2019-05-31isdn: remove hisax driverArnd Bergmann
With the decline of ISDN, this seems to have become almost completely obsolete, and even in the past years before that, almost all remaining users appear to have used mISDN instead. Birger Harzenetter noted that he is still using i4l/hisax to take advantage of the 'divert' driver for call diversion, but otherwise uses mISDN on the same hardware. This is a rare edge case as far as I can tell, but we are still breaking an actively used work flow (see https://xkcd.com/1172/). We debated moving i4l/hisax to staging as an intermediate step, but as he is not likely to change the setup, and that would just delay breaking this use case. The alternatives here are to stay on stable kernels < 5.2, to create an external driver repository for isdn4linux, or to add divert functionality to mISDN.

2018-10-22isdn: hfc_{pci,sx}: Avoid empty body if statementsNathan Chancellor
Clang warns: drivers/isdn/hisax/hfc_pci.c:131:34: error: if statement has empty body [-Werror,-Wempty-body] if (Read_hfc(cs, HFCPCI_INT_S1)); ^ drivers/isdn/hisax/hfc_pci.c:131:34: note: put the semicolon on a separate line to silence this warning In my attempt to hide the warnings because I thought they didn't serve any purpose[1], Masahiro Yamada pointed out that {Read,Write}_hfc in hci_pci.c should be using a standard register access method; otherwise, the compiler will just remove the if statements. For hfc_pci, use the versions of {Read,Write}_hfc found in drivers/isdn/hardware/mISDN/hfc_pCI.h while converting pci_io to be 'void __iomem *' (and clean up ioremap) then remove the empty if statements. For hfc_sx, {Read,Write}_hfc are already use a proper register accessor (inb, outb) so just remove the unnecessary if statements.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

2006-10-02[PATCH] isdn: work around excessive udelay()Andrew Morton
As reported in http://bugzilla.kernel.org/show_bug.cgi?id=6970, ISDN can issue excessively-long udelays, which triggers a build-time error on ARM. This is very sucky of ISDN, but I doubt if anyone is going to suddenly fix it. So change the macro to do the microsecond counting itself.

2006-01-08[PATCH] Eliminate __attribute__ ((packed)) warnings for gcc-4.1Jan Blunck
Since version 4.1 the gcc is warning about ignored attributes. This patch is using the equivalent attribute on the struct instead of on each of the structure or union members. GCC Manual: "Specifying Attributes of Types packed This attribute, attached to struct or union type definition, specifies that each member of the structure or union is placed to minimize the memory required. When attached to an enum definition, it indicates that the smallest integral type should be used. Specifying this attribute for struct and union types is equivalent to specifying the packed attribute on each of the structure or union members."

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
