In commit d358788f Author: Russell King <rmk@dyn-67.arm.linux.org.uk> Date: Mon Mar 20 20:00:09 2006 +0000 Glen Turner reported that writing LFCR rather than the more traditional CRLF causes issues with some terminals. Since this afflicts many serial drivers, extract the common code to a library function (uart_console_write) and arrange for each driver to supply a "putchar" function. but early_printk is left out.

Fix boot failures with the early CPUID checking on VIA C3 Includes fixes from Christian Volkmann Signed-off-by:

Christian Volkmann authored
- boot/setup.S did not print "PANIC: CPU too old for this kernel" ( not visible, also the message did not match ) - I add "# missed before: set ds" => somebody should check if I am right with the way to set. => seems to be a generic error in setup.S not to set "ds" for error messages. AK: extracted patch out of other changes AK: also couldn't find any other case where ds is wrong Signed-off-by:

It reports machine check capability in CPUID, but doesn't actually implement all the necessary MSRs of the standard Intel machine check architecture. This fixes a boot failure on K6s recently introduced. Signed-off-by:

Only try to allocate MSRs once instead of for every CPU. This assumes the MSRs are the same on all CPUs which is currently true. P4-HT is a special case for different SMT threads, but the code always saves/restores all MSRs so it works identical. Signed-off-by:

a) platorm_driver_probe(...) instead of platform_driver_register(&driver); b) set bfin_spi_enable and bfin_spi_disable static c) Why is the width flag a u32? d) maybe use dev_dbg() instead of pr_debug() Signed-off-by:

There's a forum thread at https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&_forum_action=MessageReply&message_id=24741 which has a testcase involving signal handling that crashes quite readily. Inspecting the code I believe what happens is that signal handling can become confused when it is invoked on return from an interrupt, if the contents of P0 and R0 at the time of the interrupt happen to be such that P0 is larger than zero (indicating to the signal code that we're in a syscall), and R0 happens to have a value of something like -EINTR or -ERESTARTSYS. Fixed by setting orig_p0 to -1 if we're returning from an interrupt. The testcase now seems to run without problems. Signed-off-by:

Blackfin arch: cache SWRST value at bootup so other things like watchdog can non-destructively query it Signed-off-by:

Bryan Wu authored
a) add new processor BF52x/BF54x header files b) update blackfin BF533/BF537/BF561 header files to latest one in VDSP. c) scrub watchdog/rtc masks from headers as we dont need/want them (too generic and the drivers dont use them) Signed-off-by:

Without conswitchp preset, we have the following situation: - During initcalls: con_init is called, and returns because of !display_desc. - At this point there is no memory allocated for vc_cons[].d A bit later vty_init calls kbd_init. - From now on events are passed to kbd_event which will then call kbd_keycode. - kbd_keycode will oops on a NULL pointer dereference on vc->vc_tty Signed-off-by:

1) Disable Interrupts during DMA memcpy to avoid raise conditions. 2) Mark MDMA channel 0 as reserved, since were using it internally. 3) Add DMA based equivalents for insX and outsX. 4) Our insX and outsX only handles len <= 2^16. Signed-off-by:
