To: Andrew Morton; +Cc: linux-kernel, linux-mm, x86, linux-arch, peterz
The KM_type parameter for kmap_atomic/kunmap_atomic is not used anymore
since commit 3e4d3af(mm: stack based kmap_atomic()).
So convert k{un}map_atomic(p, KM_type) to k{un}map_atomic(p).
Most conversion are done by below commands. Some are done by hand.
find . -type f | xargs sed -i 's/\(kmap_atomic(.*\),\ .*)/\1)/'
find . -type f | xargs sed -i 's/\(kunmap_atomic(.*\),\ .*)/\1)/'
Build and tested on 32/64bit x86 kernel(allyesconfig) with 3G memory.
ARM, MIPS, PowerPc and Sparc are build tested only with
CONFIG_HIGHMEM=y and CONFIG_HIGHMEM=n.
I don't have cross-compiler for other arches.

* [PATCH 1/2] mm: convert k{un}map_atomic(p, KM_type) to k{un}map_atomic(p)
@ 2011-08-26 8:17 ` Lin Ming

From: Lin Ming @ 2011-08-26 8:17 UTC (permalink / raw)
To: Andrew Morton; +Cc: linux-kernel, linux-mm, x86, linux-arch, peterz
The KM_type parameter for kmap_atomic/kunmap_atomic is not used anymore
since commit 3e4d3af(mm: stack based kmap_atomic()).
So convert k{un}map_atomic(p, KM_type) to k{un}map_atomic(p).
Most conversion are done by below commands. Some are done by hand.
find . -type f | xargs sed -i 's/\(kmap_atomic(.*\),\ .*)/\1)/'
find . -type f | xargs sed -i 's/\(kunmap_atomic(.*\),\ .*)/\1)/'
Build and tested on 32/64bit x86 kernel(allyesconfig) with 3G memory.
ARM, MIPS, PowerPc and Sparc are build tested only with
CONFIG_HIGHMEM=y and CONFIG_HIGHMEM=n.
I don't have cross-compiler for other arches.

Stuff like that is really only a half-assed cleanup, IIRC there's more
sites like that.
In my initial massive patch I cleaned all that up as well.

I'm OK with cleaning all these up, but I suggest that we leave the
back-compatibility macros in place for a while, to make sure that
various stragglers get converted. Extra marks will be awarded for
working out how to make unconverted code generate a compile warning ;)
Perhaps you could dust off your old patch and we'll bring it up to date?

It's possible to (ab)use the C preprocessor to accomplish this sort of
thing. For instance, consider the following:
#include <stdio.h>
int foo(int x)
{
return x;
}
/* Deprecated; call foo instead. */
static inline int __attribute__((deprecated)) foo_unconverted(int x, int unused)
{
return foo(x);
}
#define PASTE(a, b) a ## b
#define PASTE2(a, b) PASTE(a, b)
#define NARG_(_9, _8, _7, _6, _5, _4, _3, _2, _1, n, ...) n
#define NARG(...) NARG_(__VA_ARGS__, 9, 8, 7, 6, 5, 4, 3, 2, 1, :)
#define foo1(...) foo(__VA_ARGS__)
#define foo2(...) foo_unconverted(__VA_ARGS__)
#define foo(...) PASTE2(foo, NARG(__VA_ARGS__)(__VA_ARGS__))
int main(void)
{
printf("%d\n", foo(42));
printf("%d\n", foo(54, 42));
return 0;
}
The preprocessor will select between "foo" and "foo_unconverted"
depending on the number of arguments passed; and gcc will emit a warning
for the latter case:
% gcc test.c
test.c: In function ‘main’:
test.c:27: warning: ‘foo_unconverted’ is deprecated (declared at test.c:9)

most of it would be doing what mlin just did, so I took his patch and
went from there, the resulting delta is something like the below.
Completely untested... crypto much improved since I last looked at it.
---
Whoever wrote aesni-intel_glue.c should be flogged, it did 3
kmap_atomic()s on the same km_type.. it works with the stacked kmap but
still we should not nest 3 kmaps, that's just wrong.
Crypto: mostly cleanup of the out/in_softirq() km_type selection and
cleanup of some of the scatterwalk stuff that had superfluous arguments
etc..
drbd: cleaned up more, could probably be sanitized even further but will
leave that to the maintainers.
mmc: looks like mlin made a boo-boo there, but it also looks like
tmio_mmc_kmap_atomic and co can be somewhat improved..
cassini: removal of useless cas_page_map/unmap wrappers
fc: removed some pointless km_type passing around
rtl8192u: again, someone should be flogged, private (slightly
'improved') copy of scatterwalk.[ch].
zram: removed put/get_ptr_atomic foo
bio: git grep __bio_kmap_atomic/kunmap_atomic turned up empty

most of it would be doing what mlin just did, so I took his patch and
went from there, the resulting delta is something like the below.
Completely untested... crypto much improved since I last looked at it.
---
Whoever wrote aesni-intel_glue.c should be flogged, it did 3
kmap_atomic()s on the same km_type.. it works with the stacked kmap but
still we should not nest 3 kmaps, that's just wrong.
Crypto: mostly cleanup of the out/in_softirq() km_type selection and
cleanup of some of the scatterwalk stuff that had superfluous arguments
etc..
drbd: cleaned up more, could probably be sanitized even further but will
leave that to the maintainers.
mmc: looks like mlin made a boo-boo there, but it also looks like
tmio_mmc_kmap_atomic and co can be somewhat improved..
cassini: removal of useless cas_page_map/unmap wrappers
fc: removed some pointless km_type passing around
rtl8192u: again, someone should be flogged, private (slightly
'improved') copy of scatterwalk.[ch].
zram: removed put/get_ptr_atomic foo
bio: git grep __bio_kmap_atomic/kunmap_atomic turned up empty

most of it would be doing what mlin just did, so I took his patch and
went from there, the resulting delta is something like the below.
Completely untested... crypto much improved since I last looked at it.
---
Whoever wrote aesni-intel_glue.c should be flogged, it did 3
kmap_atomic()s on the same km_type.. it works with the stacked kmap but
still we should not nest 3 kmaps, that's just wrong.
Crypto: mostly cleanup of the out/in_softirq() km_type selection and
cleanup of some of the scatterwalk stuff that had superfluous arguments
etc..
drbd: cleaned up more, could probably be sanitized even further but will
leave that to the maintainers.
mmc: looks like mlin made a boo-boo there, but it also looks like
tmio_mmc_kmap_atomic and co can be somewhat improved..
cassini: removal of useless cas_page_map/unmap wrappers
fc: removed some pointless km_type passing around
rtl8192u: again, someone should be flogged, private (slightly
'improved') copy of scatterwalk.[ch].
zram: removed put/get_ptr_atomic foo
bio: git grep __bio_kmap_atomic/kunmap_atomic turned up empty
