Fix trivial typo. No need to bump date.

Add kmem_tmpbuf_alloc(), a utility function for allocating memory for
temporary use where allocation on the stack is desirable, but only up to
a certain size.  If the requested size fits within the specified stack
buffer, the stack buffer is returned.  Otherwise, memory is allocated with
kmem_alloc().  Add a corresponding kmem_tmpbuf_free() function that frees
the memory using kmem_free() if it is not the tempory stack buffer location.

Remove trailing whitespace.

Document kmem_strdup() and kmem_strndup()

Added in 2018 by christos@ in sys/sys/kmem.h r. 1.11.

fix vmem_alloc() to never return an error for VM_SLEEP requests,
thus fixing kmem_alloc() to never return NULL for KM_SLEEP requests.
instead these operations will retry forever, which was the intent.

Drop stray .El.

Remove workaround for ancient HTML generation code.

Whitespace nit.

Spell out that KM_SLEEP allocations can fail.

Use more Dv.

New sentence, new line.

Document KMEM_SIZE, KMEM_REDZONE and KMEM_GUARD.

Rebase to HEAD as of a few days ago.

this commit was splitted into small chunks to avoid

Mention kmem_intr(9) routines.

Catchup with rmind-uvmplock merge.

CONSIDERATION => CONSIDERATIONS, to be on par with the rest of man pages.

Remove boilerplate in CODE REFERENCES on file paths.
Describe in intro(9) how to read paths in the CODE REFERENCES section.

IMPLEMENTATION NOTES back to NOTES.

Use standard section headers.

file kmem.9 was added on branch uebayasi-xip on 2010-08-17 06:40:05 +0000

Mention that kmem_free(9) may block, just in a case it is not clear.

Bump date for new kmem_asprintf.

Start a new paragraph before describing kmem_asprintf().

Add kmem_asprintf rotuine which allocates string accordingly to format
string from kmem pool. Allocated string is string length + 1 char for ending
zero.

Ok: ad@.

Cross-link a little.

Fix typo.

kmem(9): add code references, improve a little.

Unify kmem_alloc/zalloc/free under kmem(9).  Links preserved.
