Instead, just return 1 if there is a difference, else 0.
Fixed by ray@ in 2008 but the libkern version was not synced.

MI boot.c's "a-x" fchmod on bsd.upgrade is the only caller that checks the
return value and that call can fail on, e.g. softraid volumes.
Stop clobbering the actual fchmod return value and get that warning printed.

New warning -Warray-parameter is a bit overzealous.

If __builtin_ctzl() is used on sparc64, gcc 4.2 will emit a call to
__ctzdi2. For userland this is in libgcc or compiler-rt. In the kernel
we put these functions in libkern.

We're not maintaining a this as a fork, it's upstream source with a handful
of patches. Thus, the RCS ids aren't particularly useful or important. They
are a bit of a maintenance burden and generate noise in diffs.

Only boot-loader changes are needed. Both installboot(8) and
the kernel already do what is required to make this work.

The kernel source assumes the original zlib ABI. There is no reason to
stick to this local change. Pull in a fix matching ctfdump.c -r1.26.
This is hopefully the last change necessary to undo a painful hack that
was committed 19 years ago without ok. Someone owes me a lot of beer...

commit ec3df00224d4b396e2ac6586ab5d25f673caa4c2

Correct incorrect inputs provided to the CRC functions.
The previous releases of zlib were not sensitive to incorrect CRC
inputs with bits set above the low 32. This commit restores that
behavior, so that applications with such bugs will continue to
operate as before.

and gkoehler for macppc and powerpc64, thanks!

Backport zlib fix for the multi line CLEAR_HASH macro. There is
an else branch where only half of the macro is executed conditionally.
Acording to upstream comment this has only little impact.

writing to disk using the Open Firmware interfaces is buggy and causes
corruption of the disk. While it isn't entirely clear what versions
of Open Firmware are affected, but it seems to only affect IDE drives.
So if we detect an IDE drive, disable writing to it. This results in
a small lose of bootloader functionality (bsd.upgrade loop prevention
and flagging /etc/random.seed re-use) but that is better than losing
the ability to run OpenBSD at all.
Based on a diff by Ted Bullock (who did all the hard work of debugging
this and coming up with a viable fix).

I should have used Byte (unsigned char) which led to passing twice the
correct size to free.

Rebased version of a diff from miod who described it as follows:
This tries to keep diffability against upstream, hence a questionable
choice of the size type for zcfree() - but all sizes should fit in 32
bits anyway.
Since all zcfree routines used in the tree cope with NULL arguments
(including the various alloc.c used by the boot blocks), I have
simplified TRY_FREE to compensate for the growth.

These library functions were added as stopgaps because GCC 4.2.1
lacks the corresponding __sync_* builtins on mips64. However,
the builtins are now provided by Clang.

option BUILDFIXED -- which is incompatible with kernel hibernate unpack since
it places side-effects into BSS, rather than inside z_streamp or using
the private allocator. While here DYNAMIC_CRC_TABLE could cause similar
problems, so disable this also.
Space savings for the media is best done with bootblock-specific libz
compile options, coming in the following commit.
