* | [S390] Change atomic_read/set to inline functions with barrier semantics.Heiko Carstens2007-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | After doing some tests this seems to be the best variant for s390 and should be correct as well. With gcc 4.2.1 we get the following kernel image sizes using the default configuration: atomic_t type volatile, atomic_read/set defines 5311824 bytes atomic_t type int, atomic_read/set defines 5270864 bytes atomic_t type int, atomic_read/set inline asm 5279056 bytes atomic_t type int, atomic_read/set inline barrier 5270864 bytes Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* | [S390] vmur: fix diag14 exceptions with addresses > 2GB.Michael Holzheu2007-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | There are several s390 diagnose calls, which must be executed below the 2GB memory boundary. In order to enforce this, those diagnoses must be compiled into the kernel. Currently diag 14 can be called within the vmur kernel module from addresses above 2GB. This leads to specification exceptions. This patch moves diag10, diag14 and diag210 into the new diag.c file.

This regression got slightly introduced with commit b7471c6da94d30d3deadc55986cc38d1ff57f9ca. Introduced NMI_DISABLED (-1) which allows to switch the value of NMI_DEFAULT without breaking the APIC NMI watchdog code (again).

* | i386: Fix a couple busy loops in mach_wakecpu.h:wait_for_init_deassert()Satyam Sharma2007-08-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use cpu_relax() in the busy loops, as atomic_read() doesn't automatically imply volatility for i386 and x86_64. x86_64 doesn't have this issue because it open-codes the while loop in smpboot.c:smp_callin() itself that already uses cpu_relax(). For i386, however, smpboot.c:smp_callin() calls wait_for_init_deassert() which is buggy for mach-default and mach-es7000 cases. [ I test-built a kernel -- smp_callin() itself got inlined in its only callsite, smpboot.c:start_secondary() -- and the relevant piece of code disassembles to the following: 0xc1019704 <start_secondary+12>: mov 0xc144c4c8,%eax 0xc1019709 <start_secondary+17>: test %eax,%eax 0xc101970b <start_secondary+19>: je 0xc1019709 <start_secondary+17> init_deasserted (at 0xc144c4c8) gets fetched into %eax only once and then we loop over the test of the stale value in the register only, so these look like real bugs to me. With the fix below, this becomes: 0xc1019706 <start_secondary+14>: pause 0xc1019708 <start_secondary+16>: cmpl $0x0,0xc144c4c8 0xc101970f <start_secondary+23>: je 0xc1019706 <start_secondary+14> which looks nice and healthy. ] Thanks to Heiko Carstens for noticing this.

This is one weird area of ieee1754 handling in that the underflow behavior changes based upon whether underflow is enabled in the trap enable mask of the FPU control register. As a specific case the Sparc V9 manual gives us the following description: -------------------- If UFM = 0: Underflow occurs if a nonzero result is tiny and a loss of accuracy occurs. Tininess may be detected before or after rounding. Loss of accuracy may be either a denormalization loss or an inexact result. If UFM = 1: Underflow occurs if a nonzero result is tiny. Tininess may be detected before or after rounding. -------------------- What this amounts to in the packing case is if we go subnormal, we set underflow if any of the following are true: 1) rounding sets inexact 2) we ended up rounding back up to normal (this is the case where we set the exponent to 1 and set the fraction to zero), this should set inexact too 3) underflow is set in FPU control register trap-enable mask The initially discovered example was "DBL_MIN / 16.0" which incorrectly generated an underflow. It should not, unless underflow is set in the trap-enable mask of the FPU csr. Another example, "0x0.0000000000001p-1022 / 16.0", should signal both inexact and underflow. The cpu implementations and ieee1754 literature is very clear about this. This is case #2 above. However, if underflow is set in the trap enable mask, only underflow should be set and reported as a trap. That is handled properly by the prioritization logic in arch/sparc{,64}/math-emu/math.c:record_exception(). Based upon a report and test case from Jakub Jelinek. Signed-off-by: David S.

* | | | | | [AVR32] Define mmiowb()Haavard Skinnemoen2007-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add empty definition of mmiowb() since some drivers need it. Uncached writes are strongly ordered on AVR32. They may be delayed if the dcache is busy doing a writeback, but AFAICT that's not what this macro is supposed to deal with, at least on UP systems. We might have to revisit this definition when a SMP-capable AVR32 CPU comes along, depending on how the busses and cache coherency stuff end up being implemented.

* | | | | | [AVR32] Fix bogus pte_page() definitionHaavard Skinnemoen2007-08-15

This may lead to everything from mmap() silently accessing the wrong data to "invalid pte" errors dumped by the kernel. Also remove the now-unused definition of PTE_PHYS_MASK.

* | | | | [NET]: Share correct feature code between bridging and bondingHerbert Xu2007-08-14

For example, if you bond devices with NETIF_F_HW_CSUM and NETIF_F_IP_CSUM you'll end up with a bonding device that has neither flag set. If both have TSO then this produces an illegal combination. The bridge device on the other hand has the correct code to deal with this. In fact, the same code can be used for both. So this patch moves that logic into net/core/dev.c and uses it for both bonding and bridging. In the process I've made small adjustments such as only setting GSO_ROBUST if at least one constituent device supports it.

Current memory allocation for acpi_perf_data is actually open-coded alloc_percpu(). The patch defines and handles acpi_perf_data as percpu data. The code will be cleaner and easier to be maintained with this change. 2. Won't load driver in acpi_cpufreq_early_init() failure case. 3. Add __init for acpi_cpufreq_early_init().

First, the code that generates the pci devices from the OF device-tree doesn't initialize the mask properly, then our implementation of set_dma_mask() was trying to validate the -previous- mask value, not the one passed in as an argument.
