* ARM: Ensure predictable endian state on signal handler entryRussell King2011-02-21
| | | | | | | | | | | Ensure a predictable endian state when entering signal handlers. This avoids programs which use SETEND to momentarily switch their endian state from having their signal handlers entered with an unpredictable endian state.

* ARM: 6740/1: Place correctly notes section in the linker scriptPawel Moll2011-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 18991197b4b588255ccabf472ebc84db7b66a19c added --build-id linker option when toolchain supports it. ARM one does, but for some reason places the section at 0 when linker script doesn't mention it explicitly. The 1e621a8e3752367d4aae78a8ab00a18fb2793f34 worked around the problem removing this section from binary image with explicit objcopy options, but it still exists in vmlinux, confusing tools like debuggers and perf. This problem was discussed here: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html but the proposed changes to the linker script were substantial. This patch simply places NOTES (36 bytes long, at least when compiled with CodeSourcery toolchain) between data and bss, which seem to be the right place (and suggested by the sample linker script in include/asm-generic/vmlinux.lds.h). It is enough to place it correctly in vmlinux (so debuggers are happy): Section Headers: [11] .data PROGBITS c07ce000 7ce000 020fc0 00 WA 0 0 32 [12] .notes NOTE c07eefc0 7eefc0 000024 00 AX 0 0 4 [13] .bss NOBITS c07ef000 7eefe4 01e628 00 WA 0 0 32 Program Headers: LOAD 0x008000 0xc0008000 0xc0008000 0x7e6fe4 0x805628 RWE 0x8000 NOTE 0x7eefc0 0xc07eefc0 0xc07eefc0 0x00024 0x00024 R E 0x4 Section to Segment mapping: Segment Sections... 00 <...> .data .notes .bss 01 .notes and to get it exposed as /sys/kernel/notes used by perf tools.

* ARM: 6741/1: errata: pl310 cache sync operation may be faultySrinidhi Kasagar2011-02-19
| | | | | | | | | | | | | | | | | | | | | | The effect of cache sync operation is to drain the store buffer and wait for all internal buffers to be empty. In normal conditions, store buffer is able to merge the normal memory writes within its 32-byte data buffers. Due to this erratum present in r3p0, the effect of cache sync operation on the store buffer still remains when the operation completes. This means that the store buffer is always asked to drain and this prevents it from merging any further writes. This can severely affect performance on the write traffic esp. on Normal memory NC one. The proposed workaround is to replace the normal offset of cache sync operation(0x730) by another offset targeting an unmapped PL310 register 0x740.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Uwe pointed out that my alarm based UIE emulation is not sufficient to replace the older timer/polling based UIE emulation on devices where there is no alarm irq. This causes rtc devices without alarms to return -EINVAL to UIE ioctls. The fix is to re-instate the old timer/polling method for devices without alarm irqs. This patch reverts the following commits: 042620a018afcfba1d678062b62e46 - Remove UIE emulation 1daeddd5962acad1bea55e524fc0fa - Cleanup removed UIE emulation declaration b5cc8ca1c9c3a37eaddf709b2fd3e1 - Remove Kconfig symbol for UIE emulation The emulation mode will still need to be wired-in with a following patch before it will work.

In the later cases the sysctl option is present because link notification events can have undesired effects e.g. if the link is flapping. I don't think this applies in the case of an explicit request from a driver. This patch makes NETDEV_NOTIFY_PEER unconditional, if preferred we could add a new sysctl for this case which defaults to on. This change causes Xen post-migration ARP notifications (which cause switches to relearn their MAC tables etc) to be sent by default.

For unknown reason, sometimes after hw scanning, device is not able to receive frames at high rate. Since plcp health check may request hw scan to "reset radio", performance problem start to be observable after update kernel to .35, where plcp check was introduced. Bug reporter confirmed that removing plcp check fixed problem for him.

If alloc_skb() fails to allocate memory and returns NULL then we want to return -ENOMEM from drivers/atm/solos-pci.c::popen() regardless of the value of net_ratelimit(). The way the code is today, we may not return if net_ratelimit() returns 0, then we'll proceed to pass a NULL pointer to skb_put() which will blow up in our face. This patch ensures that we always return -ENOMEM on alloc_skb() failure and only let the dev_warn() be controlled by the value of net_ratelimit().

I could just add a 'if (serial)' test at the 'exit' label, but since most freeing functions in the kernel accept NULL pointers (and it seems like this was also assumed here) I opted to instead change 'hso_free_tiomget()' so that it is safe to call it with a NULL argument. I also modified the function to get rid of a pointles conditional before the call to 'usb_free_urb()' since that function already tests for NULL itself - besides fixing the NULL deref this change also buys us a few bytes in size.
