In flush_nat_entries, all dirty nats will be flushed and if their new address
isn't NULL_ADDR, their bitmaps will be updated, the free_nid_count of the
bitmaps will be increased regardless of whether the nats have already been
occupied before. This could lead to wrong free_nid_count.

Currently, during __bitmap_weight() calculation hweight_long() is used.
Inside a hweight_long() a check has been made to figure out whether a
hweight32() or hweight64() version to use.

inside the loop. We can detect whethe

The instructions STR and SLDT are not emulated in any case. Thus, it made
sense to not implement functionality to identify them. However, a
subsequent commit will introduce functionality to warn about the use of
all the instructions that UMIP protect, not only those that are emulated.
A first step
Issue a rate-limited warning whenever any of the instructions that UMIP
protects (i.e., SGDT, SIDT, SLDT, STR and SMSW) are used by user space
programs.
This is useful because, with UMIP enabled, the few programs that use such
instructions will start receiving a SIGSEGV signal. In the specific cas

There are many instructions, esp on powerpc, whose mnemonics are
longer than 6 characters. Using precision limit causes truncation
of such mnemonics.
Fix this by removing precision limit. Note that, 'width' is still
6, so alignment won't get affected for length <= 6.

Hi Rafael,
I'll answer some of it from my perspective, though Jeffy might have had
different ideas (and answers) when he implemented this.
