2011-05-07ARM: zImage: don't ignore error returned from decompress()Nicolas Pitre
If decompress() returns an error without calling error(), we must not attempt to boot the resulting kernel. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Tested-by: Shawn Guo <shawn.guo@linaro.org> Tested-by: Tony Lindgren <tony@atomide.com>
2011-05-07ARM: zImage: simplify decompress_kernel()Nicolas Pitre
The return value for decompress_kernel() is no longer used. Furthermore, this was obtained and stored in a variable called output_ptr which is a complete misnomer for what is actually the size of the decompressed kernel image. Let's get rid of it.

2011-05-07ARM: zImage: no need to get the decompressed size from the filesystemNicolas Pitre
In commit d239b1dc093d the hardcoded 4x estimate for the decompressed kernel size was replaced by the exact Image file size and passed to the linker as a symbol value. Turns out that this is unneeded as the size is already included at the end of the compressed piggy data. For those compressed formats that don't include this data, the build system already takes care of appending it using size_append in scripts/Makefile.lib. So let's use that instead.

2011-05-07ARM: zImage: the page table memory must be considered before relocationNicolas Pitre
For correctness, the initial page table located right before the decompressed kernel should be considered when determining if relocation is required. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Tested-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Tony Lindgren <tony@atomide.com>
2011-05-07ARM: zImage: make sure not to relocate on top of the relocation codeNicolas Pitre
If the zImage load address is slightly below the relocation address, there is a risk for the copied data to overwrite the copy loop or cache flush code that the relocation process requires. Always bump the relocation address by the size of that code to avoid this issue. Noticed by Tony Lindgren <tony@atomide.com>. While at it, let's start the copy from the restart symbol which makes the above code size computation possible by the assembler directly (same sections), given that we don't need to preserve the code before that point anyway. And therefore we don't need to carry the _start pointer in r5 anymore. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Tested-by: Tony Lindgren <tony@atomide.com>
2011-05-06ARM: zImage: Fix bad SP address after relocating kernelTony Lindgren
Otherwise cache_clean_flush can overwrite some of the relocated area depending on where the kernel image gets loaded. This fixes booting on n900 after commit 6d7d0ae51574943bf571d269da3243257a2d15db (ARM: 6750/1: improvements to compressed/head.S). Thanks to Aaro Koskinen <aaro.koskinen@nokia.com> for debugging the address of the relocated area that gets corrupted, and to Nicolas Pitre <nicolas.pitre@linaro.org> for the other uncompress related fixes.

2011-05-06ARM: zImage: make sure the stack is 64-bit alignedNicolas Pitre
With ARMv5+ and EABI, the compiler expects a 64-bit aligned stack so instructions like STRD and LDRD can be used. Without this, mysterious boot failures were seen semi randomly with the LZMA decompressor. While at it, let's align .bss as well.

There are two alloc_thread_info_node() macros defined (one for debugging and one for normal).

2011-03-29sparc: Use the new genirq functionalityThomas Gleixner
Make use of the new features in genirq: 1) Set the chip flag IRCHIP_EOI_IF_HANDLED, which ensures in the core code that irq_eoi() is only called when the interrupt was handled. That removes the extra status check in the callback. 2) Use the preflow handler, which is called from the fasteoi core code before the device handler. That avoids another status check and the open coded handler redirection. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: sparclinux@vger.kernel.org
