Patch from Nicolas Pitre This patch adds the required code to support both user space ABIs at the same time. A second syscall table is created to include legacy ABI syscalls that need an ABI compat wrapper. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Patch from Nicolas Pitre The difference between EABI and the legacy ABI may affect either structure member alignment and/or argument register selection. The patch has the details. Included are wrappers for the following syscalls: sys_stat64 sys_lstat64 sys_fstat64 sys_fcntl64 sys_epoll_ctl sys_epoll_wait sys_ipc sys_semop sys_semtimedop sys_pread64 sys_pwrite64 sys_truncate64 sys_ftruncate64 sys_readahead Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Patch from Nicolas Pitre struct statfs64 has extra padding with EABI growing its size from 84 to 88. This struct is now __attribute__((packed,aligned(4))) with a small assembly wrapper to force the sz argument to 84 if it is 88 to avoid copying the extra padding over user space memory unexpecting it.

Patch from Nicolas Pitre This adds the configuration option, and disables any FPA floating point emulators which are not EABI compatible. It also disables Acorn RISC OS/Arthur binary support when CONFIG_EABI=y since it is incompatible with an EABI kernel.

Patch from Nicolas Pitre Fix a few syscalls for EABI requirements. They were sys_pread64 and sys_pwrite64 where the last argument is now entirely pushed on stack, but since commit 567bd980 they don't require any fixup. Remains only the stat64 structure. Non EABI kernels are unaffected. Signed-off-by: Nicolas Pitre Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Patch from Nicolas Pitre For a while we wanted to change the way syscalls were called on ARM. Instead of encoding the syscall number in the swi instruction which requires reading back the instruction from memory to extract that number and polluting the data cache, it was decided that simply storing the syscall number into r7 would be more efficient. Since this represents an ABI change then making that change at the same time as EABI support is the right thing to do. It is now expected that EABI user space binaries put the syscall number into r7 and use "swi 0" to call the kernel. Syscall register argument are also expected to have "EABI arrangement" i.e. 64-bit arguments should be put in a pair of registers from an even register number. Example with long ftruncate64(unsigned int fd, loff_t length): legacy ABI: - put fd into r0 - put length into r1-r2 - use "swi #(0x900000 + 194)" to call the kernel new ARM EABI: - put fd into r0 - put length into r2-r3 (skipping over r1) - put 194 into r7 - use "swi 0" to call the kernel Note that it is important to use 0 for the swi argument as backward compatibility with legacy ABI user space relies on this. The syscall macros in asm-arm/unistd.h were also updated to support both ABIs and implement the right call method automatically.

Patch from Nicolas Pitre We must make sure that assembly code that modifies the stack pointer before calling a C function does it so it remains 64-bit aligned. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Patch from Nicolas Pitre The ARM EABI says that the stack pointer has to be 64-bit aligned for reasons already mentioned in patch #3101 when calling C functions. We therefore must verify and adjust sp accordingly when taking an exception from kernel mode since sp might not necessarily be 64-bit aligned if the exception occurs in the middle of a kernel function. If the exception occurs while in user mode then no sp fixup is needed as long as sizeof(struct pt_regs) as well as any additional syscall data stack space remain multiples of 8.

Patch from Nicolas Pitre Although ARM is still using 32-bit pointers, version 5 and later versions of the ARM architecture introduced the ldrd and strd instructions to move 64-bit data which must be 64-bit aligned in memory, and the EABI includes new constraints on structure data alignment to allow for the compiler to use those instructions. This means that any slab allocation must start on a 64-bit boundary which is not equivalent to BYTES_PER_WORD, especially on those architecture versions that implements the ldrd/strd instructions. Overriding the default alignment disables some slab debug features. If those debug features are really needed then the kernel will have to be compiled for version 4 of the ARM architecture.

Patch from Lennert Buytenhek For the ixp2000 netdev driver, we need to map in a chunk of SRAM (to store the transmit and receive descriptors) and the scratch get/put area (so that we can use the scratchpad rings in the cpu for managing the descriptors.) These are the final two mappings needed for the netdev driver and the last missing piece for the driver in mainline to work.

At least some versions of the via-velocity hardware only support checksumming IPv4 frames in hardware. However, the driver is currently setting the NETIF_F_HW_CSUM flag, which indicates support for more than just IPv4. This results in errors when trying to use IPv6 over via-velocity hardware.

I believe I see the race Michael refers to (tlb_choose_channel may set head, which tlb_init_slave clears), although I was not able to reproduce it. I have updated his patch for the current netdev-2.6.git tree and added a version update. His original comment follows: Our systems have been crashing during testing of PCI HotPlug support in the various networking components. We've faulted in the bonding driver due to a bug in bond_alb.c:tlb_clear_slave() In that routine, the last modification to the TLB hash table is made without protection of the lock, allowing a race that can lead tlb_choose_channel() to select an invalid table element. -J Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

This patch allows the Atmel driver to work correctly with wpa_supplicant and other programs that require some conformance with WEXT-18. It should not affect current behavior of the driver. The patch does four things: 1) Implements SIOCSIWENCODEEXT, SIOCGIWENCODEEXT, SIOCSIWAUTH, and SIOCGIWAUTH calls for unencrypted and WEP operation 2) Accepts zero-filled addresses for SIOCSIWAP, which are legal and should turn off any previous forced WAP address 3) Sends association and de-association events to userspace at most of the appropriate times 4) Fixes erroneous order of CIPHER_SUITE_WEP_* arguments in one location which are actually unused anyway Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

ODonnell, Michael authored
We have identified two related bugs in the e100 driver. Both bugs are related to manipulation of the MDI control register. The first problem is that the Ready bit is being ignored when writing to the Control register; we noticed this because the Linux bonding driver would occasionally come to the spurious conclusion that the link was down when querying Link State. It turned out that by failing to wait for a previous command to complete it was selecting what was essentially a random register in the MDI register set. When we added code that waits for the Ready bit (as shown in the patch file below) all such problems ceased. The second problem is that, although access to the MDI registers involves multiple steps which must not be intermixed, nothing was defending against two or more threads attempting simultaneous access. The most obvious situation where such interference could occur involves the watchdog versus ioctl paths, but there are probably others, so we recommend the locking shown in our patch file.
