+2013-11-19  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* Makefile.am: Allow STRIP to be empty when creating windowszip.
+
+2013-11-19  Axel Kellermann <axel.kellermann@gmx.de>
+
+	* util/grub.d/30_os-prober.in: Add GRUB_OS_PROBER_SKIP_LIST to
+	selectively skipping systems.
+
+2013-11-19  Colin Watson  <cjwatson@ubuntu.com>
+
+	* Makefile.util.def (grub-mkimage): Add
+	grub-core/osdep/aros/config.c to extra_dist.
+	* conf/Makefile.extra-dist (EXTRA_DIST): Add docs/autoiso.cfg,
+	docs/osdetect.cfg, grub-core/gnulib-fix-null-deref.diff,
+	grub-core/gnulib-fix-width.diff, grub-core/gnulib-no-abort.diff, and
+	grub-core/gnulib-no-gets.diff.
+
+2013-11-19  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	Add automated filesystem checking based on scripts I've used now for
+	quite some time locally. Most of the test require root so they are
+	skipped when run without necessarry privelegies.
+
+2013-11-19  Colin Watson  <cjwatson@ubuntu.com>
+
+	* util/grub-install.c (main): Adjust info messages to match
+	installed paths of grub-bios-setup and grub-sparc64-setup.
+
+2013-11-19  Colin Watson  <cjwatson@ubuntu.com>
+
+	* util/grub-install-common.c (copy_locales): Consistently use
+	grub_util_get_localedir () rather than LOCALEDIR.
+	(grub_install_copy_files): Likewise.
+
+2013-11-19  Josh Triplett  <josh@joshtriplett.org>
+
+	* grub-core/kern/x86_64/efi/startup.S (_start): Align the stack to a
+	16-byte boundary, as required by the x86-64 ABI, before calling
+	grub_main.  In some cases, GCC emits code that assumes this
+	alignment, which crashes if not aligned.  The EFI firmware is also
+	entitled to assume that stack alignment without checking.
+
+2013-11-18  Josh Triplett  <josh@joshtriplett.org>
+
+	* grub-core/mmap/efi/mmap.c (grub_mmap_register): Round up/down to
+	4k page boundaries as expected by firmware rather than 1k
+	boundaries.
+	(grub_mmap_malign_and_register): Likewise.
+
+2013-11-18  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* tests/grub_func_test.in: Decrease RAM size to 512M. With less
+	fragmentation 512M is enough.
+
+2013-11-18  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* grub-core/kern/mm.c (grub_real_malloc): Decrease cut-off of moving the
+	pointer to 32K. This is the size of cache element which is the most
+	common allocation >1K. This way the pointer is always around blocks
+	of 32K and so we keep performance while decreasing fragmentation.
+
+2013-11-18  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* grub-core/kern/mm.c (grub_real_malloc): Don't update the pointer to
+	current memory when allocating large chunks. This significantly
+	decreases memory fragmentation.
+
+2013-11-18  Colin Watson  <cjwatson@ubuntu.com>
+
+	* tests/gzcompress_test.in: Skip if gzip is not installed (unlikely,
+	but for symmetry).
+	* tests/lzocompress_test.in: Skip if lzop is not installed.
+	* tests/xzcompress_test.in: Skip if xz is not installed.
+
+2013-11-18  Colin Watson  <cjwatson@ubuntu.com>

+	* util/grub-mkrescue.c (main): Fix typo.
+
+2013-11-18  Vladimir Serbinenko  <phcoder@gmail.com>

+	files have not been built.
+
+2013-11-18  Colin Watson  <cjwatson@ubuntu.com>
+
+	* grub-core/osdep/unix/hostdisk.c (grub_util_make_temporary_file):

+	on primary master on pseries.
+
+2013-11-18  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* grub-core/tests/videotest_checksum.c: Don't reload unifont if it's

+
+	* util/grub-mkrescue.c (main): Fix a typo to make yeeloong part

+	* grub-core/term/terminfo.c (grub_cmd_terminfo): Fix a typo to make -g
+	work again.
+
+2013-11-18  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* tests/util/grub-shell.in: For powerpc tests put the CD-ROM as primary
+	master since with some combinations of qemu and firmware only primary
+	IDE channel is available.
+
+2013-11-18  Vladimir Serbinenko  <phcoder@gmail.com>
+

+2013-11-18  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* grub-core/lib/sparc64/setjmp.S: Force spilling of current window.
+
+2013-11-18  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	On i386-ieee1275 we run in paged mode. So we need to explicitly map
+	the devices before accessing them.
+
+2013-11-18  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* grub-core/lib/relocator.c (grub_mm_check_real): Accept const char *

+	* util/grub-mkrescue.c (make_image_fwdisk_abs): Insert all partmap
+	modules to be in line with make_image_abs.
+
+2013-11-18  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* include/grub/mips/setjmp.h (grub_jmp_buf): Fix buffer size.
+
+	setjmp.S uses 12 entries but buffer is declared with only 11 entries.
+
+2013-11-17  Ian Campbell  <ijc@hellion.org.uk>
+
+        * grub-core/disk/uboot/ubootdisk.c: Include SCSI disks.
+
+2013-11-17  Vladimir Serbinenko  <phcoder@gmail.com>

+
+2013-11-17  Vladimir Serbinenko  <phcoder@gmail.com>

+	Load gfxmenu.
+
+2013-11-17  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* tests/core_compress_test.in: Use full arguments as grub-mkimage-extra
+	now needs full arguments.
+

+
+	* util/grub-mkrescue.c (main): Add trailing \n in

+	__sparc__ as __sparc64__ isn't actually defined.
+
+2013-11-17  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* tests/util/grub-shell.in: Use escc-ch-b on powerpc. This is missing

+
+	* util/grub-install.c (device_map_check_duplicates): Fix incorrect

+
+2013-11-16  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	Rewrite grub-install, grub-mkrescue, grub-mkstandalone and grub-mknetdir
+	the function of these files exceeds what can be sanely handled in shell
+	in posix-comaptible way. Also writing it in C extends the functionality
+	to non-UNIX-like OS and minimal environments.

+
+	We have only 92K of stack and using over 4K per frame is wasteful
+
+	* grub-core/script/yylex.l (yyalloc), (yyfree), (yyrealloc): Declare
+	as macros so that compiler would remove useless structure on stack.
+	Better solution would be to fix flex not to put this structure on
+	the stack but flex is external program.
+
+2013-11-16  Vladimir Serbinenko  <phcoder@gmail.com>

+	Decrease stack usage in signature verification.

+	rather than stack.
+
+2013-11-16  Vladimir Serbinenko  <phcoder@gmail.com>

+	rather than stack.
+
+2013-11-16  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	Decrease stack usage in JFS.
+
+	We have only 92K of stack and using over 4K per frame is wasteful
+
+	* grub-core/fs/jfs.c (getblk): Allocate on heap rather than on
+	stack. Note: this function is recursive.
+	(grub_jfs_read_inode): Read only part we care about.
+
+2013-11-16  Leif Lindholm <leif.lindholm@linaro.org>
+
+	* grub-core/kern/arm/uboot/startup.S: fix grub_uboot_syscall va_arg
+	handling

+
+2013-11-15  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	Replace libgcc version of ctz with our own.
+
+	On upcoming arm64 port libgcc ctz* are not usable in standalone
+	environment. Since we need ctz* for this case and implementation is
+	in C we may as well use it on all concerned platforms.
+
+2013-11-14  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* configure.ac: Probe for linking format rather than guessing it based
+	on target_os.
+
+2013-11-14  Vladimir Serbinenko  <phcoder@gmail.com>
+
+	* grub-core/disk/xen/xendisk.c (grub_xendisk_fini): Set state to

+
+2013-11-13  Colin Watson  <cjwatson@ubuntu.com>
+
+	* util/grub-install.in (efi_quiet): Fix inverted logic: make
+	efibootmgr quiet when --debug is not used, rather than when it is.
+
+2013-11-13  Colin Watson  <cjwatson@ubuntu.com>

 As you have seen in previous chapter the support matrix is pretty big and some of the configurations are only rarely used. To ensure the quality bootchecks are available for all x86 targets except EFI chainloader, Appleloader and XNU. All x86 platforms have bootcheck facility except ieee1275. Multiboot, multiboot2, BIOS chainloader, ntldr and freebsd-bootloader boot targets are tested only with a fake kernel images. Only Linux is tested among the payloads using Linux protocols.
