* [PATCH] ppc64: AC Power handling broken for desktopsOlaf Hering2005-10-29
| | | | | | | | | | Currently, AC Power is 0 on a desktop G4. No batteries present should mean AC Power == 1. Signed-off-by: Olaf Hering <olh@suse.de> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] ppc64 boot: print firmware provided stackpointerOlaf Hering2005-10-29
| | | | | | | | | | | | | | | Show firmware provided stackpointer during boot. This helps to find the "taboo" areas on the various boards. claim tends to fail for these memory areas, but some jokers return success anyway. Use %p to print the load address, its a pointer.

* [PATCH] ppc64 boot: remove need for imagesize.cOlaf Hering2005-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Compute the vmlinux size at runtime. Use Z_FULL_FLUSH instead of Z_FINISH, to extract only the ELF header and ELF program header. ->p_memsz is the required memory range for the executable, including bss ->p_filesz is the size of .text, .data and other runtime sections These values must be used for the claim call. All additional memory needed by the kernel is claimed in prom_init, remove the extra Mb. Pass the full memsize as target area to gunzip, otherwise not everything will be uncompressed. flush_cache has to flush all runtime sections, do not reduce the memrange by the ->p_offset value because its just that: an offset. Remove the Makefile code to produce an imagesize.c, its not needed anymore. Remove all FORCE flags, to not rebuild the zImage if vmlinux was not changed.

* [PATCH] ppc: make phys_mem_access_prot() work with pfns instead of addressesRoland Dreier2005-10-29
| | | | | | | | | | | | | | | | | | Change the phys_mem_access_prot() function to take a pfn instead of an address. This allows mmap64() to work on /dev/mem for addresses above 4G on 32-bit architectures. We start with a pfn in mmap_mem(), so there's no need to convert to an address; in fact, it's actively bad, since the conversion can overflow when the address is above 4G. Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an address by directly comparing to max_pfn. Working with max_pfn instead of high_memory fixes page_is_ram() to give the right answer for highmem pages.

| | | | | | | | | | | | | | | | Convert core 8xx drivers to use in_xxxbe/in_xxx macros instead of direct memory references.

* [PATCH] ppc: prevent GCC 4 from generating AltiVec instructions in kernelLee Nicks2005-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Depending on how GCC is built, GCC 4 may generate altivec instructions without user explicitly requesting vector operations in the code. Although this is a performance booster for user applications, it is a problem for kernel. This patch explicitly instruct GCC to NOT generate altivec instructions while building the kernel. Here are some test cases I ran. (1) build gcc 4.0.1 with '--with-cpu=7450 --enable-altivec --enable-cxx-flags=-mcpu=7450', and use this gcc to build kernel WITHOUT this kernel patch. Kernel fail to boot up on a 7450 board because of altivec instructions in kernel. (2) build gcc 4.0.1 with "--with-cpu=7450 --enable-altivec --enable-cxx-flags=-mcpu=7450", and use this gcc to build kernel WITH this kernel patch. Kernel boot up on a 7450 board without any problem. (3) build gcc 4.0.1 with "--with-cpu=750 --enable-cxx-flags=-mcpu=750", and use this gcc to build kernel with or without this kernel patch. Kernel boot up on a 7450 board without any problem. This patch should also work with GCC 3 or even earlier GCC 2.95.3.

* powerpc: Merge xmonPaul Mackerras2005-10-28
| | | | | | | | | | | The merged version follows the ppc64 version pretty closely mostly, and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version. The main difference for ppc64 is that the 'p' command to call show_state (which was always pretty dodgy) has been replaced by the ppc32 'p' command, which calls a given procedure (so in fact the old 'p' command behaviour can be achieved with 'p $show_state').

It has usually been blamed on foreign operating systems. However, some of those reports implicate Linux as both systems are running Linux or the TCP connection is going across the loopback interface. In fact, there really is a bug in the Linux TCP header prediction code that's been there since at least 2.1.8. This bug was tracked down with help from Dale Blount. The effect of this bug ranges from harmless "Treason uncloaked" messages to hung/aborted TCP connections. The details of the bug and fix is as follows. When snd_wnd is updated, we only update pred_flags if tcp_fast_path_check succeeds. When it fails (for example, when our rcvbuf is used up), we will leave pred_flags with an out-of-date snd_wnd value. When the out-of-date pred_flags happens to match the next incoming packet we will again hit the fast path and use the current snd_wnd which will be wrong. In the case of the treason messages, it just happens that the snd_wnd cached in pred_flags is zero while tp->snd_wnd is non-zero. Therefore when a zero-window packet comes in we incorrectly conclude that the window is non-zero. In fact if the peer continues to send us zero-window pure ACKs we will continue making the same mistake. It's only when the peer transmits a zero-window packet with data attached that we get a chance to snap out of it. This is what triggers the treason message at the next retransmit timeout.
