2011-02-25omap4: prcm: Fix the CPUx clockdomain offsetsSantosh Shilimkar
CPU0 and CPU1 clockdomain is at the offset of 0x18 from the LPRM base. The header file has set it wrongly to 0x0. Offset 0x0 is for CPUx power domain control register Fix the same. The autogen scripts is fixed thanks to Benoit Cousson With the old value, the clockdomain code would access the *_PWRSTCTRL.POWERSTATE field when it thought it was accessing the *_CLKSTCTRL.CLKTRCTRL field. In the worst case, this could cause system power management to behave incorrectly.

2011-02-22OMAP2/3: clock: fix fint calculation for DPLL_FREQSELJohn Ogness
In OMAP35X TRM Rev 2010-05 Figure 7-18 "DPLL With EMI Reduction Feature", it is shown that the internal frequency is calculated by CLK_IN/(N+1). However, the value passed to _dpll_test_fint() is already "N+1" since Linux is using the values to divide by. In the technical reference manual, "N" is referring to the divider's register value (0-127). During power management testing, it was observed that programming the wrong jitter correction value can cause the system to become unstable and eventually crash.

2011-02-21ARM: tlb: delay page freeing for SMP and ARMv7 CPUsRussell King
We need to delay freeing any mapped page on SMP and ARMv7 systems to ensure that the data is not accessed by other CPUs, or is used for speculative prefetch with ARMv7. This includes not only mapped pages but also pages used for the page tables themselves. This avoids races with the MMU/other CPUs accessing pages after they've been freed but before we've invalidated the TLB. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-02-21ARM: Keep exit text/data around for SMP_ON_UPRussell King

2011-02-21ARM: 6740/1: Place correctly notes section in the linker scriptPawel Moll
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.

2011-02-19ARM: 6741/1: errata: pl310 cache sync operation may be faultySrinidhi Kasagar
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.

2011-02-15x86, ioapic: Don't warn about non-existing IOAPICs if we have nonePaul Bolle
mp_find_ioapic() prints errors like: ERROR: Unable to locate IOAPIC for GSI 13 if it can't find the IOAPIC that manages that specific GSI. I see errors like that at every boot of a laptop that apparently doesn't have any IOAPICs. But if there are no IOAPICs it doesn't seem to be an error that none can be found. A solution that gets rid of this message is to directly return if nr_ioapics (still) is zero. (But keep returning -1 in that case, so nothing breaks from this change.) The call chain that generates this error is: pnpacpi_allocated_resource() case ACPI_RESOURCE_TYPE_IRQ: pnpacpi_parse_allocated_irqresource() acpi_get_override_irq() mp_find_ioapic() Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Ingo Molnar <mingo@elte.hu>
