* avr32: remove .note.gnu.build-id section when making vmlinux.binHans-Christian Egtvedt2008-12-171-1/+1
| | | | | | | | | This patch will remove the section .note.gnu.build-id added in binutils 2.18 from the vmlinux.bin binary. Not removing this section results in a huge multiple gigabyte binary and likewize large uImage.

| | | | | | | | | | Make USART initialization conform to Section 24.6.1 in the AT32AP7000 manual, i.e. "To prevent the TXD line from falling when the USART is disabled, the use of an internal pull up is mandatory."

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Latest mainline gives this section mismatch on sparc: The function current_pc() references the variable __init no_sun4u_here. This is often because current_pc lacks a __init annotation or the annotation of no_sun4u_here is wrong. Since current_pc() is used only in early time, it is correct to put it in .init section.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The latest mainline gives this section mismatch on sparc: The function __devinit apc_probe() references a variable __initdata apc_no_idle. If apc_no_idle is only used by apc_probe then annotate apc_no_idle with a matching annotation. Since the commit 7e7e2f035663c5ceb029bfb9d91e75099b0a5625, apc_probe() is on __devinit so we have to correct apc_no_idle which is referenced by this function.

Aslo mark corgi_ts.c and corgi_bl.c as deprecated. This unbreaks the legacy configs in {corgi,spitz}_defconfig, however, SPI based ADS7846 touchscreen driver and a new SPI-based corgi_lcd.c driver with integrated backlight support are recommended.

A smoother migration path would be making corgi_ts.c and other drivers depending on corgi_ssp.c and corgi_lcd.c to depend on BROKEN instead, and still allows those to exist around for some time.

And *pos has been increased by 1 by the caller(seq_read()). if this time the cpu#*pos is offline, c_start() will return NULL, and the next cpus can not be shown. this fix use next_cpu_nr(*pos - 1, cpu_online_map) to search the next unshown cpu. the most easy way to reproduce this bug: 1) offline cpu#1 (cpu#0 is online) 2) dd ibs=2 if=/proc/cpuinfo the result is that only cpu#0 is shown. cpu#2 and cpu#3 .... cannot be shown in /proc/cpuinfo it's bug.

For further information, see http://bugzilla.kernel.org/show_bug.cgi?id=11516 Instead of removing the related dmi-quirks completely we'd like to keep them for (at least) one kernel version -- to double-check whether the early-quirks really took effect. But the dmi-quirks need to be called after early-quirks are executed. With this patch calling sequence for dmi-quriks is changed as follows: acpi_boot_table_init() (dmi-quirks) ... early_quirks() (detect bogus IRQ0 override) ... acpi_boot_init() (late dmi-quirks and setup IO APIC) Note: Plan is to remove the "late dmi-quirks" with next kernel version.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a corner case in 32 bit x86 kdump at the moment. When the box panics via nmi, we call bust_spinlocks(1) to disable sensitivity to the console_sem (allowing us to print to the console in all cases), but we don't call crash_kexec, until after we call bust_spinlocks(0), which re-enables console_sem sensitivity. The result is that, if we get an nmi while the console_sem is held and kdump is configured, and we try to print something to the console during kdump shutdown (which we often do) we deadlock the box. The fix is to simply do what 64 bit die_nmi does which is to not call bust_spinlocks(0) until after we call crash_kexec. Patch below tested successfully by me.

The machine check handler only runs when the system is broken and needs to finish as quickly as possible. Remove the respective bogus post 2.6.27 regression and call the machine check vector directly again. This removes only code.
