2005-10-29[PATCH] ppc32: ppc_sys fixes for 8xx and 82xxVitaly Bordug
This patch fixes a numbers of issues regarding to that both 8xx and 82xx began to use ppc_sys model: - Platform is now identified by default deviceless SOC, if no BOARD_CHIP_NAME is specified in the bard-specific header. For the list of supported names refer to (arch/ppc/syslib/) mpc8xx_sys.c and mpc82xx_sys.c for 8xx and 82xx respectively. - Fixed a bug in identification by name - if the name was not found, it returned -1 instead of default deviceless ppc_spec. - fixed devices amount in the 8xx platform system descriptions Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com> Signed-off-by: Marcelo Tosatti <marcelo.tosatti@cyclades.com> Signed-off-by: Kumar Gala <kumar.gala@freescale.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-29[PATCH] ppc: make phys_mem_access_prot() work with pfns instead of addressesRoland Dreier
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.

2005-10-29[PATCH] MPC8xx PCMCIA driverMarcelo Tosatti
Here is an uptodated version of the MPC8xx PCMCIA driver for v2.6, addressing comments by Jeff and Dominik: - use IO accessors instead of direct device memory referencing - avoid usage of non-standard "uint/uchar" data types - kill struct typedef's Will submit it for inclusion once v2.6.14 is out.

2005-10-29[PATCH] ppc32 8xx: use io accessor macros instead of direct memory referenceMarcelo Tosatti
Convert core 8xx drivers to use in_xxxbe/in_xxx macros instead of direct memory references. Other than making IO accesses explicit (which is a plus for readability), a common set of macros provides a unified place for the volatile flag to constraint compiler code reordering. There are several unlucky places at the moment which lack the volatile flag.

2005-10-29[PATCH] ppc: prevent GCC 4 from generating AltiVec instructions in kernelLee Nicks
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.

2005-10-28powerpc: Merge xmonPaul Mackerras
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').

2005-10-27[TCP]: Clear stale pred_flags when snd_wnd changesHerbert Xu
This bug is responsible for causing the infamous "Treason uncloaked" messages that's been popping up everywhere since the printk was added. 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.
