| * ARM: 5886/1: arm: Fix cpu_proc_fin() for proc-v7.S and make kexec workTony Lindgren2010-01-191-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The comments in arm_machine_restart() suggest that cpu_proc_fin() will clean and disable cache and turn off interrupts. This does not seem to be implemented for proc-v7.S, implement it the same way as for proc-v6.S. This also makes kexec work for v7. Note that a related TLB and branch traget flush patch is also needed to avoid kexec "crc error". Note that there are still some issues that seem to be related to L2 cache being on and causing occasional uncompress "crc error" with kexec. Anyways, this gets kexec mostly working on V7 for now.

| | | | | | | | | | | | | | | | | | | | | | We need to do that if we tinker with the MMU entries. This fixes the occasional bug with kexec where the new fails to uncompress with "crc error". Most likely at least kexec on v6 and v7 need this fix. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * ARM: 5884/1: arm: Fix DCC console for v7Tony Lindgren2010-01-193-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this patch arch/arm/compressed/head.S defaults to generic DCC code that does not work for v7. For more information on the v7 DCC, see Cortex-A8 TRM "12.11.1 Debug communications channel". To use it with post 2.6.33-rc1 or later, you need to have: CONFIG_DEBUG_LL=y ONFIG_DEBUG_ICEDCC=y CONFIG_EARLY_PRINTK=y Earlier kernels need commit 93fd03a8c6728b58879f8af20ffd55d9c32a778b backported.

| * ARM: 5883/1: Revert "disable NX support for OABI-supporting kernels"Rabin Vincent2010-01-181-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 14f0aa359365e8a93a77b71e3b840274b9b4dcb1. That commit was needed earlier because system call restarting for OABI (compat) required an executable stack and thus had problems with NX. Since ab72b00734ae4d0b ("ARM: Fix signal restart issues with NX and OABI compat") has reworked the code to not require an executable stack anymore, we can re-enable NX support for kernels with OABI (compat) support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | flush(void) Because of the include of the decompress_inflate.c file from boot/compress/misc.c, there are different flush() defines: In file included from arch/arm/boot/compressed/misc.c:249: arch/arm/boot/compressed/../../../../lib/decompress_inflate.c:138:29: error: macro "flush" passed 2 arguments, but takes just 0 Fix this by removing the define of flush() in misc.c for CONFIG_DEBUG_ICEDCC as it's already defined in mach/uncompress.h, and that is being included unconditionally. Also use a static inline function instead of define for mach-mxc and mach-gemini to avoid similar bug for those platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The file arch/arm/include/asm/cpu.h needs to include 'linux/cpu.h' to meet its dependency. Otherwise when using "struct cpuinfo_arm" and including just 'asm/cpu.h' throws below error - arch/arm/include/asm/cpu.h:16: error: field 'cpu' has incomplete type To fix this otherway, one can also include both linux/cpu.h and asm/cpu.h but it shoudn't be that way. So this patch fixes this by including the linux/cpu.h in asm/cpu.h, so that including alone asm/cpu.h is enough.

"Following reset, the L2 Unified Cache Enable bit is cleared. To enable the L2 Cache, software may set the bit to a '1' before or at the same time as enabling the MMU. Enabling the L2 Cache after the MMU has been enabled or disabling the L2 Cache after the L2 Cache has been enabled, may result in unpredictable behavior of the processor." When outer cache is initialized, the MMU is already enabled. We couldn't enable L2 after MMU enabled.

Once init data was freed, these pointers went to null, and the next enable or disable call caused the kernel to crash. This change removes this decoration.

(OMAP1 clock: convert mach-omap1/clock.h to mach-omap1/clock_data.c). Prior to this, it was just assumed that these clocks existed for all devices, and it was used directly instead of calling it out with a clock_get call or similar. So, not having the CK_7XX meant these clocks weren't being used anymore for omap 7xx devices, which broke things badly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Out of the three major OMAP2 chip types, OMAP2420, OMAP2430, and OMAP3430, we only map the IVA on OMAP2420. The memory mapping is not shared between OMAP2420 and OMAP2430, so it is inappropriate to label those macros as '24XX'; this patch changes them to '2420'.
