* lib/zlib_inflate/inflate.c: remove fall through warningsCorentin Labbe2018-10-311-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | This patch remove all following fall through warnings by adding /* fall through */ markers. Note that we cannot add "__attribute__ ((fallthrough));" due to it is GCC7 only arch/arm/boot/compressed/../../../../lib/zlib_inflate/inflate.c:384:25: warning: this statement may fall through [-Wimplicit-fallthrough=] arch/arm/boot/compressed/../../../../lib/zlib_inflate/inflate.c:391:25: warning: this statement may fall through [-Wimplicit-fallthrough=] arch/arm/boot/compressed/../../../../lib/zlib_inflate/inflate.c:393:16: warning: this statement may fall through [-Wimplicit-fallthrough=] arch/arm/boot/compressed/../../../../lib/zlib_inflate/inflate.c:430:25: warning: this statement may fall through [-Wimplicit-fallthrough=] arch/arm/boot/compressed/../../../../lib/zlib_inflate/inflate.c:556:25: warning: this statement may fall through [-Wimplicit-fallthrough=] arch/arm/boot/compressed/../../../../lib/zlib_inflate/inflate.c:595:25: warning: this statement may fall through [-Wimplicit-fallthrough=] arch/arm/boot/compressed/../../../../lib/zlib_inflate/inflate.c:602:25: warning: this statement may fall through [-Wimplicit-fallthrough=] arch/arm/boot/compressed/../../../../lib/zlib_inflate/inflate.c:627:25: warning: this statement may fall through [-Wimplicit-fallthrough=] arch/arm/boot/compressed/../../../../lib/zlib_inflate/inflate.c:646:25: warning: this statement may fall through [-Wimplicit-fallthrough=] arch/arm/boot/compressed/../../../../lib/zlib_inflate/inflate.c:696:25: warning: this statement may fall through [-Wimplicit-fallthrough=] It is easy to see that thoses fall through are needed since in each case state->mode are set to the case value just below.

* [ZLIB]: Fix external builds of zlib_inflate code.David S. Miller2007-10-111-47/+0
| | | | | | | | | Move zlib_inflate_blob() out into it's own source file, infutil.c, so that things like the powerpc zImage builder in arch/powerpc/boot/Makefile don't end up trying to compile it. Signed-off-by: David S. Miller <davem@davemloft.net>

* Fix ppp_deflate issues with recent zlib_inflate changesRichard Purdie2007-05-071-3/+5
| | | | | | | | | | | | | | | The last zlib_inflate update broke certain corner cases for ppp_deflate decompression handling. This patch fixes some logic to make things work properly again. Users other than ppp_deflate (the only Z_PACKET_FLUSH user) should be unaffected.

* [PATCH] Fix ppc32 zImage inflatePeter Korsgaard2006-07-311-1/+4
| | | | | | | | | | | | | | | | The recent zlib update (commit 4f3865fb57a04db7cca068fed1c15badc064a302) broke ppc32 zImage decompression as it tries to decompress to address zero and the updated zlib_inflate checks that strm->next_out isn't a null pointer. This little patch fixes it.

* [PATCH] zlib_inflate: Upgrade library code to a recent versionRichard Purdie2006-06-221-210/+876
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upgrade the zlib_inflate implementation in the kernel from a patched version 1.1.3/4 to a patched 1.2.3. The code in the kernel is about seven years old and I noticed that the external zlib library's inflate performance was significantly faster (~50%) than the code in the kernel on ARM (and faster again on x86_32). For comparison the newer deflate code is 20% slower on ARM and 50% slower on x86_32 but gives an approx 1% compression ratio improvement. I don't consider this to be an improvement for kernel use so have no plans to change the zlib_deflate code. Various changes have been made to the zlib code in the kernel, the most significant being the extra functions/flush option used by ppp_deflate. This update reimplements the features PPP needs to ensure it continues to work. This code has been tested on ARM under both JFFS2 (with zlib compression enabled) and ppp_deflate and on x86_32. JFFS2 sees an approx. 10% real world file read speed improvement. This patch also removes ZLIB_VERSION as it no longer has a correct value. We don't need version checks anyway as the kernel's module handling will take care of that for us. This removal is also more in keeping with the zlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I've added something to the zlib.h header to note its a modified version.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+248
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
