function names in comment

[linmiaohe]

From: Miaohe Lin <linmiaohe@huawei.com>

Fix some wrong function names in comment. mmu_check_roots is a typo for
mmu_check_root, vmcs_read_any should be vmcs12_read_any and so on.

[PATCH 2/6] KVM: Fix some out-dated function names in comment

[linmiaohe]

From: Miaohe Lin <linmiaohe@huawei.com>

Since commit b1346ab2afbe ("KVM: nVMX: Rename prepare_vmcs02_*_full to
prepare_vmcs02_*_rare"), prepare_vmcs02_full has been renamed to
prepare_vmcs02_rare.
nested_vmx_merge_msr_bitmap is renamed to nested_vmx_prepare_msr_bitmap
since commit c992384bde84 ("KVM: vmx: speed up MSR bitmap merge").

I'd whack "the" instead of "and", i.e. ...walk page tables of an L2 guest,
as KVM isn't limited to just one L2 guest.

While you're here, want to change "l2" to "L2"?

This should remove "can" instead of "are", i.e. ...part that runs if we are
in atomic context.  The comment is calling out that hva_to_pfn() will return
immediately if hva_to_pfn_fast() and the kernel is atomic context.

Regarding the patch organizing, I'd probably group the comment changes
based on what files they touch as opposed to what type of comment issue
they're fixing.

E.g. three patches for the comments

   KVM: VMX: Fix comment blah blah blah
   KVM: x86: Fix comment blah blah blah
   KVM: Fix comment blah blah blah

and one patch for the print typo in hyperv

   KVM: hyperv: Fix some typos in vcpu unimpl info

For KVM, the splits don't matter _that_ much since they more or less all
get routed through the maintainers/reviewers, but it is nice when patches
can be contained to specific subsystems/areas as it allows people to easily
skip over patches that aren't relevant to them.

Many thanks for your advice and patient explanation. I feel sorry for my poor patch organizing.
I would reorganize my patches. Thanks again.

Could you please use the "In-Reply-To" tag when you reply a mail next 
time? Otherwise every replying mail from you is listed as a separate 
one, but not folded into the initial thread in my mail client.
