| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 47d13a269bbd ("powerpc/40x: Remove 40x platforms.") support for PPC40x platforms has been removed. While the EDAC driver also mentions PPC440 and PPC460 processors, the driver refuses to probe on anything other than PPC405. It's unlikely support will ever be added at this point for these other old platforms, so the driver can be removed.

* / minmax: make generic MIN() and MAX() macros available everywhereLinus Torvalds2024-07-291-1/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This just standardizes the use of MIN() and MAX() macros, with the very traditional semantics. The goal is to use these for C constant expressions and for top-level / static initializers, and so be able to simplify the min()/max() macros. These macro names were used by various kernel code - they are very traditional, after all - and all such users have been fixed up, with a few different approaches: - trivial duplicated macro definitions have been removed Note that 'trivial' here means that it's obviously kernel code that already included all the major kernel headers, and thus gets the new generic MIN/MAX macros automatically. - non-trivial duplicated macro definitions are guarded with #ifndef This is the "yes, they define their own versions, but no, the include situation is not entirely obvious, and maybe they don't get the generic version automatically" case. - strange use case #1 A couple of drivers decided that the way they want to describe their versioning is with #define MAJ 1 #define MIN 2 #define DRV_VERSION __stringify(MAJ) "." __stringify(MIN) which adds zero value and I just did my Alexander the Great impersonation, and rewrote that pointless Gordian knot as #define DRV_VERSION "1.2" instead. - strange use case #2 A couple of drivers thought that it's a good idea to have a random 'MIN' or 'MAX' define for a value or index into a table, rather than the traditional macro that takes arguments. These values were re-written as C enum's instead. The new function-line macros only expand when followed by an open parenthesis, and thus don't clash with enum use. Happily, there weren't really all that many of these cases, and a lot of users already had the pattern of using '#ifndef' guarding (or in one case just using '#undef MIN') before defining their own private version that does the same thing. I left such cases alone. Cc: David Laight <David.Laight@aculab.com> Cc: Lorenzo Stoakes <lorenzo.stoakes@oracle.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* minmax: add a few more MIN_T/MAX_T usersLinus Torvalds2024-07-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 3a7e02c040b1 ("minmax: avoid overly complicated constant expressions in VM code") added the simpler MIN_T/MAX_T macros in order to avoid some excessive expansion from the rather complicated regular min/max macros. The complexity of those macros stems from two issues: (a) trying to use them in situations that require a C constant expression (in static initializers and for array sizes) (b) the type sanity checking and MIN_T/MAX_T avoids both of these issues. Now, in the whole (long) discussion about all this, it was pointed out that the whole type sanity checking is entirely unnecessary for min_t/max_t which get a fixed type that the comparison is done in. But that still leaves min_t/max_t unnecessarily complicated due to worries about the C constant expression case. However, it turns out that there really aren't very many cases that use min_t/max_t for this, and we can just force-convert those. This does exactly that. Which in turn will then allow for much simpler implementations of min_t()/max_t(). All the usual "macros in all upper case will evaluate the arguments multiple times" rules apply. We should do all the same things for the regular min/max() vs MIN/MAX() cases, but that has the added complexity of various drivers defining their own local versions of MIN/MAX, so that needs another level of fixes first.

* | EDAC/synopsys: Fix ECC status and IRQ control race conditionSerge Semin2024-05-061-13/+37

Enable IRQ: a. ECCCLR = EN_CE | EN_UE 2. Disable IRQ: a. ECCCLR = 0 3. IRQ handler: a. ECCCLR = CLR_CE | CLR_CE_CNT | CLR_CE | CLR_CE_CNT b. ECCCLR = 0 c. ECCCLR = EN_CE | EN_UE So if the IRQ disabling procedure is called concurrently with the IRQ handler method the IRQ might be actually left enabled due to the statement 3c. The root cause of the problem is that ECCCLR register (which since v3.10a has been called as ECCCTL) has intermixed ECC status data clear flags and the IRQ enable/disable flags. Thus the IRQ disabling (clear EN flags) and handling (write 1 to clear ECC status data) procedures must be serialised around the ECCCTL register modification to prevent the race. So fix the problem described above by adding the spin-lock around the ECCCLR modifications and preventing the IRQ-handler from modifying the IRQs enable flags (there is no point in disabling the IRQ and then re-enabling it again within a single IRQ handler call, see the statements 3a/3b and 3c above).

However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve this, there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
